The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™ wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The image processing module 235 may perform pre-processing or post-processing (e.g., adjustment of resolution, brightness, or size) with respect to at least part of the image data. According to an embodiment, the pre-processing or post-processing may be performed, for example, based at least in part on one or more characteristics of the image data or one or more characteristics of the display 210. The mapping module 237 may generate a voltage value or a current value corresponding to the image data pre-processed or post-processed by the image processing module 235. According to an embodiment, the generating of the voltage value or current value may be performed, for example, based at least in part on one or more attributes of the pixels (e.g., an array, such as an RGB stripe or a pentile structure, of the pixels, or the size of each subpixel). At least some pixels of the display 210 may be driven, for example, based at least in part on the voltage value or the current value such that visual information (e.g., a text, an image, or an icon) corresponding to the image data may be displayed via the display 210.

The touch circuitry 250 may provide input information (e.g., a position, an area, a pressure, or a time) indicative of the touch input or the hovering input detected via the touch sensor 251 to the processor 120. According to an embodiment, at least part (e.g., the touch sensor IC 253) of the touch circuitry 250 may be formed as part of the display 210 or the DDI 230, or as part of another component (e.g., the auxiliary processor 123) disposed outside the display module 160.

In such a case, the at least one sensor or the control circuit for the at least one sensor may be embedded in one portion of a component (e.g., the display 210, the DDI 230, or the touch circuitry 250) of the display module 160. For example, when the sensor module 176 embedded in the display module 160 includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) corresponding to a touch input received via a portion of the display 210. As another example, when the sensor module 176 embedded in the display module 160 includes a pressure sensor, the pressure sensor may obtain pressure information corresponding to a touch input received via a partial or whole area of the display 210. According to an embodiment, the touch sensor 251 or the sensor module 176 may be disposed between pixels in a pixel layer of the display 210, or over or under the pixel layer.

The voice recognition manager 327, for example, may transmit a user's voice data to the server 108, and receive, from the server 108, a command corresponding to a function to be executed on the electronic device 101 based at least in part on the voice data, or text data converted based at least in part on the voice data. According to an embodiment, the middleware 144 may dynamically delete some existing components or add new components. According to an embodiment, at least part of the middleware 144 may be included as part of the OS 142 or may be implemented as another software separate from the OS 142.

The device management application, additionally or alternatively, may support installation, delete, or update of an application running on the external electronic device.

[0073] FIG. 4 is a diagram showing a first state of an electronic device according to an embodiment of the disclosure.

[0074] FIG. 5 is a diagram showing a second state of an electronic device according to an embodiment of the disclosure.

[0075] Referring to FIGS. 4 and 5, an electronic device 400 (e.g., the electronic device 101 in FIG. 1) according to one embodiment may include a housing and a display 450. The housing may include a first structure 410 and a second structure 440.

[0076] In one embodiment, the electronic device 400 may be of a slidable type or a rollable type. The electronic device 400 may include the first state (e.g., a closed state or a retracted state) and the second state (e.g., an opened state or an extended state). The first state and the second state may be determined based on a relative position of the second structure 440 with respect to the first structure 410. The electronic device 400 may be deformable into between the first state and the second state via a user's manipulation or a mechanical operation.

[0077] In one embodiment, the first state may refer to a state in which an area (or a size) of the display 450 visually exposed in a frontward direction of the electronic device 400 is relatively reduced. The second state may refer to a state in which the area (or the size) of the display 450 exposed in a frontward direction of the electronic device 400 is relatively enlarged. For example, the second state may be a state in which the area of the display 450 visually exposed in a frontward direction of the electronic device 400 is larger than that in the first state. Further, in the first state, a portion (e.g., side portions 443 and 444 respectively facing in +y/−y axis directions) of the second structure 440 may be located inwardly (or outwardly) of the first structure 410, such that the second structure 440 may be in a closed state with respect to the first structure 410. In the second state, the portions 443 and 444 of the second structure 440 exit from the first structure 410 such that the second structure 440 may be in an opened state with respect to the first structure 410. In one embodiment, the electronic device 400 may further include a third state (hereinafter, also referred to as an intermediate state) between the first state and the second state. For example, the intermediate state may have a larger area of the display 450 that is visually exposed in a frontward direction of the electronic device 400 compared to that in the first state, and a smaller area of the display 450 that is visually exposed in a frontward direction of the electronic device 400 compared to that in the second state.

[0078] In one embodiment, the first structure 410 and the second structure 440 may be coupled to each other such that the first structure 410 and the second structure 440 slides relative to each other. The second structure 440 may be slidably coupled to one side of the first structure 410. For example, the first structure 410 may be a fixed structure, and the second structure 440 may be a structure that is relatively movable with respect to the first structure 410. The second structure 440 may be coupled to one side of the first structure 410 so as to be slidable in both directions (e.g., +x/−x axis directions) with respect to the first structure 410.

[0079] In another embodiment, a long side surface (e.g., a surface extending in the y-axis direction) of the second structure 440 may slide in both directions (e.g., the +y/−y-axis directions). In still another embodiment, the electronic device 400 includes a plurality of second structures 440. One second structure may slide in one direction (e.g., +x-axis direction or +y-axis direction), and the other second structure may slide in the opposite direction (e.g., −x-axis direction or −y-axis direction).

[0080] In one embodiment, the electronic device 400 may be deformed into the first state and the second state as the second structure 440 slides with respect to the first structure 410. For example, in the electronic device 400, the second structure 440 may move in a second direction DR2 with respect to the first structure 410 in the first state (e.g., the state of FIG. 4) such that the electronic device 400 may be deformed into the second state (e.g., the state of FIG. 5). Conversely, the second structure 440 may move in a first direction DR1 with respect to the first structure 410 in the second state such that the electronic device 400 may be deformed into the first state.

