Display device

[0001] This application is the National Stage filing under 35 U.S.C. 371 of International Application No. PCT/KR2021/008840, filed on Jul. 9, 2021, the contents of which is hereby incorporated by reference herein in its entirety.

[0002] The present disclosure relates to a display device.

[0003] As information society develops, the demand for display devices is also increasing in various forms. In response to this, various display devices such as Liquid Crystal Display Device (LCD), Organic Light Emitting Diode (OLED), and Micro LED have been researched and used in recent years.

[0004] Among these, a liquid crystal panel includes a TFT substrate and a color filter substrate that face each other with a liquid crystal layer interposed therebetween, and may display an image by using light provided from a backlight unit. In addition, an OLED panel may display an image by depositing an organic material layer capable of self-emitting light on a substrate on which a transparent electrode is formed. In particular, a display device equipped with OLED panel has an advantage of being implemented in an ultra-thin type as it does not require a backlight unit.

[0005] A control box may be used to be spaced from the display device, and adjacent to a user. The control box may provide various information to the display device. For example, the control box may be an AV box. The control box may exchange information in a wired/wireless manner with a display head equipped with a display panel that displays images.

[0006] Recently, much research has been achieved on the connectivity of such a display device.

Meanwhile, the first antenna unit 130 may be referred to as a left antenna unit, and the second antenna unit 140 may be referred to as a right antenna unit.

[0064] For example, a patch antenna may be provided on the front surface of each of the first antenna unit 130 and the second antenna unit 140. For example, an array antenna using a dipole antenna or a monopole antenna may be provided on the left and lower side surfaces of the first antenna unit 130. For example, an array antenna using a dipole antenna or a monopole antenna may be provided on the right and lower side surfaces of the second antenna unit 140. The array antenna may have an end-fire shape.

[0065] For example, the first antenna unit 130 and the second antenna unit 140 may have a different polarization characteristic.

[0067] Referring to FIGS. 10 and 11, a plate fixing portion 57a, 57b may protrude rearward from the base 55, and may be located above the front housing 110. A first plate fixing portion 57a and a second plate fixing portion 57b may be spaced apart from each other in the left-right direction. For example, the plate fixing portion 57a, 57b may be a pemnut.

[0068] The plate 170 may be detachably coupled to the base 55 and the front housing 110 at the rear of the base 55 and the front housing 110. The plate 170 may cover a portion of the rear of the base 55 and a portion of the rear of the front housing 110. The plate fixing portion 57a, 57b may penetrate the plate 170. The plate 170 may include a material having an excellent thermal conductivity, and may be referred to as a heat sink. The plate 170 may have an overall square bracket shape, and may include a first plate 171, a second plate 172, and a third plate 173.

[0069] The first plate 171 may be located at a rear of the first antenna unit 130, and may extend long in the up-down direction. For example, the first plate 171 may be bent at least once, and an imaginary horizontal plane (i.e., an XY plane) on which an upper portion of the first plate 171 is located may be located at a rear of an imaginary horizontal plane (i.e., an XY plane) on which a lower portion of the first plate 171 is located. The rear surface of the first pad 131 may contact the lower portion of the first plate 171. That is, heat generated by the first antenna unit 130 may be transmitted to the lower portion of the first plate 171 through the first pad 131, and the heat may be transmitted from the lower portion of the first plate 171 to the upper portion of the first plate 171. Accordingly, heat of the first antenna unit 130 may be effectively removed.

[0070] The second plate 172 may be located at a rear of the second antenna unit 140, and may extend long in the up-down direction. For example, the second plate 172 may be bent at least once, the upper portion of the second plate 172 may be located on the horizontal plane where the upper portion of the first plate 171 is located, and the lower portion of the second plate 172 may be located on the horizontal plane where the lower portion of the first plate 171 is located. The rear surface of the second pad 141 may contact the lower portion of the second plate 172. That is, the heat generated by the second antenna unit 140 may be transmitted to the lower portion of the second plate 172 through the second pad 141, and may be transmitted from the lower portion of the second plate 172 to the lower portion. Accordingly, heat of the second antenna unit 140 may be effectively removed.

