[0063] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. Hereinafter, expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

[0064] Hereinafter, a plurality of displays 110 according to a first exemplary embodiment will be described with reference to the attached drawings.

[0065] As shown in FIGS. 1 and 2, a multivision display system 10 according to the first exemplary embodiment includes the plurality of displays 110 and a stand 120 that allows or supports the plurality of displays 110 to stand on a horizontal surface.

[0066] Each of the plurality of displays 110 includes a display module 111 (e.g., display panel) on which images are displayed and a case 112 that contains the display module 111.

[0067] The stand 120 includes a base 121 supported by the horizontal surface, as shown in FIGS. 2 and 3, a plurality of coupling frames 122 fixed to a rear surface of the display 110 and mutually coupled to each other in a vertical direction, and a dummy module 123 installed between the base 121 and the display 110 to allow the display 110 to be installed at a certain height.

[0068] The base 121 is formed in an approximate hexagonal shape, which the dummy module 123 is installed on. Casters may be rotatably installed below the base 121 for moving the multivision display system.

[0069] The coupling frames 122 each have a bar shape that extends up and down to be long. Two coupling frames 122 are installed on both sides of the rear surface of the display 110 to individually control the heights of both sides of the display 110. Accordingly, the heights of both sides of the display 110 are controlled using the two coupling frames 122, thereby adjusting a level of the display 110. In the present exemplary embodiment, the coupling frames 122 are installed on both sides of the rear surface of the display 110. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, the coupling frames 122 may be installed on both sides of the display 110.

[0070] The coupling frames 122, as shown in FIG. 4, each include a coupling portion 122a that protrudes from a bottom end of the coupling frame 122 and is coupled with the coupling frame 122 located adjacent to the bottom end, and a coupling groove 122b provided on a top end of the coupling frame 122 and into which the coupling portion 122a of the coupling frame 122 located adjacent to a top thereof is inserted. In the present exemplary embodiment, the coupling portion 122a protrudes from the bottom end of the coupling frame 122 and the coupling groove 122b is provided on the top end of the coupling frame 122. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, a coupling portion 122a may extend from a top end of a coupling frame 122 and a coupling groove 122b may be provided on a bottom end of the coupling frame 122.

[0071] The dummy module 123, as shown in FIG. 2, allows the plurality of displays 110 to be installed (e.g., provided) while being separate from the horizontal surface by a certain distance, thereby providing a screen of the multivision display system 10 at the certain distance. The coupling frames 122 are installed on both sides of a rear surface of the dummy module 123, respectively. The dummy module 123 may include various substrates which control an operation of the multivision display system 10.

[0072] The plurality of displays 110, as shown in FIG. 5, are installed vertically on the stand 120 using the coupling frames 122 and a plurality of stands 120 on which the plurality of displays 110 are installed, respectively, are disposed horizontally adjacent to each other, thereby disposing the plurality of displays 110 vertically and horizontally adjacent to each other.

[0073] In the present exemplary embodiment, four displays 110 are installed on each of two stands 120 that are disposed horizontally adjacent to each other, thereby forming the multivision display system 10 using a total of eight displays 110.

[0074] As described above, the plurality of displays 110 installed with the coupling frames 122 on the rear surface may be sequentially stacked on one of the base 121 and the dummy module 123, thereby easily constructing the multivision display system 10 in which the plurality of displays 110 are disposed vertically. Also, the plurality of stands 120 on which the plurality of displays 110 are disposed vertically are disposed left and right, thereby easily constructing the multivision display system 10 in which the plurality of displays 110 are disposed left and right.

[0075] In the multivision display system 10 described above, the displays 110 disposed vertically and horizontally may be slightly misaligned from one another due to a tolerance, which causes a phenomenon in which locations of parts of images are misaligned on the entire screen. Thus, it is desirable to reduce a level difference between adjacent displays 110.

[0076] Accordingly, the multivision display system 10, as shown in FIG. 6, includes a position adjuster for adjusting the level difference between the adjacent displays 110 which are disposed vertically or horizontally adjacent to each other.

[0077] The position adjuster may adjust the level difference between the displays 110 disposed adjacent to each other by adjusting a position of the coupling portion 122a of the adjacent coupling frame 122 coupled with the coupling groove 122b.

[0078] To align horizontal positions of the two displays 110 disposed vertically, the coupling groove 122b is formed (e.g., provided) to have a relatively greater width than the coupling portion 122a in such a way that the coupling portion 122a of the adjacent coupling frame 122 coupled with the coupling groove 122b is movable left and right in the coupling groove 122b.