[0081] In one embodiment, the display 450 may change the size (or the area) of the area thereof exposed in a frontward direction of the electronic device 400 in response to the sliding operation of the second structure 440. While the display 450 is supported on at least one of the first structure 410 or the second structure 440, a size of the exposed area thereof may increase or decrease according to the sliding operation of the second structure 440. The display 450 may include at least a partially flexible part.

[0082] In one embodiment, the display 450 may include a basic area AA1 and an extended area AA2 extending from the basic area AA1. The basic area AA1 may be maintained at a state exposed in a frontward direction of the electronic device 400. The extended area AA2 may have a variable size of an area exposed in a frontward direction of the electronic device 400 according to the state of the electronic device 400. The extended area AA2 may extend from one side of the basic area AA1. For example, the basic area AA1 may mean a partial area of the display 450 visually exposed in a frontward direction of the electronic device 400 in the first state. The extended area AA2 may be refer to an area which is located inside the electronic device 400 in the first state, and whose at least a portion extends out of the electronic device 400 and is visually exposed in a frontward direction of the electronic device 400 in the second state.

[0083] In one embodiment, in the first state, the basic area AA1 may be located across a front surface of the electronic device 400, and the extended area AA2 may be located inside the first structure 410. The second state may refer to a state in which at least a portion of the extended area AA2 together with the basic area AA1 are located across the front surface of the electronic device 400. In the electronic device 400, the extended area AA2 is additionally exposed in a frontward direction of the electronic device 400 in the second state, so that a size of the exposed area of the display 450 may increase. The display 450 may include a display area which is visually exposed in a frontward direction of the electronic device 400 and in which predetermined visual information (or screen) is displayed. For example, in the first state, the display area may correspond to the basic area AA1. In the second state, the display area may correspond to a sum of a portion of the extended area AA2 and the basic area AA1. In the second state, the electronic device 400 may provide an extended display area larger than that in the first state as the screen may be displayed on the portion of the extended area AA2 together with the basic area AA1 in the second state.

[0084] In one embodiment, the electronic device 400 may be manually switched to the first state and/or the second state by the user or a driving mechanism (e.g., a drive motor, a reduction gear module and/or a gear assembly) disposed inside the first structure 410 or the second structure 440. According to one embodiment, an operation of the driving mechanism may be triggered based on user input. According to one embodiment, the user input for triggering the operation of the driving mechanism may include a touch input, a force touch input, and/or a gesture input on the display 450. In another embodiment, the user input for triggering the operation of the driving mechanism may include a voice input, or an input to a physical button disposed on an outer face of the first structure 410 and/or the second structure 440 and exposed outwardly.

[0085] FIG. 6 is an exploded perspective view of an electronic device according to an embodiment of the disclosure.

[0086] Referring to FIG. 6, an electronic device 600 according to one embodiment may include a housing composed of a first structure 610 and a second structure 640, a display 650, a first roller 691, a second roller 692, a tension belt 693, and a circuit board 694.

[0087] In one embodiment, the first structure 610 may include a casing 620 and a bracket 630. The bracket 630 may be coupled to the casing 620, and at least a portion thereof may be surrounded with the casing 620. For example, the bracket 630 may be fixed to the casing 620. The casing 620 and the bracket 630 may be movable relative to the second structure 640 in response to a sliding operation of the second structure 640. The casing 620 and the bracket 630 may act as a reference for sliding movement of the second structure 640 and the display 650.

[0088] In one embodiment, the casing 620 may define at least a portion of an outer surface of the electronic device 600. The casing 620 may include a first side member 621, a second side member 622, and a rear member 623. The first side member 621 and the second side member 622 may face toward each other in a direction substantially perpendicular to a sliding direction (e.g., the first direction DR1 and the second direction DR2) of the second structure 640. The rear member 623 may be disposed between the first side member 621 and the second side member 622, and may be connected to each of the first side member 621 and the second side member 622. The first side member 621, the second side member 622, and the rear member 623 may be coupled to each other to define a space in which at least some of other components (e.g., the bracket 630, the second structure 640, and the circuit board 694) of the electronic device 600 may be disposed.

[0089] In one embodiment, the rear member 623 may include a frame 624 and a cover 625. For example, the frame 624 may be coupled to the bracket 630. The cover 625 may be coupled to the frame 624 to form at least a portion of the rear surface of the electronic device 600. A space in which the second structure 640 and the extended area AA2 of the display 650 are accommodated may be located between the cover 625 and the bracket 630.

[0090] According to the illustrated embodiment, the first side member 621, the second side member 622, the frame 624 and/or the rear cover 625 may be formed as separate components, and may be assembled with each other or may be combined with each other. However, the disclosure is not limited thereto. According to various embodiments of the disclosure, the first side member 621, the second side member 622, the frame 624 and the rear cover 625 are integrally formed with each other to constitute one part.

[0091] In one embodiment, the bracket 630 may be disposed to at least partially overlap the second structure 640. A first surface 631 (e.g., a surface facing in the +z-axis direction or a top surface based on FIG. 6) of the bracket 630 may face toward the plate portion 641 of the second structure 640. A second surface 632 (e.g., a surface facing in the −z-axis direction or a bottom surface based on FIG. 6) of the bracket 630 may face toward the circuit board 694. The circuit board 694 may be disposed on the second surface 632 of the bracket 630.

[0092] In one embodiment, the second structure 640 may be disposed to surround at least a portion of the bracket 630. The second structure 640 may include the plate portion 641 supporting a portion of the basic area AA1 of the display 650 and a multi-joint member 642 that supports another portion of the basic area AA1 and a portion of the extended area AA2 of the flexible display (i.e., display 650). For example, the multi-joint member 642 may extend from the plate portion 641, and may be bendable. The multi joint member 642 may be at least partially curved in response to the sliding operation of the second structure 640.