[0071] The third plate 173 may extend long between the upper portion of the first plate 171 and the upper portion of the second plate 172, and may be connected to the upper portion of the first plate 171 and the upper portion of the second plate 172. The third plate 173 may be located above the IR module 150. For example, the first plate 171, the second plate 172, and the third plate 173 may be formed separately, or may be coupled to each other. For another example, the first plate 171, the second plate 172, and the third plate 173 may be formed as one body.

[0072] For example, a press portion 174 may be formed by pressing the third plate 173 toward the frame 20, and may be located approximately in the center of the plate 170. A base hole 55a may be formed to penetrate the base 55 in the front-rear direction, and the press portion 174 may contact the rear surface of the frame 20 through the base hole 55a. That is, the heat of the third plate 173 may be easily transmitted to the frame 20. Accordingly, heat dissipation of the first antenna unit 130 and the second antenna unit 140 may be achieved more effectively.

[0073] Referring to FIGS. 11 and 12, a housing fixing portion 116a, 116b may protrude rearward from the inside of the front housing 110, and may be located on the partition wall 114. A first housing fixing portion 116a may be adjacent to the left side of the front housing 110, and a second housing fixing portion 116b may be adjacent to the right side of the front housing 110. For example, the housing fixing portion 116a, 116b may be a pemnut. A board pin 117a, 117b may protrude rearward from the IR module 150. A first board pin 117a may be adjacent to the left side of the IR module 150, and a second board pin 117b may be adjacent to the right side of the IR module 150.

[0074] A rear housing 120 may be detachably coupled to the base 55 and the front housing 110 at the rear of the plate 170. The rear housing 120 may form the rear surface of the communication module 100. For example, the rear surface of the communication module 100 may be located in front of the rear surface of the back cover 40 (see FIG. 17). The rear housing 120 may include a first housing 121 and a second housing 122.

[0075] The first housing 121 may be located at a rear of the first plate 171. A first opening (not denoted) may be formed to penetrate the first housing 121 in the front-rear direction, and may be located at the rear of the upper portion of the first plate 171. A first hole 120a may be formed to penetrate the first housing 121 in the front-rear direction, and may be located at the rear of the first antenna unit 130. Accordingly, the first antenna unit 130 may be cooled by air passing through the first hole 120a.

[0076] The second housing 122 may be located at a rear of the second plate 172. A second opening (not denoted) may be formed to penetrate the second housing 122 in the front-rear direction, and may be located at the rear of the upper portion of the second plate 172. A second hole 120b may be formed to penetrate the second housing 122 in the front-rear direction, and may be located at the rear of the second antenna unit 140. Accordingly, the second antenna unit 140 may be cooled by air passing through the second hole 120b.

[0077] A middle portion (no reference numeral) of the rear housing 120 may connect the first housing 121 and the second housing 122 at between the first housing 121 and the second housing 122. For example, the first housing 121, the second housing 122, and the middle portion may be formed as one body.

[0078] In addition, the first boss 56a may penetrate the first housing 121, and the second boss 56b may penetrate the second housing 122. Accordingly, the first boss 56a and the second boss 56b may guide the coupling of the rear housing 120 with respect to the base 55 and the front housing 110.

[0079] In addition, a fastening member (not shown) may penetrate the middle portion, and may be fastened to the first lower fixing portion 26a. A first fastening member Fa may penetrate the first housing 121, and may be fastened to the third lower fixing portion 56c. A second fastening member Fb may penetrate the first housing 121, and may be fastened to the first plate fixing portion 57a. A third fastening member Fc may penetrate the first housing 121, and may be fastened to the first housing fixing portion 116a. A fourth fastening member Fd may penetrate the first housing 121 and the first board pin 117a, and may be fastened to the inside of the front housing 110 (see FIG. 16).

An eighth fastening member Fg may penetrate the second housing 122 and the second board pin 117b, and may be fastened to the inside of the front housing 110.

[0080] Accordingly, the communication module 100 may be coupled to the frame 20, the pressing portion 25 (see FIG. 7), the second part 32, and the base 55, and the rigidity of the communication module 100 may be enhanced.

