[0070] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0071] FIG. 1 is a front perspective view of a display device according to one embodiment.

[0072] Referring to FIG. 1, a display device (1) is a device that processes an image signal received from the outside and can visually display the processed image. In the following, the display device (1) is exemplified as a television (TV), but is not limited thereto. For example, the display device (1) can be implemented in various forms such as a monitor, a portable multimedia device, a portable communication device, etc., and the form of the display device (1) is not limited as long as it is a device that visually displays an image.

[0073] In addition, the display device (1) may be a large format display (LFD) installed outdoors, such as on a building rooftop or a bus stop. Here, the outdoors is not necessarily limited to outdoors, and the display device (1) according to one embodiment may be installed in any indoor location where a large number of people may enter and exit, such as a subway station, shopping mall, movie theater, company, or store.

[0074] The display device (1) can receive content including video signals and audio signals from various content sources, and output video and audio corresponding to the video signals and audio signals. For example, the display device (1) can receive content data via a broadcast reception antenna or a wired cable, receive content data from a content playback device, or receive content data from a content provider's content provision server.

[0075] FIG. 2 is a rear perspective view of a display device according to one embodiment.

[0076] Referring to FIG. 2, the rear exterior of the display device (1) can be formed by a rear chassis (40) and a rear cover (50).

[0077] The rear cover (50) may be coupled to the rear of the rear chassis (40). The rear cover (50) may be coupled to the rear of the rear chassis (40) and to the lower center thereof. The rear cover (50) may be provided to cover a portion of the rear chassis (40). The remaining portion of the rear chassis (40) that is not covered by the rear cover (50) may have a thinner thickness than the portion. According to one embodiment, the thickest portion of the display device (1) may be the portion where the rear cover (50) is provided. The larger the area of ​​the rear cover (50), the larger the area of ​​the thick portion of the display device (1). Therefore, as the area of ​​the rear cover (50) is reduced, the user may feel that the overall thickness of the display device (1) is thinner. According to the spirit of the present invention, by minimizing the area of ​​the rear cover (50), an ultra-slim appearance of the display device (1) can be realized.

[0078] More specifically, one end of the rear cover (50) and one end of the rear chassis (40) may be spaced apart from each other by a predetermined distance. Similarly, the other end of the rear cover (50) and the other end of the rear chassis (40) may be spaced apart from each other by the predetermined distance. In other words, the left end of the rear cover (50) and the left end of the rear chassis (40) may be spaced apart from each other by a first distance, and the right end of the rear cover (50) and the right end of the rear chassis (40) may be spaced apart from each other by the first distance. By the above structure, the peripheral portions on both sides of the display device (1) and the peripheral portions on the top surface of the display device (1) may be very thin. However, it is not limited thereto, and the left end of the rear cover (50) and the left end of the rear chassis (40) may be spaced apart by a first distance, and the right end of the rear cover (50) and the right end of the rear chassis (40) may be spaced apart by a second distance that is different from the first distance.

[0079] Fig. 3 is a front exploded perspective view of a display device according to one embodiment. Fig. 4 is a rear exploded perspective view of a display device according to one embodiment.

The heat dissipation sheet (20) may increase the contact area with the self-luminous panel (11) to effectively absorb heat from the self-luminous panel (11). To this end, the heat dissipation sheet (20) and the self-luminous panel (11) may be joined by an adhesive member.

[0087] The heat dissipation sheet (20) may be composed of at least one of graphite, aluminum, and copper. Preferably, the heat dissipation sheet (20) may be composed of graphite.

[0088] According to one embodiment, the heat dissipation sheet (20) may be provided to be detachable from the rear chassis (40). In other words, the heat dissipation sheet (20) may not be coupled to the rear chassis (40). Therefore, the heat dissipation sheet (20) may be detachable from the rear chassis (40) without any restrictions.

[0089] The front chassis (30) may be provided to cover the side of the display panel (10). The front chassis (30) may be formed to extend along the perimeter of the display panel (10). Accordingly, the front chassis (30) may be provided in an approximately square ring shape.