[0093] In one embodiment, the multi joint member 642 may be coupled to the first roller 691. The multi joint member 642 may include a plurality of bars extending in a direction substantially parallel to a rolling axis R of the first roller 691. For example, the multi joint member 642 may include a flexible track or a hinge rail. According to one embodiment, the plate portion 641 may be configured to slide in the first direction DR1 or the second direction DR2. The multi joint member 642 may be configured such that a portion thereof rotates via the first roller 691 and the other portion thereof slides in the first direction DR1 or the second direction DR2.

[0094] In one embodiment, the first roller 691 may be disposed on one side surface of the bracket 630. The first roller 691 may be rotatably coupled to the bracket 630. For example, the first roller 691 may rotate in both directions about the rolling axis R according to the sliding operation of the second structure 640. The first roller 691 may contact a portion of the multi joint member 642 of the second structure 640. For example, the second structure 640 may be disposed such that the multi joint member 642 surrounds at least a portion of the first roller 691. The first roller 691 may be configured to rotate a portion of the multi joint member 642. The first roller 691 may contact an area of the multi joint member 642 varying according to the state change of the electronic device 600.

[0095] In one embodiment, the second structure 640 may be slidably coupled to the bracket 630 via the tension belt 693 and the second roller 692. The tension belt 693 may connect an end of the plate portion 641 of the second structure 640 and an end of the multi-joint member 642 to each other. The second roller 692 may be configured to rotate in the same direction as a rotation direction of the first roller 691 according to the sliding operation of the second structure 640. For example, the tension belt 693 may be configured to provide tension to the multi joint member 642 while being disposed between the plate portion 641 and the multi joint member 642. According to one embodiment, when the plate portion 641 moves in the first direction DR1, one end of the tension belt 693 connected to the plate portion 641 may move in the first direction DR1, while the opposite end of the tension belt 693 connected to the multi-joint member 642 may move in the second direction DR2. Conversely, when the plate portion 641 moves in the second direction DR2, one end of the tension belt 693 may move in the second direction DR2, while the opposite end of the tension belt 693 may move in the first direction DR1. However, the illustrated embodiment is illustrative. According to various embodiments, the electronic device 600 may not include at least one of the second roller 692 or the tension belt 693.

[0096] In one embodiment, the display 650 may be disposed on the second structure 640. For example, the display 650 may be coupled to the second structure 640 such that the display 650 together with the second structure 640 perform sliding movement with respect to the first structure 610. The display 650 may include the basic area AA1 and the extended area AA2 extending from the basic area AA1. For example, the basic area AA1 may mean an area visually exposed in a frontward direction of the electronic device 600 in the first state. The extended area AA2 may refer to an area which may be located inside the electronic device 600 in the first state, and whose at least a portion moves out of the electronic device 600 and thus is visually exposed in a frontward direction of the electronic device 600 in the second state.

[0097] The electronic device 600 according to an embodiment may be configured such that in the first state, the basic area AA1 may be visually exposed in a frontward direction of the electronic device 600, and in the second state, at least a portion of the extended area AA2 together with the basic area AA1 may be visually exposed in a frontward direction of the electronic device 600. A position of the extended area AA2 may vary as at least a portion thereof rotates together with the rotation of the first roller 691. For example, as the second structure 640 moves in the first direction DR1 with respect to the first structure 610, the extended area AA2 together with the basic area AA1 may be disposed on the front surface of the electronic device 600. Further, the extended area AA2 may be accommodated in a space between the bracket 630 and the rear member 623 as the second structure 640 moves in the second direction DR2 with respect to the first structure 610.

[0098] In one embodiment, the circuit board 694 may be disposed in the first structure 610. The circuit board 694 may be disposed between the bracket 630 and the rear member 623. For example, the circuit board 694 may be disposed inside the electronic device 600 while being supported on the bracket 630. The circuit board 694 may be coupled to at least a partial area of the second surface 632 of the bracket 630 and thus may be fixed to the first structure 610. The circuit board 694 together with the first structure 610 may move relative to the second structure 640 during the sliding operation of the second structure 640.

[0099] In one embodiment, the circuit board 694 may include a printed circuit board (PCB), a flexible PCB (FPCB), or a rigid-flexible PCB (RFPCB). Various electronic components included in the electronic device 600 may be electrically connected to the circuit board 694. A processor (e.g., the processor 120 in FIG. 1), a memory (e.g., the memory 130 in FIG. 1) and/or an interface (e.g., the interface 177 in FIG. 1) may be disposed in the circuit board 694). For example, the processor may include a main the processor and/or an auxiliary processor. The main the processor and/or the auxiliary processor may include one or more of a central processing unit, an application the processor, a graphics processing unit, and an image signal processor, a sensor hub processor or a communication processor. For example, the memory may include a volatile memory or a non-volatile memory. For example, the interface may include a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and/or an audio interface. Further, the interface may electrically or physically connect the electronic device 600 to an external electronic device, and may include a USB connector, an SD card/MMC connector, or an audio connector.

[0100] In one embodiment, a battery (e.g., the battery 189 in FIG. 1) may supply power to at least one component of the electronic device 600. The battery may be integrally disposed inside the electronic device 600 or may be disposed detachably from the electronic device 600. According to various embodiments of the disclosure, the battery may be disposed inside the electronic device 600 while the battery together with the circuit board 694 are supported on the bracket 630. The battery may be coupled to at least a partial area of the second surface 632 of the bracket 630. The battery may be substantially coplanar with the circuit board 694. The battery together with the first structure 610 may move relative to the second structure 640 during the sliding operation of the second structure 640.

[0101] FIG. 7 is a block diagram showing an electronic device according to an embodiment of the disclosure.

