[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0033] In the prior art, with the development of the liquid crystal display industry, the size of display devices (such as televisions) is getting larger and larger. A display device is a device that can output images or tactile information, among which LCD TVs are one of the most common display devices. The upper part of the back panel of an LCD TV is exposed as the appearance surface, and electrical components are arranged behind the lower part of the back panel, and a rear shell is arranged to protect the electrical components. Figure 1 As shown, a conventional display device 2 includes a back panel 21 and a rear shell 22. The rear shell 22 is arranged in the middle of the back panel 21. A left cover plate 23 and a right cover plate 24 are respectively arranged on the left and right sides of the rear shell 22. The left cover plate 23, the right cover plate 24 and the rear shell 22 are fixedly connected to the back panel 21 by fasteners such as bolts. A terminal 221 is arranged on one side of the rear shell 22.

[0034] In this technical solution, the rear housing 22 is very small and is centrally arranged on the backlight side of the display device 2. The distance between the terminal 221 and the edge of the display device 2 is relatively far, and it is very difficult to plug and unplug the terminal 221. In particular, when the display device 2 is in a wall-mounted state, the gap between the display device 2 and the wall is relatively small, and it is difficult for the user to reach into the gap to plug and unplug the terminal 221, which affects the user experience. In addition, there are many parts, which affects the assembly efficiency.

[0035] In order to solve the technical problem in the prior art that it is difficult to plug and unplug terminals of display devices, which affects the user experience, the present application provides a display device that can easily plug and unplug terminals without being restricted by the space between the back panel and the wall, thereby greatly improving the user experience and improving assembly efficiency.

[0036] Figure 3 A display device 1 provided in an embodiment of the present application includes a back plate 11, a rear shell 12 and a first cover plate 13. The back plate 11 is provided with a backlight area 111 and a receiving groove 112 ( Figure 5 As shown in the figure, the backlight area 111 and the accommodating groove 112 are arranged in sequence along the height direction of the back plate 11, the backlight area 111 is used to accommodate the backlight module, the accommodating groove 112 is used to install electrical components such as speakers, and a first side wall 113 is arranged at the edge of the back plate 11; the rear shell 12 covers the accommodating groove 112, the central axis of the rear shell 12 is set to deviate from the central axis of the back plate 11, and the rear shell 12 is respectively provided with a second side wall 121 and a third side wall 122 on both sides in the horizontal direction, the second side wall 121 of the rear shell 12 is arranged close to the side of the first side wall 113 of the back plate 11, and the second side wall 121 of the rear shell 12 is provided with a terminal 123; the first cover plate 13 covers the accommodating groove 112, and the first cover plate 13 is arranged on the third side wall 122 of the rear shell 12.

[0037] It is understandable that the present application breaks the conventional thinking that the rear shell 12 is centered, and designs the rear shell 12 to deviate from the central axis of the back plate 11. By setting the terminal 123 on the second side wall 121 of the rear shell 12, the terminal 123 is closer to the first side wall 113 of the back plate 11. Compared with the solution where the rear shell 12 is centered, the distance between the terminal 123 and the first side wall 113 is shortened. When the display device 1 is mounted on the wall (in the wall-mounted state), the terminal 123 is within reach, and the user can easily plug and unplug the terminal 123 without reaching into the space behind the back plate 11, and will not be restricted by the space between the back plate 11 and the wall, which greatly improves the user experience. At the same time, the number of assembly parts for mounting the right cover plate on the back plate 11 in the traditional solution is reduced, and the assembly efficiency is improved.

[0038] The material of the back plate 11 can be a metal material, such as any one of an aluminum plate, an aluminum alloy plate or a galvanized steel, and is made by a stamping process. The metal material has good ductility and can protect the backlight module from being easily broken under the impact of external force. The material of the back plate 11 can also be a plastic material, such as polyimide, polycarbonate, polyethersulfone, polyethylene terephthalate, polyethylene, etc., to reduce the weight of the display device 1 and reduce the cost of the display device 1.

[0039] In some embodiments, when the backlight module is an edge-entry backlight module, the second side wall 121 of the rear shell 12 is flush with the first side wall 113 of the back plate 11. It should be noted that the first side wall 113 is generally set as an inclined surface. When the backlight module is an edge-entry backlight module, the second side wall 121 of the rear shell 12 is flush with the inner edge of the inclined surface of the first side wall 113 of the back plate 11, thereby further reducing the distance between the terminal 123 and the first side wall 113, making it more convenient for users to plug and unplug the terminal 123.

[0040] In some embodiments, Figure 5 As shown, when the backlight module is a direct-type backlight module, a second cover plate 14 covering the accommodating groove 112 is provided on the second side wall 121 of the rear shell 12, and the rear shell 12 and the second cover plate 14 are integrally provided. This embodiment is illustrated by taking the backlight module as an edge-entry backlight module as an example, because the length of the right cover plate is greatly reduced compared to the solution in which the second cover body is centered on the rear shell 12, the rear shell 12 and the second cover plate 14 are integrally provided, which can facilitate the subsequent installation of the rear shell 12 on the back plate 11, improve assembly efficiency, and effectively control the mold cost.