[0090] The rear chassis (40) may be provided in a size corresponding to the display panel (10). The rear chassis (40) may be provided to cover the rear surface of the display panel (10). As described above, the rear chassis (40) may form the rear exterior of the display device (1) together with the rear cover (50).

[0091] The inner plate (60) is provided in a size corresponding to that of the rear chassis (40) and can be coupled to the front of the rear chassis (40). The inner plate (60) can be coupled to the rear chassis (40) to reinforce the rigidity of the rear chassis (40) and to dissipate heat generated from the display panel (10).

[0092] The rear cover (50) may be provided to cover a portion of the rear of the rear chassis (40). The rear cover (50) may be coupled to the rear of the rear chassis (40) to form an internal space. In the internal space formed between the rear cover (50) and the rear chassis (40), a T-con board (timing controller, not shown), a main board (not shown), a power supply unit (not shown), etc. may be provided.

[0093] Fig. 5 is a rear view of a display device according to one embodiment, with the rear cover removed. Fig. 6 is an enlarged view of A in Fig. 5 from a different angle. Fig. 7 is a view showing the wires separated from Fig. 6.

[0094] Referring to FIGS. 5 to 7, a display device (1) according to one embodiment allows a user to easily pull out a wire (130) without a separate member. The wire (130) is a component that connects a panel holder (100) and a support frame (110) to be described later, and by pulling out the wire (130), the connection between the panel holder (100) and the support frame (110) can be released.

[0095] More specifically, when the rear cover (50) is removed from the display device (1), the chassis hole (41) may be exposed to the outside. The rear chassis (40) may include a chassis hole (41) through which a wire (130) passes. The chassis hole (41) may be covered by the rear cover (50). The chassis hole (41) may be provided within an area of ​​the rear chassis (40) covered by the rear cover (50). The wire (130) may be provided to be accessible from the rear of the rear chassis (40). At least a portion of the wire (130) may be exposed to the outside through the chassis hole (41) of the rear chassis (40). A user may detach the wire (130) from the display device (1) to release the connection between the display panel (10) and the rear chassis (40). The wire (130) can be extended to the rear of the rear chassis (40) through the chassis hole (41).

[0096] Referring to FIGS. 6 and 7, the wire (130) can be pulled out of the display device (1) by moving laterally. The wire (130) can be pulled out of the rear chassis (40) by passing through the chassis hole (41).

[0097] The bent end (131) of the wire (130) can be inserted into the wire hole (108) of the panel holder (100). After the bent end (131) of the wire (130) is pulled out from the wire hole (108), the wire (130) can be pulled out to the outside of the display device (1) by pulling the wire (130) laterally. When the wire (130) is pulled out to the outside of the display device (1), the connection between the panel holder (100) and the support frame (110) can be released.

[0098] A panel holder (100) and a support frame (110) connected by a wire (130) may be provided on each of the rear sides of the display panel (10). A bottom frame (70) may be provided between the pair of panel holders (100) and the pair of support frames (110). The bottom frame (70) may be provided at the center bottom of the rear chassis (40). A fastening hole (71) through which a fastening member such as a screw passes may be provided in the bottom frame (70). Since the fastening hole (71) of the bottom frame (70) is covered by the rear cover (50), the lower end of the display panel (10) and the lower end of the rear chassis (40) may be connected using a fastening member such as a screw as in the related art.

[0099] On the other hand, for the two sides of the rear chassis (40) that are not covered by the rear cover (50), the rear chassis (40) forms the rear exterior of the display device (1). For a neat appearance, it is preferable that the rear chassis (40) exposed to the outside not have fastening holes or the like.

[0100] According to the idea of ​​the present invention, it is possible to provide a structure in which both side ends of a rear chassis (40) and the corresponding both side ends of a display panel (10) can be detachably coupled without including a fastening hole. More specifically, by coupling and decoupling a panel holder (100) coupled to the rear of the display panel (10) and a support frame (110) coupled to the front of the rear chassis (40), the display panel (10) can be coupled to or separated from the rear chassis (40).