[0102] Referring to FIG. 7, an electronic device 700 according to one embodiment (e.g., the electronic device 101 in FIG. 1) may include a display 710 (e.g., the display module 160 in FIG. 1), a memory 730 (e.g., the memory 130 in FIG. 1) and a processor 720 (e.g., the processor 120 in FIG. 1).

[0103] At least a portion of the display 710 may include a flexible area. According to one embodiment, the display 710 may be configured to extend and retract. For example, the display 710 may include at least one of a slideable display, a foldable display, or a rollable display.

[0104] Depending on the state of the electronic device 700, a size of the display area (or the exposed area) of the display 710 may increase or decrease. In the first state (e.g., the retracted state) of the electronic device 700, the display area of the display 710 may retract, and in the second state (e.g., the extended state), the display area of the display 710 may extend. For example, in the first state of the electronic device 700, at least a portion of the display 710 may be disposed in a rolled or bent state and within the electronic device 700, and thus may not be visually exposed. In the second state of the electronic device 700, the at least a portion of the display 710 may be unfolded and thus visually exposed.

[0105] According to one embodiment, the display 710 may extend or retract in an automatic, semi-automatic, or manual manner. For example, the display 710 may further receive a driving motor (not shown) therein. The automatic display 710 may automatically extend or retract using the driving motor based on a specified signal created by the processor 720. For example, in the semi-automatic manner, the display 710 of the electronic device 700 may automatically extend based on an operation of the drive motor based on a specified signal created by the processor 720. Then, the display 710 of the electronic device 700 may retract by a user directly applying a force to the display 710 of the electronic device 700 in the extended state. For example, in the manual manner, the display 710 of the electronic device 700 may extend or retract by a user directly applying a force to the display 710 of the electronic device 700. The display as described with reference to the drawings to be described later may extend or retract in the above-described automatic, semi-automatic, or manual manner. In another example, the display 710 may extend based on an input applied to a pre-specified area. When an input provided from the user (e.g., an input based on a physical key, a touch input, a long press input, or an input of a specified pattern (e.g., knocks)) is applied to a predetermined area of the display 710 in the state in which the display 710 has retracted, the display 710 may automatically extend. In various embodiments, the display 710 may extend when an input provided from an external input device (not shown) (e.g., a stylus pen) is applied to a predetermined area in the state in which the display 710 has retracted.

[0106] The memory 730 may store therein at least one program, at least one application, data, or instructions executed by the processor 720. According to one embodiment, the memory 730 may include at least a portion of the memory 130 shown in FIG. 1. According to one embodiment, the memory 730 may store therein information or instructions for performing at least a portion of an operation of the electronic device 700 to be described later. According to one embodiment, the memory 730 may store therein instructions related to a plurality of applications executed by the processor 720.

[0107] The processor 720 may detect the state of the electronic device 700 using a sensor (e.g., the sensor module 176 of FIG. 1). For example, the sensor may be at least one of a magnetic sensor such as a hall sensor, a proximity sensor, an illuminance sensor, a touch sensor, a bending sensor, and an infrared sensor, or a combination thereof. For example, the processor 720 may identify a rolling state or a sliding state of the display 710. The processor 720 may identify rolling in/out (or sliding in/out) and a rolling amount (or a sliding amount). According to an embodiment, the processor 720 may acquire state information about the state of the electronic device 700 from the sensor.

[0108] According to one embodiment, in order to detect the state of the electronic device 700, the processor 720 may include another sensor for checking movement (rotation) of a magnetic body (e.g., in the x-axis, y-axis, and z-axis directions). For example, the electronic device 700 may include a TMR sensor (a tunnel magneto-resistance sensor) and thus may use a resistance value that changes based on relative angles between a plurality of magnetic units of the TMR sensor to check movement (rotation) of the magnetic body. Further, according to another embodiment, the electronic device 700 may check the movement (rotation) of the magnetic body using an anisotropic magneto-resistance (AMR) sensor or a giant magneto-resistance (GMR) sensor.

[0109] In one embodiment, the sensor may include at least one of an accelerometer, a gyro sensor (e.g., a gyroscope), and a geomagnetic sensor. Alternatively, the sensor may detect an inclination angle of the electronic device 700 with respect to a ground surface and/or a direction in which the electronic device 700 faces in a three-dimensional coordinate system, using sensed data acquired from at least one of the accelerometer, the gyro sensor or the geomagnetic sensor. However, the disclosure is not limited thereto. Various sensors capable of obtaining information about the inclination angle of the electronic device 700 may be used. For example, the accelerometer may sense information about linear motion of the electronic device 700 and/or acceleration of the electronic device 700 in three axes. The gyro sensor may sense information related to the rotation of the electronic device 700, and the geomagnetic sensor may sense information about a direction in which the electronic device 700 faces in an absolute coordinate system.

[0110] According to one embodiment, the processor 720 may create a virtual coordinate space based on an azimuth (e.g., a yaw, pitch and/or roll value) as measured by a 9-axis motion sensor (e.g., the accelerometer, the gyro sensor, and the geomagnetic sensor). The processor 720 may define one area of the virtual coordinate space as a landscape range, and another area thereof as a portrait range. According to one embodiment, when a current state of the electronic device 700 is included in the landscape range, the processor 720 may determine that the electronic device 700 has a landscape orientation. For example, the landscape orientation of the electronic device 700 may represent a state in which parallel long sides of the electronic device 700 are parallel to a horizontal axis parallel to the ground. According to one embodiment, when the current state of the electronic device 700 is included in the portrait range, the processor 720 may determine that the electronic device 700 has a portrait orientation. For example, the portrait orientation of the electronic device 700 may represent a state in which the parallel long sides of the electronic device 700 are parallel to a vertical axis perpendicular to the ground.