[0081] Meanwhile, the fastening members may be a screw. In addition, the fastening members may be spaced apart from the antenna unit 130, 140 by a certain distance or more. The fastening members may not overlap the antenna unit 130, 140 in the front-rear direction. Accordingly, beam distortion and performance degradation of the antenna unit 130, 140 caused by the fastening members may be minimized.

[0082] Meanwhile, the press portion 174 may be located between the first housing 121 and the second housing 122. The holder 190 may be fixed to the first housing 121 and the second housing 122. A cable passage HL may be formed between the holder 190 and the middle portion.

[0083] Referring to FIGS. 13 and 14, the first antenna unit 130 and the second antenna unit 140 may be spaced apart from the inside of the front housing 110 and the inside of the rear housing 120.

[0084] In the front-rear direction, the front surface of the first antenna unit 130 and the front surface of the second antenna unit 140 may be spaced apart from the front housing 110 by a first gap ga. In the front-rear direction, the rear surface of the first plate 171 and the rear surface of the second plate 172 may be spaced apart from the inside of the rear housing 120 by a second gap gb. In the up-down direction, the upper end of the first antenna unit 130 and the upper end of the second antenna unit 140 may be spaced apart from the front housing 110 by a third gap gc. In the up-down direction, the lower end of the first antenna unit 130 and the lower end of the second antenna unit 140 may be spaced apart from the front housing 110 by a fourth gap gd.

[0085] For example, the first gap ga may be 1 to 4.5 mm, and the fourth gap gd may be 1 mm or less. For example, the second gap gb may be larger than the first gap ga, and the third gap gc may be larger than the fourth gap gd. For example, the left side of the first antenna unit 130 may be spaced apart from the left side of the front housing 110 by a gap of 0.5 mm or less. For example, the right side of the second antenna unit 130 may be spaced apart from the right side of the front housing 110 by a gap of 0.5 mm or less.

[0086] For example, the thickness ta of the front end of the front housing 110, the thickness tb of the lower end, the thickness of the left end, and the thickness of the right end may be 1 to 1.5 mm. For example, the front housing 110 may include resin. For example, the front housing 110 may include polycarbonate PC.

[0087] Accordingly, beam distortion and performance degradation of the first antenna unit 130 and the second antenna unit 140 caused by the front housing 110 may be minimized.

[0088] The thickness of the rear housing 120 may be 1 to 1.5 mm. For example, the rear housing 120 may include resin. For example, rear housing 120 may include PC ABS.

[0089] Accordingly, beam distortion and performance degradation of the first antenna unit 130 and the second antenna unit 140 caused by the rear housing 120 may be minimized. In addition, the heat from the first antenna unit 130 and the second antenna unit 140 may be easily radiated to the outside through the rear housing 120.

[0090] Meanwhile, a contact portion 110u of the front housing 110 may contact the lower side of the vertical portion 32V, and may be spaced rearward from the front end of the vertical portion 32V. The front surface 110t of the front housing 110 may be inclined rearward with respect to the contact portion 110u (see theta 1). The lower surface 110d of the front housing 110 may be spaced upward from the lower end 120e of the rear housing 120.

[0091] In addition, among the antennas provided on the front surface of the first antenna unit 130, an imaginary straight line connecting the antenna TPa disposed closest to the vertical portion 32V and the front end of the vertical portion 32V may form a certain angle (theta a) with respect to an imaginary straight line parallel to the front-rear direction. As the angle (theta a) increases, the radio wave reception range of the antenna TPa may increase, but the height of the communication module 100 protruding downward from the vertical portion 32V may increase. For example, the angle (theta a) may be approximately 30 degrees. Accordingly, a sufficient radio wave reception range of the antenna TPa can be secured without significantly increasing the height of the communication module 100.

[0092] In addition, among the antennas provided on the front surface of the first antenna unit 140, an imaginary straight line connecting the antenna TPb disposed closest to the vertical portion 32V and the front end of the vertical portion 32V may form a certain angle (theta b) with respect to an imaginary straight line parallel to the front-rear direction. As the angle (theta b) increases, the radio wave reception range of the antenna TPb may increase, but the height of the communication module 100 protruding downward from the vertical portion 32V may increase. For example, the angle (theta b) may be approximately 30 degrees. Accordingly, a sufficient radio wave reception range of the antenna TPa can be secured without significantly increasing the height of the communication module 100. For example, the angle theta b may be substantially equal to the angle theta a.