[0103] The panel holder (100) may be provided adjacent to the bottom of the display panel (10). In addition, the panel holders (100) may be provided in pairs, respectively provided on one side and the other side of the display panel (10).

[0104] The support frame (110) can be coupled to the front of the rear chassis (40) so as to correspond to the panel holder (100). The support frame (110) can be positioned adjacent to the lower end of the rear chassis (40). In addition, the support frames (110) can be provided in pairs, respectively, on one side and the other side of the rear chassis (40).

[0105] Referring to FIGS. 9 and 10, a wire (130) can be coupled to the panel holder (100). The wire (130) can be coupled to the panel holder (100) by passing laterally across the panel holder (100). The wire (130) can be coupled to the panel holder (100) by passing through the second hole (104) of the panel holder (100) and being received in the wire receiving groove (103). The bent end (131) of the wire (130) can be inserted into the wire hole (108) of the panel holder (100) so that the position of the wire (130) is fixed. By inserting the bent end (131) of the wire (130) into the wire hole (108), the wire (130) can be maintained in a state of being coupled to the panel holder (100).

[0106] According to one embodiment, the panel holder (100) may include a plate-shaped holder body (101), a first hole (102), a second hole (104), and a third hole (105) formed through the holder body (101). In addition, the panel holder (100) may include a wire receiving groove (103) provided to receive a wire (130), and a protrusion support portion (106) provided to contact a second protrusion (113) of a support frame (110). In addition, the panel holder (100) may include a wire hole (108) provided to insert a bent end of the wire (130).

[0107] Referring to FIG. 9, the support frame (110) may include a plate-shaped frame body (111), a first protrusion (112) protruding from the frame body (111) toward the panel holder (100), and a second protrusion (113) spaced apart from the first protrusion (112).

[0108] The first protrusion (112) can be inserted into the first hole (102) of the panel holder (100) and can be provided to come into contact with the first portion of the wire (130) and support the first portion. The second protrusion (113) can be inserted into the third hole (105) of the panel holder (100) and can be provided to engage with the protrusion support portion (106) of the panel holder (100). By engaging the second protrusion (113) and the protrusion support portion (106), the panel holder (100) can be prevented from being separated forward from the support frame (110).

[0109] Referring to FIGS. 11 and 12, the panel holder (100) and the support frame (110) may be coupled by a wire (130). As described above, when the second protrusion (113) and the protrusion support portion (106) are engaged with each other, the panel holder (100) may be restricted from moving forward of the support frame (110). However, when the panel holder (100) is moved upward a predetermined distance with respect to the support frame (110), the panel holder (100) may be separated forward from the support frame (110). To prevent this, a wire (130) may be coupled to the panel holder (100) and the support frame (110). In other words, the wire (130) may be positioned between the panel holder (100) and the support frame (110).

[0110] When the wire (130) is coupled to the panel holder (100) and the support frame (110), the panel holder (100) can be restricted from moving upward with respect to the support frame (110). In addition, the first part of the wire (130) is supported by the panel holder (100), and the second part of the wire (130) that is different from the first part is supported by the support frame (110), so that the panel holder (100) and the support frame (110) can be fixed so as not to move in the front-back direction.

[0111] More specifically, a first portion of the wire (130) may be supported by a first protrusion (112) of a support frame (110), and a second portion of the wire (130) may be received in a wire receiving groove (103). The second portion of the wire (130) may be supported by one surface of a panel holder (100) forming the wire receiving groove (103). The second portion of the wire (130) may refer to a pair of points provided on both sides of the first portion of the wire (130). The first protrusion (112) supporting the first portion of the wire (130) and the wire receiving groove (103) supporting the second portion of the wire (130) may be spaced apart from each other in the front-back direction. The first part of the wire (130) supported by the first protrusion (112) and the second part of the wire (130) supported by the wire receiving groove (103) are spaced apart in the front-back direction so that the wire (130) can be bent. As the wire (130) is bent, the panel holder (100) and the support frame (110) can be joined without a gap in the front-back direction by the tension of the wire (130).