[0111] The processor 720 may display a preview image for a background screen on the display 710 in response to execution of an application for setting the background screen. The processor 720 may display a preview image for a background screen using a selected image based on a user input for selecting one image. According to one implementation, the processor 720 may sequentially (or successively) display areas corresponding to background screens respectively in at least two states of the electronic device 700 in the selected image as a preview image on the display 710. For example, the processor 720 may successively display an area of an image to be displayed as a background screen in a detected current state of the electronic device 700 and an area of an image to be displayed as a background screen in another state different from the current state as a preview image on the display 710.

[0112] When the detected state of the electronic device 700 is the first state, the processor 720 may sequentially (or successively) display a first preview image corresponding to preview for a background screen in the first state and a second preview image corresponding to preview for a background screen in the second state on the display 710 which is in the first state. The first preview image may include a first area of the selected image. The first area may be specified by a user input. The second preview image may include a second area of the selected image. The processor 720 may specify the second area in the selected image based on the specified first area. The processor 720 may specify the first area and the second area including the first area and one area (e.g., a third area) adjacent to the first area. For example, when the detected state of the electronic device 700 is the first state, the processor 720 may display the first area of the selected image as a preview image, and then display the second area including the first area of the image and one area (e.g., the third area) adjacent to the first area as a preview image on the display 710. The processor 720 may change display attribute (e.g., transparency, saturation, or brightness) of at least a portion of the second preview image.

[0113] When the detected state of the electronic device 700 is the second state, the processor 720 may sequentially (or successively) display a third preview image corresponding to the second state and a fourth preview image corresponding to the first state on the display 710 which is in the second state. The third preview image may include a fourth area of the selected image. The fourth area may be specified by a user input. The fourth preview image may include a fifth area of the selected image. The processor 720 may specify a fifth area in the selected image based on the specified fourth area. The processor 720 may specify one area in the fourth area as the fifth area. For example, when the detected state of the electronic device 700 is the second state, the processor 720 may display the fourth area of the selected image as a preview image, and then display the fifth area as one area within the fourth area of the image as a preview image. The processor 720 may change display attribute (e.g., transparency, saturation, or brightness) of the fourth preview image. According to one embodiment, the third preview image may be substantially identical to the second preview image, and the fourth preview image may be substantially identical to the first preview image. For example, the fourth area of the image may be substantially equal to the second area of the image, while the fifth area of the image may be substantially equal to the first area of the image.

[0114] The processor 720 may detect a state change of the electronic device 700. When the processor 720 detects a state change of the electronic device 700, the processor 720 may change and display a preview image in a corresponding manner to the state change of the electronic device 700 on the display 710. For example, when the extended state of the electronic device 700 is detected, the processor 720 may extend and display the first area in the first preview image or the second preview image in proportion to the extension of the display area of the display 710. In another example, when the retracted state of the electronic device 700 is detected, the electronic device 700 may reduce and display the third preview image in proportion to the reduction of the display area of the display 710.

[0115] Hereinafter, with reference to FIG. 8, an electronic device according to one embodiment will be described.

[0116] FIG. 8 is a diagram illustrating the electronic device 800 that displays preview images 820 and 830 according to an embodiment of the disclosure. Hereinafter, an operation of the electronic device 800 may be referred to as an operation of a processor (e.g., the processor 120 in FIG. 1).

[0117] Referring to FIG. 8, the electronic device 800 according to one embodiment may display the preview images 820 and 830 for a background screen to be set based on a specified image on a display 810. The specified image may be an image selected by a user input for selecting an image. For example, the electronic device 800 may display the preview images 820 and 830 for the background screen on the display 810 in response to execution of a background screen setting application. According to one embodiment, the electronic device 800 may display a changed (or replaced) image as the preview images 820 and 830 based on a user input (e.g., a user input for an image replacement icon).

[0118] When the electronic device 800 according to one embodiment is in the first state (e.g., the retracted state), the electronic device 800 may display the first preview image 820 corresponding to a background screen in the first state state) and the second preview image 830 corresponding to a background screen corresponding to the second state (e.g., the extended state) the display 810 which is in the first state. The electronic device 800 according to one embodiment may display sequentially (or successively) one and the other of the first preview image 820 and the second preview image 830 based on a current state of the electronic device 800. The electronic device 800 according to one embodiment may display sequentially the first preview image 820 and the second preview image 830 when the current state of the electronic device 800 is the first state. For example, the electronic device 800 may display the first preview image 820 for a specified time duration and then display the second preview image 830 on the display 810 which is in the first state. In another example, the electronic device 800 may alternately display the first preview image 820 and the second preview image 830 on the display 810. According to one embodiment, the electronic device 800 may display sequentially (or successively) the first preview image 820 and the second preview images 830 on the display 810, based on a user input (e.g., touch, swipe) to one user interface (e.g., an icon for background screen setting).

[0119] The first preview image 820 may correspond to a background screen displayed in the first state of the electronic device 800. An aspect ratio of the first preview image 820 may correspond to an aspect ratio of a reduced display area of the display 810 visually exposed in the first state of the electronic device 800. The first preview image 820 may include at least one area of an image. For example, the first preview image 820 may include a first area 861 of the image. The first area 861 may be specified (or changed) based on a user input (e.g., touch, swipe).

[0120] The second preview image 830 may correspond to a background screen displayed in the second state of the electronic device 800. The aspect ratio of the second preview image 830 may correspond to an aspect ratio of an enlarged display area of the display 810 visually exposed in the second state of the electronic device 800. The second preview image 830 may include the first area 861 of the image and at least one area adjacent to the first area 861. According to one embodiment, the second preview image 830 may include the first area 861 of the image and one area of the image adjacent to the first area 861 of the image in an extending direction (e.g., +x direction) of the display 810 in the second state of the electronic device 800. For example, the second preview image 830 may include a second area 862 composed of the first area 861 of the image, and a third area 863 adjacent to the first area 861. The display 810 of the electronic device 800 may extend in one direction (e.g., +x direction). In this case, the electronic device 800 may specify the first area 861 of the image and the third area 863 of the image adjacent to the first area 861 in the extending direction (e.g., the +x direction) as the second area 862. However, the extending direction of the display 810 is not limited as shown in FIG. 8. For example, the display 810 may extend in the −x direction or the y direction. In another example, the display 810 may extend in multiple directions.