[0079] The position adjuster includes a left and right adjusting screw 124 (e.g., horizontal adjusting screw) that is coupled with a top of the coupling frame 122 in such a way that a front end thereof protrudes into the coupling groove 122b and supports the coupling portion 122a coupled with the coupling groove 122b to move the coupling portion 122a left and right.

[0080] Accordingly, as shown in FIGS. 7 and 8, the left and right adjusting screw 124 is rotated forward and backward in such a way that the coupling portion 122a moves left and right due to the left and right adjusting screw 124. Accordingly, the display 110 located above the left and right adjusting screw 124 moves left and right, thereby aligning left and right positions of the two displays 110 disposed vertically.

[0081] Also, to align top and bottom positions of the two adjacent displays 110 disposed left and right, the position adjuster includes an elevating guide 125 disposed inside the coupling groove 122b to allow the coupling portion 122a to move vertically, thereby moving the displays 110.

[0082] The elevating guide 125 is installed inside the coupling groove 122b to be movable left and right, and a top surface thereof is formed to be inclined. Also, the coupling portion 122a is formed to allow a bottom surface thereof to be inclined to correspond to the top surface of the elevating guide 125.

[0083] The position adjuster includes a top and bottom adjusting screw 126 that is coupled with the top of the coupling frame 122 in such a way that a front end thereof protrudes into the coupling groove 122b and moves the elevating guide 125 disposed inside the coupling groove 122b.

[0084] Accordingly, as shown in FIGS. 9 and 10, the elevating guide 125 is moved left and right by rotating the top and bottom adjusting screw 126 forward and backward in such a way that the coupling portion 122a of the coupling frame 122 moves up and down as the elevating guide 125 moves, thereby moving the display 110 installed with the coupling frame 122 up and down. Herein, since the coupling frames 122 are installed on both sides of the rear of the display 110, respectively, the heights of the both sides of the display 110 may be adjusted, respectively.

[0085] In the configuration described above, rollers 125a and 122c are rotatably installed on a bottom of the elevating guide 125 and a bottom of the coupling portion 122a, respectively, in such a way that the movement of the elevating guide 125 and the movement of the coupling frame 122 are performed smoothly.

[0086] Also, as shown in FIG. 11, to align front and rear positions of the two adjacent displays 110 disposed horizontally to each other, a clamp 127 is installed on the coupling frame 122.

[0087] The clamp 127 is installed on each of the two coupling frames 122 installed adjacent to each other, on the rear surfaces of the adjacent displays 110. The clamps 127 are formed in an L shape, are fixed to the two adjacent coupling frames 122, respectively, and are mutually fixed using coupling members S such as screws.

[0088] Accordingly, front and rear positions of the two clamps 127 coupled with each other are adjusted to adjust mutual positions of the two adjacent displays 110 and then the two clamps 127 are fixed using the members S, thereby allowing the front and rear positions of the two displays 110 to be aligned.

[0089] Also, one fixing plate 128 is fixed to tops of the two coupling frames 122 located uppermost among the coupling frames 122 using the coupling members S to mutually fix the tops of the two coupling frames 122.

[0090] In the multivision display system 10, as shown in FIGS. 12 and 13, spacers 129 are disposed to prevent gaps that may occur inevitably due to tolerances among four side surfaces, provided vertically and horizontally, of the two displays 110 mutually adjacent to each other.

[0091] The spacers 129 are formed to have an approximate rectangular cross section while extending to correspond to the side surfaces of the display 110. Also, the spacers 129 are formed of an elastic-deformable material and the four side surfaces, provided vertically and horizontally on the case 112, of the display 110 are concave and provide accommodating grooves 112a that contain a part of the spacer 129, respectively.

[0092] In the present exemplary embodiment, the accommodating grooves 112a are provided in central portions of the four top, bottom, left, and right surfaces of the display 110 and the spacers 129 are formed to have a relatively greater thickness than a depth of the accommodating groove 112a. Accordingly, when the spacer 129 is installed in the accommodating groove 112a of the display 110, one part of the spacer 129 is accommodated in the accommodating groove 112a and the other part of the spacer 129 protrudes from the outside of the accommodating groove 112a to be accommodated in the accommodating groove 112a provided in the adjacent display 110. Accordingly, as shown in FIGS. 14 and 15, even though a gap is caused by at least one of a tolerance between side surfaces of the displays in contact with each other and an uneven surface, the gap is blocked by the spacer 129. Also, even though a light source exists in the rear of the multivision display system 10, light generated by the light source is prevented from passing through the gap between the side surfaces of the displays 110 and being transferred forward.