[0112] Fig. 13 is a cross-sectional view taken along BB of Fig. 11, showing the display panel and the rear chassis together.

[0113] Referring to FIG. 13, as described above, the panel holder (100) and the support frame (110) can be combined without a gap in the front-back direction. Since the panel holder (100) is combined with the display panel (10) and the support frame (110) is combined with the rear chassis (40), the display panel (10) can be combined with the rear chassis (40) by the combination of the panel holder (100) and the support frame (110).

[0114] Figure 14 is a drawing showing a panel holder and a wire connected to the panel holder before being connected to a support frame. Figure 15 is a drawing showing a process of connecting a panel holder and a wire connected to the panel holder to a support frame. Figure 16 is a drawing showing a panel holder and a wire connected to the panel holder after being connected to a support frame.

[0115] The process of attaching the panel holder (100) to the support frame (110) is described with reference to FIGS. 14 to 16.

[0116] Referring to FIGS. 14 to 16, when the panel holder (100) is coupled to the support frame (110), the display panel (10) may not be coupled to the panel holder (100). According to one embodiment, after the panel holder (100) is coupled to the support frame (110), the display panel (10) may be coupled to the panel holder (100).

[0117] When connecting the panel holder (100) to the support frame (110), the wire (130) may be connected to the panel holder (100) first. With the wire (130) connected to the panel holder (100), the panel holder (100) may be connected to the support frame (110).

[0118] Referring to FIG. 14, the panel holder (100) can be moved so that the first portion of the wire (130) is positioned below the first protrusion (112). By moving the panel holder (100) obliquely with respect to the support frame (110), the first portion of the wire (130) can be positioned below the first protrusion (112).

[0119] Referring to FIG. 15, after the panel holder (100) is moved so that the first part of the wire (130) is positioned below the first protrusion (112), the panel holder (100) can be rotated at a predetermined angle with the wire (130) as the rotation axis. At this time, by moving the panel holder (100) to the upper side of the support frame (110), the protrusion support part (106) can be positioned below the second protrusion (113). At this time, the wire (130) is bent, and tension of the wire (130) can be applied so that the panel holder (100) moves to the lower side of the support frame (110).

[0120] Referring to Fig. 16, the panel holder (100) can be moved downwards on the support frame (110) by the tension of the wire (130). As the panel holder (100) moves downwards on the support frame (110), the second protrusion (113) and the protrusion support (106) can be engaged with each other. When the second protrusion (113) and the protrusion support (106) are engaged, the panel holder (100) may not be separated from the support frame (110). In addition, the panel holder (100) may not be moved upwards on the support frame (110) by the tension of the wire (130). Therefore, the panel holder (100) and the support frame (110) can be maintained in a coupled state.

[0121] Fig. 17 is a cross-sectional view taken along CC of Fig. 11 with the wires removed, showing the display panel and the rear chassis together. Fig. 18 is a drawing showing the panel holder in Fig. 17 moved upward relative to the support frame. Fig. 19 is a drawing showing the panel holder after being separated forward from the support frame.

[0122] Referring to FIGS. 17 to 19, after the rear cover (50) is disassembled from the rear chassis (40), the panel holder (100) can be separated from the support frame (110) without a separate member. In addition, the display panel (10) can be separated from the rear chassis (40).

[0123] As described above, the wire (130) can be drawn out from the rear of the rear chassis (40) through the chassis hole (41) to the outside of the display device (1).

[0124] Referring to FIGS. 17 and 18, when the wire (130) is pulled out, the upward movement of the panel holder (100) with respect to the support frame (110) is not restricted. Therefore, when the display panel (10) is moved upward, the panel holder (100) together with the display panel (10) can move upward with respect to the support frame (110). When the panel holder (100) moves upward with respect to the support frame (110), the engagement between the second protrusion (113) and the protrusion support portion (106) can be released. In other words, the forward movement of the protrusion support portion (106) is not restricted by the second protrusion (113). Therefore, as illustrated in FIG. 19, the display panel (10) and the panel holder (100) can be separated from the support frame (110).