[0121] The electronic device 800 may apply a specified effect when the first preview image 820 has been switched to the second preview image 830. For example, the electronic device 800 may display the first area 861 of the image, and may display the third area 863 of the image in addition to the first area 861 such that the third area 863 gradually appears in the extending direction (e.g., +x direction). The electronic device 800 according to one embodiment may use the display 810 to set the display attribute (e.g., transparency, saturation or brightness) of at least a portion of the second area 862 of the image in the second preview image 830 to be different from that of a remaining portion of the second area 862. The electronic device 800 may display the first area 861 of the image based on first display attribute, and display the third area 863 based on second display attribute that is at least partially different from the first display attribute. The electronic device 800 according to one embodiment may display the image such that the transparency of the third area 863 is higher than that of the first area 861. For example, the electronic device 800 may set the transparency of the first area 861 of the image to 0% and the transparency of the third area 863 to 50% and display the first and third areas on the display 810. When the electronic device 800 which is in the first state displays the second preview image 830 corresponding to the second state, the electronic device 800 may set the display attribute of the first area 861 and the display attribute of the third area 863 to be different from each other. Thus, an image area (e.g., the third area 863) that is additionally displayed when the display 810 extends may be intuitively identified by the user.

[0122] The electronic device 800 according to an embodiment may display a user interface (i.e., first icon 851, and first information 852) related to the background screen setting. For example, the user interface (i.e., first icon 851, and first information 852) may include a first icon 851 and first information 852 for background screen setting. For example, the first information 852 may include “Set a background screen in consideration of a to-be-slidably-extended range”. The user interface (i.e., first icon 851, and first information 852) shown in FIG. 8 is only example. The disclosure is not limited to the illustrated example.

[0123] When receiving a user input to the first icon 851 from the user, the electronic device 800 may specify (or set) an image selected based on the first preview image 820 and the second preview image 830 as a background screen of the electronic device 800. For example, the electronic device 800 may set the background screen in the first state in response to selection of the first preview image 820 and set the background screen in the second state in response to selection of the second preview image 830. When the background screen has been set by the user input to the first icon 851, the electronic device 800 may display the background screen corresponding to the first preview image 820 on the display 810 which in in the retracted state, and may display the background screen corresponding to the second preview image 830 on the display 810 which in in the extended state.

[0124] FIG. 9 shows a first area 911 (e.g., the first area 861 of FIG. 8) of an image 910 included in a first preview image (e.g., the first preview image 820 of FIG. 8), and a second area 912 (e.g., the second area 862 of FIG. 8) of the image 910 included in a second preview image (e.g., the second preview image 830 of FIG. 8) in an electronic device (e.g., the electronic device 800 of FIG. 8) according to one embodiment.

[0125] Referring to FIG. 9, the electronic device which is in the first state (e.g., the retracted state) may specify one area of the image 910 as the first area 911 based on a user input (or execution of a background screen setting application).

[0126] The electronic device may specify the second area 912 of the image 910 based on the first area 911. For example, the electronic device may specify the first area 911 and the third area 913 adjacent to the first area 911 in one direction (e.g., +x direction) as the second area 912. However, a location of the third area 913 shown in FIG. 9 is only an example. The disclosure is not limited thereto. The location of the third area 913 may be determined based on the extending direction of the display of the electronic device. For example, the electronic device may specify the first area 911 and an area adjacent to the first area 911 in another direction (e.g., −x direction or y direction) as the third area 913.

[0127] Hereinafter, with reference to FIG. 10, an electronic device according to one embodiment will be described.

[0128] FIG. 10 is a diagram showing the electronic device that displays a preview image according to an embodiment of the disclosure. Hereinafter, an operation of the electronic device may be referred to as an operation of a processor (e.g., the processor 120 in FIG. 1).

[0129] Referring to FIG. 10, an electronic device 1000 according to one embodiment may display preview images 1020 and 1030 on the display 1010. For example, the electronic device 1000 may display the preview images 1020 and 1030 for the background screen on the display 1010 in response to execution of the background screen setting application. According to one embodiment, the electronic device 1000 may display a changed (or replaced) image as the preview images 1020 and 1030 based on a user input (e.g., user input to an image replacement icon).

[0130] While the electronic device 1000 according to an embodiment is in the second state (e.g., the extended state), the electronic device 1000 may display a third preview image 1020 corresponding to the background screen in the second state and a fourth preview image 1030 corresponding to the background screen in the first state (e.g., the retracted state) on the display 1010. The third preview image 1020 may be substantially identical to the second preview image 830 of FIG. 8, while the fourth preview image 1030 may be substantially identical to the first preview image 820 of FIG. 8. The electronic device 1000 according to one embodiment may display sequentially (or successively) one and the other of the third preview image 1020 and the fourth preview image 1030 based on a current state of the electronic device 1000. The electronic device 1000 according to one embodiment may sequentially display the third preview image 1020 and the fourth preview image 1030 when the current state of the electronic device 1000 is the second state. For example, the electronic device 1000 may display the third preview image 1020 for a specified time duration and then display the fourth preview image 1030 on the display 1010 which is in the second state. In another example, the electronic device 1000 may alternately display the third preview image 1020 and the fourth preview image 1030 on the display 1010. According to one embodiment, the electronic device 1000 may display sequentially (or successively) the third preview image 1020 and the fourth preview image (1030) on the display 1010, based on the user input (e.g., touch, swipe) to an icon (e.g., an icon for background screen setting).