[0093] In the present exemplary embodiment, the accommodating groove 112a is provided in the central portions of the side surfaces of the displays 110. However, it is understood that one or more other exemplary embodiments are not limited thereto. As shown in FIGS. 16 and 17, according to a second exemplary embodiment, an accommodating groove 112a′ may be formed with a step on a rear end of the side surface of the display 110.

[0094] Also, in the second exemplary embodiment, a spacer 129′ is formed to have an approximate rectangular cross section, in which a concavo-convex shape is formed on one side of the spacer 129′ to allow the spacer 129′ to be more easily elastic-deformable while the displays 110 are being installed on the stand 120.

[0095] Also, as shown in FIG. 18, according to a third exemplary embodiment, a spacer 129″ is formed to have a T-shaped cross section in such a way that portions extending vertically may be supported by the rear surfaces of the two displays 110 and a horizontally protruding portion may be inserted between the side surfaces of the displays 110. Herein, the horizontally protruding portion of the spacer 129″ may be inserted between the side surfaces of the two displays 110 or may be attached to the side surface of the display 110. In this case, it is unnecessary to form accommodating grooves in the displays 110 as in the previously-described exemplary embodiments.

[0096] In the third exemplary embodiment, the stands 120 each include (or are connected to) one dummy module 123, though it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, each of the stands 120 may include (or be connected to) a plurality of dummy modules 123. According to another exemplary embodiment, the stand 120 may not have a configuration corresponding to the dummy module 123 and the coupling frames 122 may be directly installed on the base 121.

[0097] Also, in the present exemplary embodiment, the multivision display system 10 is formed with the two stands 120 on each of which the four displays 110 are installed, respectively. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to a preferable width and height of the multivision display system 10, various numbers of displays 110 and stands 120 may be used to form the multivision display system 10.

[0098] In the present exemplary embodiment, the two coupling frames 122 are coupled with both sides of the rear surface of the display 110, respectively. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, the coupling frames 122 may be installed on both side surfaces of the display 110.

[0099] Also, in the present exemplary embodiment, the two coupling frames 122 are installed on the display 110 to adjust the level of the display 110. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, only one coupling frame 122 may be installed with each display 110 while the display 110 is rotatably coupled with the coupling frame 122 to adjust the level of the displays 110 by rotating the display 110. Also, top and bottom positions of the displays 110 are adjusted using the coupling frames, thereby mutually aligning heights of the displays disposed horizontally.

[0100] In the present exemplary embodiment, the coupling frame 122 is separately provided from the display 110 and installed on the display 110. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, a coupling portion 122a and a coupling groove 122b may be formed in a case forming an exterior of a display 110 and a position adjuster may be installed therein.

[0101] Also, in the present exemplary embodiment, the coupling frame 122 is coupled with the rear surface of the display 110, that is, the outer side thereof. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, the coupling frame 122 may be coupled while being accommodated in a case forming an exterior of the display 110.

[0102] Also, in the present exemplary embodiment, the coupling frame 122 is formed to have a bar shape extending up and down. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, the coupling frame 122 may be formed to have a bar extending horizontally or may be formed to have various shapes other than the bar shape depending on a design.

[0103] Hereinafter, a multivision display system 20 according to the third exemplary embodiment will be described in detail with reference to the drawings.

[0104] As shown in FIGS. 19 and 20, the multivision display system 20 includes a plurality of displays 210 disposed vertically and horizontally to each other and a plurality of wall mounts 220 that are fixed to the wall vertically and horizontally to each other and support the displays 210, respectively. In the present exemplary embodiment, the multivision display system 20 includes a total of six displays 210 that are disposed vertically in three rows and horizontally in two columns and includes a total of six wall mounts 220 installed on the wall vertically in three rows and horizontally in two columns to correspond to the displays 210.

[0105] The wall mounts 220, as shown in FIG. 21, include a fixed bracket 221 fixed to the wall, a mobile bracket 222 installed to be movable forward and backward with respect to the fixed bracket 221, and a link assembly 223 that allows the mobile bracket 222 to be movably installed on the fixed bracket 221. The display 210 is installed on the mobile bracket 222. Accordingly, the display 210 is installed on the wall using the wall mount 220 to be movable forward and backward.

[0106] In the multivision display system 20, to mutually align horizontal positions of the displays 210 disposed vertically, the display 210 is installed on the wall mount 220 to be movable horizontally.

[0107] For this, as shown in FIGS. 21 and 22, a guide rail 222a which extends long left and right is provided on the mobile bracket 222 of the wall mount 220. An engaging member 211 is installed on the rear surface of the display 210 to allow the display 210 to be attached and installed in the guide rail 222a. Two engaging members 211 are installed on both sides of the rear surface of the display 210, and each of the engaging members 211 includes an engaging portion 211a that fits in a top end of the guide rail 222a.