[0093] Referring to FIG. 15, the cable C may transmit digital video data and timing control signals from the timing controller board 52 to the display panel 10 (see FIG. 3). A first cable Ca may electrically connect the second board 53 and the timing controller board 52. A second cable Cb may electrically connect the first board 54 and the second board 53, and may be a flexible flat cable FFC. A third cable Cc may electrically connect the first and second antenna units 130 and 140 of the communication module 100 and the first board 54. A fourth cable Cd may electrically connect the second board 53 and the first board 54, and may be a power cable. A fifth cable Ce may electrically connect the second board 53 and the first and second antenna units 130 and 140 of the communication module 100, and may be a power cable.

[0094] For example, the first board 54 may be referred to as a RF receiver 54, a RF processor 54, or a WAV board 54. In addition, the third cable Cc may be a radio frequency cable (RF cable) Cc. In this case, as the length of the third cable Cc increases, the loss rate of the data transmitted from the communication module 100 to the first board 54 may increase. For example, the length of the third cable Cc may be about 300 mm or less. In this case, the distance d11 between the lower end of the communication module 100 and the vertical portion 32V of the second part 32 and the distance d12 between the vertical portion 32V and the upper end of the first board 54 may be designed in such a way that the length of the third cable Cc can be arranged to be 300 mm. That is, the first board 54 may be disposed closer to the second part 32 than to the first part 31. In other words, the communication module 100 may be provided at the edge of the display device, the antenna unit 130, 140 may be located outside of the edge, the WAV board 54 may be located within a certain distance inside the edge, and the length of the RF cable Cc may be 300 mm or less. Accordingly, the data loss rate caused by the third cable Cc may be minimized.

[0095] Meanwhile, the first board 54 may be a relatively high temperature heat source. The first board 54 may be spaced downward from the timing controller board 52. The timing controller board 52 may be disposed closer to the first part 31 than to the second part 32. For example, the distance d21 between the upper end of the first board 54 and the lower end of the timing controller board 52 is greater than the distance d12 between the vertical portion 32V and the upper end of the first board 54. Accordingly, damage or performance degradation of the timing controller board 52 due to heat of the first board 54 may be minimized.

[0096] For example, the second board 53 may be an AMP board 53 or a main board 53. The heating value of the second board 53 may be less than that of the first board 54. In this case, the second board 53 may be spaced left or right from the timing controller board 52. For example, the distance d13 between the left distal end of the second board 53 and the right distal end of the timing controller board 52 may be smaller than the distance d21 between the upper end of the first board 54 and the lower end of the timing controller board 52. Accordingly, in comparison with a case where the AMP board 53 is integrated with or located adjacent to the WAV board 54, heat transmitted to the timing controller board 52 may be reduced.

[0097] A heat sink 540 may be coupled to the rear surface of the first board 54. The heat sink 540 may include a material having an excellent thermal conductivity, such as metal. For example, the heat sink 540 may extend left and/or right from the first board 54. For another example, the heat sink 540 may extend upward from the first board 54. In this case, the timing controller board 52, the heat sink 540, the first board 54, and the communication module 100 may be located on the center line V-V′ of the display device. Further, the vertical line VI-VI′ passing through the center of the second board 53 may be eccentric to a certain distance e to the right with respect to the center line V-V′. In addition, the upper end of the heat sink 540 may be spaced downward by a certain distance d22 from the lower end of the timing controller board 52.

[0098] Accordingly, the heat of the first board 54 may be transmitted to the heat sink 540, and damage or performance degradation of the timing controller board 52 due to the heat of the first board 54 and/or the heat sink 540 may be minimized.

[0099] Meanwhile, a buffer member 541 may be coupled or attached to the rear surface of the heat sink 540. The buffer member 541 may be disposed between the heat sink 540 and the back cover 40 (see FIG. 3), and may relieve external force applied to the back cover 40. For example, the buffer member 541 may be a sponge.

[0109] In addition, according to another aspect of the present disclosure, the display device may further include: a back cover covering a rear of the frame; and a buffer member positioned between the heat sink and the back cover, and coupled to a rear surface of the heat sink.