[0041] The rear shell 12 is provided with a first connection hole 124, and the first connection hole 124 is provided with a first fastener, and the rear shell 12 and the back plate 11 are detachably connected through the first fastener; the first cover plate 13 is provided with a second connection hole 131, and the second connection hole 131 is provided with a second fastener, and the first cover plate 13 and the back plate 11 are detachably connected through the second fastener. It should be noted that both the first fastener and the second fastener can be bolts, and the number of the first connection holes 124 can be set to multiple according to the area size of the rear shell 12, and the number of the second connection holes 131 can be set to multiple according to the length of the first cover plate 13, so as to improve the connection stability between the rear shell 12 and the back plate 11, and between the first cover plate 13 and the back plate 11.

[0042] The second cover plate 14 is provided with a third connection hole 141, and a third fastener is provided on the third connection hole 141. The second cover plate 14 and the cover plate are detachably connected through the third fastener. It should be noted that the third fastener can be a bolt, and a plurality of third connection holes 141 can be provided according to the length of the third cover plate to improve the connection stability between the second cover plate 14 and the back plate 11.

[0043] like Figure 2 As shown, since the rear shell 22 of the traditional display device 2 is centered, a hanger 25 is generally designed on the rear shell 22, and the display device 2 is mounted on the wall by cooperating with the hanger 25 and the reserved components on the wall. However, the rear shell design of the embodiment of the present application makes the overall center of gravity of the display device 1 deviate from its central axis, so the solution of mounting the hanger on the rear shell is no longer applicable. In addition, in the traditional wall-mounted solution, since the rear shell 22 itself has a certain thickness, the gap between the display device 2 and the wall surface is large after the hanger 25 is installed, which affects the aesthetic effect of the wall-mounted display.

[0044] In the embodiments of the present application, Figure 3 and Figure 4 As shown, the display device 1 further includes a hanger 15, and mounting plates 16 are respectively provided at both ends of the hanger 15 in the length direction thereof, and the length direction of the hanger 15 is parallel to the horizontal direction, and the mounting plates 16 are detachably connected to the back plate 11. By directly arranging the hanger 15 on the back plate 11, the space where the rear shell 12 protrudes from the back plate 11 can be effectively utilized, the wall-hanging gap between the back plate 11 and the wall surface can be shortened, and the aesthetic effect of wall-hanging can be improved, and the wall-hanging gap does not affect the plugging and unplugging of the terminal 123.

[0045] like Figure 6 and Figure 7 As shown, the mounting plate 16 includes a connecting plate 161, and two opposite sides of the connecting plate 161 are bent in a direction away from the back plate 11 to form a clamping plate 162. A rivet post 17 is provided on the side of the back plate 11 away from the backlight module, and a screw 18 is provided on the connecting plate 161 that is threadedly connected to the rivet post 17. Through the threaded connection of the screw 18 and the rivet post 17, the connecting plate 161 can be effectively fixed to the back plate 11, thereby ensuring the stability of the wall-mounted installation of the display device 1.

[0046] The cross section of the hanger 15 is Z-shaped, and the card plate 162 is provided with a card slot 1621 that is card-connected with the hanger 15. Through the card connection between the card plate 162 and the hanger 15, the display device 1 can effectively bear the weight.

[0047] A washer is provided between the screw 18 and the connecting plate 161 so that the side of the bracket 15 facing away from the back plate 11 is flush with the side of the rear shell 12 facing away from the back plate 11 on the vertical plane to improve the aesthetics of the wall hanging. The washer is selected according to the thickness of the rear shell 12 protruding from the back plate 11. If the thickness of the rear shell 12 protruding from the back plate 11 is small, the washer may not be provided.

[0048] In a preferred embodiment, the central axis of the hanger 15 coincides with the central axis of the back plate 11 , so that the load-bearing performance of the hanger 15 is more stable.

[0049] In the embodiments of the present application, Figure 6As shown, the display device 1 further includes a display panel 19 , and a backlight module is disposed on the backlight side of the display panel 19 for providing light source to the display panel 19 .

[0050] The display panel 19 includes an array substrate and a color filter substrate arranged opposite to each other, and a liquid crystal layer arranged between the array substrate and the color filter substrate. The liquid crystal layer includes a plurality of liquid crystal molecules. The liquid crystal molecules are usually rod-shaped and can flow like liquids, but also have certain crystal characteristics. When the liquid crystal molecules are in an electric field, their arrangement direction will change according to the change of the electric field.

[0051] Since the display panel 19 itself does not emit light, a backlight module needs to be provided to provide it with a light source with sufficient brightness and uniform distribution so that it can display images normally.