[0125] According to one embodiment, the display panel (10) and the substrate (13) attached to the display panel (10) can be separated from the rear chassis (40) without damaging the display panel (10).

[0126] An adhesive member may be provided on the upper surface and both sides of the display panel (10) to connect the upper surface and both sides of the display panel (10) to the rear chassis (40). There is no limitation on the type of the adhesive member, but it may be, for example, a double-sided tape.

[0127] After peeling off the adhesive material provided on the upper surface and both sides of the display panel (10), if the panel holder (100) provided on the lower surface of the display panel (10) is separated from the support frame (110), the display panel (10) can be separated from the rear chassis (40) without damage to the display panel (10). As described above, the rear surface of the heat dissipation sheet (20) and the front surface of the rear chassis (40) are detachable from each other, so that if the bonds located on the four sides of the display panel (10) are removed, the display panel (1) can be separated to the front surface of the rear chassis (40). Accordingly, disassembly and replacement of the display panel (10) including the self-luminous panel (11) is possible.

[0128] FIG. 20 is a drawing illustrating a display device according to one embodiment, wherein the display panel and the rear chassis are separated. FIG. 21 is a drawing illustrating a display device according to one embodiment, wherein the panel holder and the support frame are separately drawn. FIG. 22 is a drawing illustrating the panel holder and the support frame illustrated in FIG. 21 coupled to each other.

[0129] In the following, any explanation that overlaps with the above will be omitted.

[0130] Referring to FIGS. 20 to 22, the panel holder (200) and the support frame (210) according to one embodiment can be coupled and separated by sliding movement without wires or separate members.

[0131] More specifically, the panel holder (200) can be coupled to the support frame (210) by sliding relative to the support frame (210) in a first direction. Conversely, the panel holder (200) can be separated from the support frame (210) by sliding relative to the support frame (210) in a second direction opposite to the first direction. In one embodiment, the first direction can point downward, and the second direction can point upward.

[0132] The panel holder (200) can be coupled to the lower rear side of the display panel (10). The support frame (210) can be coupled to the lower front side of the rear chassis (40). By moving the display panel (10) upward relative to the rear chassis (40), the display panel (10) can be separated forward from the rear chassis (40).

[0133] Fig. 23 is an enlarged view of D of Fig. 22, showing the panel holder and the support frame combined. Fig. 24 is an enlarged view of D of Fig. 22, showing the panel holder and the support frame in a state where they can be separated from each other. Fig. 25 is a cross-sectional perspective view of Fig. 23. Fig. 26 is a cross-sectional perspective view of Fig. 24.

[0134] Referring to FIGS. 23 to 26, a panel holder (200) according to one embodiment may include a coupling protrusion (201) protruding toward a support frame (210). The coupling protrusion (201) may include a head portion (201a) having a first area, and a connecting portion (201b) having a second area smaller than the first area and connecting the head portion (201a) and the panel holder (200).

[0135] The support frame (210) may include a first hole (211) having an area larger than the first area so that the head portion (201a) of the panel holder (200) can pass through, and a second hole (212) having an area smaller than the first area and larger than the second area. The first hole (211) and the second hole (212) may be arranged in a vertical direction in succession.

[0136] By the above structure, the head portion (201a) of the coupling protrusion (201) can be inserted into the first hole (211). The head portion (201a) inserted into the first hole (211) can slide downward. When the head portion (201a) slides downward, the connection portion (201b) is inserted into the second hole (212), and since the head portion (201a) cannot pass through the second hole (212), the panel holder (200) and the support frame (210) can be coupled.

[0137] Conversely, when the panel holder (200) slides upward while the connecting portion (201b) is inserted into the second hole (212), the connecting portion (201b) is pulled out from the second hole (212) and the head portion (201a) is inserted into the first hole (211), so that the panel holder (200) can be separated forward from the support frame (210).

[0138] The above illustrates and describes specific embodiments. However, the invention is not limited to the above-described embodiments, and those skilled in the art will readily appreciate that various modifications and implementations can be made without departing from the spirit and scope of the invention as set forth in the claims below.