[0108] In the present exemplary embodiment, the two guide rails 222a are disposed in a top and bottom of the mobile bracket 222 with a gap. The engaging portions 211a that fit on the two guide rails 222a respectively are provided at a top and bottom of each of the engaging members 211.

[0109] Accordingly, the engaging member 211 may move horizontally along the guide rail 222a while fitting on the guide rail 222a using the engaging portion 211a. Thus, a user may move the displays 210 by applying a force to the left and right of the displays 210 to align the left and right positions of the displays 210 disposed vertically.

[0110] The engaging portion 211a includes an elevating screw 212 that is rotatably installed on the engaging portions 211a and includes a bottom end passing through the engaging portion 211a and supported by the guide rail 222a. A cap 212a formed of rubber covers the bottom end of the elevating screw 212, and the bottom end of the elevating screw 212 is allowed to be supported by the guide rail 222a via the cap 212a.

[0111] Accordingly, as the elevating screw 212 is rotated, the elevating screw 212 moves vertically, thereby moving the display 210 vertically. Therefore, the user may align top and bottom positions of the displays 210 disposed horizontally adjacent to each other while rotating the elevating screw 212.

[0112] Also, the guide rail 222a is installed on the mobile bracket 222 to be movable forward and backward to adjust a position of the display 210 forward and backward. To allow the guide rail 222a to move forward and backward, as shown in FIGS. 23 and 24, a forward and backward adjusting screw 222b is installed on each of both sides of the guide rail 222a and a forward and backward adjusting nut 222c rotatably installed in the mobile bracket 222 and screw-coupled with the forward and backward adjusting screw 222b is disposed in the mobile bracket 222.

[0113] Accordingly, when rotating the forward and backward adjusting nut 222c coupled with the forward and backward adjusting screw 222b, as shown in FIG. 25, the forward and backward adjusting screw 222b moves forward and backward and the guide rail 222a moves forward and backward together with the forward and backward adjusting screw 222b. Since the display 210 is installed while being attached in the guide rail 222a using the engaging member 211, the display 210 moves forward and backward together with the guide rail 222a.

[0114] Therefore, the user may mutually align front and rear positions of the displays 210 disposed vertically to each other by rotating the forward and backward adjusting nut 222c forward and backward.

[0115] The link assembly 223, as shown in FIG. 21, includes a first link 223a with one end rotatably installed on the fixed bracket 221 and another end installed on the mobile bracket 222 to be rotatable and movable vertically, and a second link 223b with one end rotatably installed on the mobile bracket 222 and another end installed on the fixed bracket 221 to be rotatable and movable vertically. The first link 223a and the second link 223b are installed to allow central portions thereof to be rotatable.

[0116] Accordingly, since the displays 210 move horizontally using the guide rail 222a, move vertically using the elevating screw 212, and move forward and backward using the forward and backward adjusting screw 222b and the forward and backward adjusting nut 222c, relative positions of the displays 210 may be adjusted to be precisely aligned.

[0117] Also, the wall mount 220, as shown in FIG. 26, includes a locking device 224 for restricting the movement of the mobile bracket 222. In the present exemplary embodiment, the locking device 224 includes a locking member 224a installed in guide slots 221a provided on the fixed bracket 221 to be movable vertically, an elastic member 224b that elastically supports the locking member 224a upward, and a locking portion 222d that is provided on the mobile bracket 222 and fits on the locking member 224a to lock the locking member 224a. In the present exemplary embodiment, locking devices 224 are provided on upper portions and lower portions of both sides of the wall mount 220, respectively.

[0118] In the present exemplary embodiment, to easily install the display 210, the wall mount 220 includes the fixed bracket 221, the mobile bracket 222, and the link assembly 223 to move the display 210 forward and backward. However, it is understood that one or more other exemplary embodiments are not limited thereto. For example, according to another exemplary embodiment, the wall mount 220 may include only the fixed bracket 221, and the guide rail 222a may be installed on the fixed bracket 221.

[0119] As described above, displays may be installed vertically adjacent by coupling frames installed on rear surfaces of displays with one another and may be disposed horizontally adjacent by disposing stands horizontally, on which the displays are installed, thereby easily installing a multivision display system.

[0120] Also, since displays may be moved vertically, horizontally, and forward and backward, top, bottom, left, right, front, and rear positions of the displays may be easily aligned with one another.

[0121] Although a few exemplary embodiments have been shown and described above, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