[0131] The third preview image 1020 may correspond to a background screen displayed in the second state of the electronic device 1000. An aspect ratio of the third preview image 1020 may correspond to an aspect ratio of an extended display area of the display 1010 visually exposed in the second state of the electronic device 1000. The third preview image 1020 may include at least one area of the image. For example, the third preview image 1020 may include a fourth area 1061 of the image. The fourth area 1061 may be substantially the same as the second area 862 of FIG. 8. The fourth area 1061 may be specified (or changed) by a user input (e.g., touch, swipe).

[0132] The fourth preview image 1030 may correspond to a background screen displayed in the first state of the electronic device 1000. An aspect ratio of the fourth preview image 1030 may correspond to an aspect ratio of the reduced display area of the display 1010 visually exposed in the first state of the electronic device 1000. The fourth preview image 1030 may include a fifth area 1062 of the image. The fifth area 1062 may be substantially the same as the first area 861 of FIG. 8. The fifth area 1062 of the image may be included in one area within the fourth area 1061. According to one embodiment, the fourth area 1061 may further include one area of the image adjacent to the fifth area 1062 of the image in the extending direction (e.g., +x direction) of the display 1010.

[0133] The electronic device 1000 may apply a specified effect when the device switches the third preview image 1020 to the fourth preview image 1030. For example, the electronic device 1000 may display the fourth area 1061 of the image, and then may display the fifth area 1062 such that an area of the fourth area 1061 other than fifth area 1062 gradually disappears in a retracting direction (e.g., −x direction).

[0134] The electronic device 1000 according to an embodiment may change the display attribute (e.g., transparency, saturation or brightness) of the fourth preview image 1030, and may display the fourth preview image 1030 to which the changed display attribute is applied on the display 1010. The electronic device 1000 may display the third preview image 1020 based on first display attribute, and display the fourth preview image 1030 based on second display attribute which is at least partially different from the first display attribute. The electronic device 1000 according to one embodiment may display the fourth preview image 1030 at transparency higher than transparency of the third preview image 1020. For example, the electronic device 1000 may set the transparency of the third preview image 1020 to 0% and set the transparency of the fourth preview image 1030 to 50% and display the same on the display 1010.

[0135] The electronic device 1000 according to an embodiment may display a user interface (i.e., first icon 1051, and first information 1052) related to background screen setting. For example, the user interface (i.e., first icon 1051, and first information 1052) may include a first icon 1051 and first information 1052 for background screen setting. For example, the first information 1052 may include “Set a background screen in consideration of a to-be-slidably-retracted range”. The user interface 1051 and 1052 shown in FIG. 10 is only an example. The disclosure is not limited to the illustrated example.

[0136] Upon receiving the user input to the first icon 1051 from the user, the electronic device 1000 may specify (set) an image selected based on the third preview image 1020 and the fourth preview image 1030 as the background screen of the electronic device 1000. For example, the electronic device 1000 may set the background screen in the second state in response to selection of the third preview image 1020 and set the background screen in the first state in response to selection of the fourth preview image 1030. When the background screen has been set by the user input to the first icon 1051, the electronic device 1000 may display a background screen corresponding to the third preview image 1020 on the display 1010 which in in the extended state, and a background screen corresponding to the fourth preview image 1030 on the display 1010 which is in the retracted state.

[0137] FIG. 11 shows a fourth area 1111 (e.g., the fourth area 1061 of FIG. 10) of an image 1110 included in a third preview image (e.g., the third preview image 1020 of FIG. 10), and a fifth area 1112 (e.g., the fifth area 1062 of FIG. 10) of the image 1110 included in a fourth preview image (e.g., the fourth preview image 1030 of FIG. 10) in an electronic device (e.g., the electronic device (1000) of FIG. 10) according to an embodiment of the disclosure.

[0138] Referring to FIG. 11, the electronic device which is in the second state (e.g., the extended state) may specify one area of an image 1110 as a fourth area 1111 based on a user input (or execution of a background screen setting application).

[0139] The electronic device may specify a fifth area 1112 of the image 1110 based on the fourth area 1111. The electronic device may specify a partial area of the fourth area 1111 in the image as the fifth area 1112. A location of the fifth area 1112 in the fourth area 1111 may be determined based on the retracting direction of the display of the electronic device. For example, the electronic device may specify one area located in the retracting direction (e.g., −x direction) of the display in the fourth area 1111 of the image as the fifth area 1112 and specify one area located in the extending direction (e.g., +x direction) of the display in the fourth area 1111 of the image as the sixth area 1113. For example, the fourth area 1111 of the image may include the fifth area 1112 and the sixth area 1113 adjacent to the fifth area 1112. However, positions of the fourth area 1111 and the fifth area 1112 shown in FIG. 11 are only examples. The disclosure is not limited thereto.

[0140] Hereinafter, with reference to FIG. 12, an electronic device according to one embodiment will be described.

[0141] FIG. 12 is a view showing a preview image according to a state of the electronic device according to an embodiment of the disclosure.

[0142] Referring to FIG. 12, a state of the electronic device 1200 according to an embodiment may include a first state 1201 (e.g., a retracted state) in which the display 1210 has retracted, the second state 1203 in which the display 1210 has extended (e.g., an extended state) and a third state 1202 (e.g., an intermediate state) in which a portion of the display 1210 has retracted or extended. As the state of the electronic device 1200 is gradually changed to the first state 1201, the third state 1202, and the second state 1203, the display area of the display 1210 may be gradually enlarged.

[0143] The electronic device 1200 of the first state 1201 may display a preview image 1220 (e.g., the second preview image 830 of FIG. 8) on the display 1210. The preview image 1220 displayed on the display 1210 of the electronic device 1200 in the first state 1201 may include a second area 1222 including a first area 1221 of a selected image and a third area 1223 adjacent to the first area 1221 in an extending direction (e.g., +x direction) of the display 1210. The first area 1221 of the image displayed on the display 1210 of the electronic device 1200 in the first state 1201 may correspond to the background screen displayed in the first state 1201 of the electronic device 1200. The second area 1222 of the image may correspond to a background screen displayed in the second state 1203 of the electronic device 1200. An aspect ratio of the first area 1221 of the image may correspond to an aspect ratio of a display area of the display 1210 visually exposed in the first state 1201 of the electronic device 1200. An aspect ratio of the second area 1222 of the image may correspond to an aspect ratio of the enlarged display area of the display 1210 visually exposed in the second state 1203 of the electronic device 1200.

[0144] The electronic device 1200 which is in the first state 1201 may use the display 1210 to set display attribute (e.g., transparency, saturation, brightness of at least a portion of the second area 1222 of the image in the preview image 1220 to be different from that of a remaining portion thereof. The electronic device 1200 which is in the first state 1201 may display the first area 1221 of the image based on first display attribute, and may display the third area 1223 based on second display attribute which is at least partially different from the first display attribute. The electronic device 1200 according to one embodiment may set the transparency of the third area 1223 of the image to be higher than that of the first area 1221. For example, the electronic device 1200 may set the transparency of the first area 1221 of the image to 0% and the transparency of the third area 1223 to 50% and display the same on the display 1210. The electronic device 1200 according to one embodiment may extend and display an area displayed based on the display attribute in the preview image 1220 in proportion to the extension of the display area of the display 1210 as the state of the electronic device 1200 is changed from the first state 1201 to the second state 1203.

[0145] The electronic device 1200 of the third state 1202 may display a preview image 1230 on the display 1210. The preview image 1230 displayed on the display 1210 of the electronic device 1200 in the third state 1202 may include a second area 1222 including the sixth area 1224 of the selected image and a seventh area 1225 adjacent to the sixth area 1224 in the extending direction (e.g., +x direction) of the display 1210. In the preview image 1230 displayed on the display 1210 of the electronic device 1200 in the third state 1202, the sixth area 1224 may correspond to the background screen displayed when the third state 1202 is a current state of the electronic device 1200. The sixth area 1224 may include the first area 1221 and one area adjacent to the first area 1221 in the extending direction of the display 1210. The seventh area 1225 may be a remaining area except for the sixth area 1224 in the second area 1222.

[0146] The electronic device 1200 of the third state 1202 may display the sixth area 1224 of the image based on first display attribute, and display the seventh area 1225 based on second display attribute which is at least partially different from the first display attribute. The electronic device 1200 according to one embodiment may set the transparency of the seventh area 1225 of the image to be higher than that of the sixth area 1224. For example, the electronic device 1200 may set the transparency of the sixth area 1224 of the image to 0% and the transparency of the seventh area 1225 to 50% and display the same on the display 1210.

[0147] As the electronic device 1200 according to an embodiment is gradually changed to the first state 1201, the third state 1202 and the second state 1203, the electronic device 1200 may display the preview image 1230 in a corresponding manner to a varying state of the electronic device 1200. The electronic device 1200 may extend and display an area (e.g., the first area 1221 and the sixth area 1224) of the image displayed based on the first display attribute in proportion to the extension of the display 1210. As the display 1210 extends, the electronic device 1200 may reduce and display an area (e.g., the third area 1223 and the seventh area 1225) of the image displayed based on the second display attribute.

[0148] The electronic device 1200 which is in the second state 1203 may display the preview image 1240 (e.g., the third preview image 1020 in FIG. 10) corresponding to the background screen displayed in the second state 1203 on the display 1210.

[0149] As the electronic device 1200 according to one embodiment is gradually changed to the first state 1201, the third state 1202 and the second state 1203, the electronic device 1200 may display the preview images 1220, 1230, and 1240 in a corresponding manner to a varying state thereof. Thus the user may intuitively grasp the change of the background screen according to the state of the electronic device 1200.

[0150] The electronic device 1200 which is in each of the first state 1201, the third state 1202 and the second state 1203 may display user interfaces (i.e., first icon 1251, first information 1252, and second information 1253) related to the background screen setting on the display 1210. The electronic device 1200 which is in each of the first state 1201 and the third state 1202 may display a first icon 1251 and first information 1252 for setting the background screen on the display 1210. For example, the first information 1252 may include “Set a background screen in consideration of a to-be-slidably-retracted range”. The electronic device 1200 which is in the second state 1203 may display the first icon 1251 and second information 1253 for setting the background screen on the display 1210. For example, the second information 1253 may include “Set a background screen in consideration of a to-be-extracted range of a slide”. The user interfaces 1251, 1252, and 1253 shown in FIG. 12 are only examples. The disclosure is not limited to the illustrated examples.

[0151] Hereinafter, with reference to FIG. 13, an electronic device according to one embodiment will be described.

[0152] FIG. 13 is a view showing a preview image according to a state of the electronic device according to an embodiment of the disclosure.

[0153] Referring to FIG. 13, a state of the electronic device 1300 according to an embodiment may include a second state 1301 (e.g., an extended state) in which a display 1310 has extended, a first state 1303 (e.g., a retracted state) in which the display 1310 has retracted and a third state 1302 (e.g., an intermediate state) in which a portion of the display 1310 has retracted or extended. As the state of the electronic device 1300 is gradually changed to the second state 1301, the third state 1302, and the first state 1303, the display area of the display 1310 may be gradually reduced. The electronic device 1300 according to one embodiment may reduce and display preview images 1320, 1330 and 1340 in proportional to the reduction of the display area of the display 1310 as the state of the device is changed from the second state 1301 to the first state 1303.

The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.

[0210] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to various embodiments, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.

[0211] While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
