[0071] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0072] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0073] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0074] The terms "first", "second" and the like are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined with "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0075] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0076] With respect to the display device in the related art, there is a technical problem that the distance between the left end of the front shell and the left side of the side panel, and the distance between the right end of the front shell and the right side of the side panel are relatively different, which has a negative impact on the appearance of the display device. The inventor has found through research that the reason is that the front shell and the support frame are generally connected by screws. During the assembly of the front shell, the front shell is easily offset relative to the support frame, resulting in a low relative position accuracy between the front shell and the back panel, which leads to a large difference in the distance between the left end of the front shell and the left side of the side panel, and between the right end of the front shell and the right side of the side panel, which has a negative impact on the appearance of the display device.

[0077] In view of this, an embodiment of the present application provides a display device, in which the front shell is set to include a front shell body, and two corner structures respectively connected to the left and right ends of the front shell body, and the corner structure can be configured to be positioned between the first side panel during the assembly of the front shell body. When assembling the front shell, the two corner structures can be first connected to the front shell body, and then the front shell body is covered on the support frame, and the corner structure is positioned between the first side panel, and then the front shell body is connected to the support frame. From the above assembly process, it can be seen that before the front shell body is connected to the support frame, the corner structure is positioned between the first side panel, which improves the relative position accuracy between the corner structure and the front shell body and the first side panel, which is conducive to reducing or eliminating the distance between the left end of the front shell and the left side of the side panel and the distance between the right end of the front shell and the right side of the side panel, thereby reducing or eliminating the negative impact on the appearance of the display device.

[0078] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only 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 creative work are within the scope of protection of this application.

[0079] The embodiment of the present application provides a display device, which may have various implementation forms, such as a television, a monitor, an electronic bulletin board, etc.

[0080] It should be noted that the front side, rear side, top side, bottom side, left side and right side described in the embodiments of the present application are all based on the orientation when the display device is viewed normally, that is, the display device is placed normally and facing the light emitting surface of the display device.

[0081] refer to Figure 1 and Figure 2, the display device of the embodiment of the present application may include a back plate 100, a support frame 200, a display panel 300 and a front shell. The back plate 100 may be configured with a housing cavity 130 having a first opening for mounting the support frame 200, the display panel 300 and the front shell, as well as other components of the display device. The support frame 200 may be connected to the back plate 100 for supporting the display panel 300. The display panel 300 is used to display images, and the display panel 300 may be a liquid crystal display (LCD) display panel 300, an organic light-emitting diode (OLED) display panel 300, or other types of display panels 300. The display panel 300 may be disposed in the housing cavity 130 and abut against the support frame 200. The front shell covers the bottom edge of the display panel 300 and the support frame 200 to protect the display panel 300 and enhance the aesthetic appearance of the display device.

[0082] The following takes the display panel 300 as an LCD display panel 300 as an example to describe the technical solution of the embodiment of the present application in detail.

[0083] refer to Figure 3 and Figure 4 The back plate 100 may include a back plate body 110 and a first side plate 120. The first side plate 120 may be connected to the left side, top side and right side of the back plate body 110, and the first side plate 120 and the back plate body 110 are surrounded by a receiving cavity 130 having a first opening.

[0084] A first supporting surface 111 may be provided on one side of the back panel body 110 located in the accommodating cavity 130. The display device may further include a backlight assembly for providing backlight for the LCD display panel 300, and the backlight assembly may be located in the accommodating cavity 130. The first supporting surface 111 may be used to support at least part of the backlight assembly. Exemplarily, the backlight assembly may be a direct-type backlight assembly or an edge-type backlight assembly, which will not be described in detail in the embodiments of the present application.

[0085] A support portion 121 may also be provided on one side of the first side panel 120 located in the accommodating cavity 130. Exemplarily, the support portion 121 may be located above the first support surface 111. The support portion 121 may surround the left side, top side and right side of the back panel body 110. A second support surface 122 may be provided on the side of the support portion 121 facing away from the back panel body 110, and the second support surface 122 is used to support the display panel 300. Exemplarily, the display panel 300 may be bonded to the second support surface 122. By providing a support portion 121 for connecting the display panel 300 on the first side panel 120, the display panel 300 can be directly connected to the back panel 100, thereby omitting the middle frame, simplifying the mechanical structure of the display device, and facilitating reducing the thickness of the display device to achieve an ultra-thin display.

[0086] The side of the first side plate 120 facing away from the back plate body 110 can be bent toward the accommodating cavity 130 and toward the back plate body 110 to form a bent portion 123. By providing the bent portion 123, the edge of the first side plate 120 can be smoothly transitioned, thereby improving the appearance of the display device.

[0087] The support portion 121 may be located on the side of the bending portion 123 facing the back panel body 110 . When the display panel 300 is connected to the support portion 121 , the display panel 300 may block the gap between the bending portion 123 and the support portion 121 to improve the appearance of the display device.

[0088] In some possible implementations of the embodiments of the present application, the side of the bending portion 123 facing the back panel body 110 can be bent toward the inside of the accommodating cavity 130 and away from the first side panel 120 to form the support portion 121. In other words, the side of the first side panel 120 facing away from the back panel body 110 can be continuously bent to form the bending portion 123 and the support portion 121. In this way, the gap between the bending portion 123 and the support portion 121 can be eliminated, the aesthetic appearance of the display device can be improved, and the connection difficulty between the support portion 121 and the first side panel 120 can be reduced, thereby improving the production efficiency of the back panel 100.

[0089] like Figure 4 As shown, the back plate 100 may further include a second side plate 140 for connecting to the support frame 200. The second side plate 140 may be connected to the bottom side of the back plate body 110 and extend in a direction away from the accommodation cavity 130.

[0090] In some possible implementations of the embodiments of the present application, the back panel body 110, the first side panel 120 and the second side panel 140 can be an integral structure. With such an arrangement, the back panel body 110, the first side panel 120 and the second side panel 140 can be formed by bending the same plate material, which has a low processing difficulty and improves the production efficiency of the back panel 100. In addition, the back panel body 110, the first side panel 120 and the second side panel 140 are an integral structure, which can improve the connection strength between the back panel body 110, the first side panel 120 and the second side panel 140, thereby improving the structural reliability of the back panel 100. Moreover, in the process of assembling the display device, there is no need to assemble the back panel body 110, the first side panel 120 and the second side panel 140, thereby improving the assembly efficiency of the display device.

[0091] refer to Figure 5 and Figure 6 , the support frame 200 can be connected to the bottom side of the back panel 100. The support frame 200 may include a first frame body 210 and a second frame body 220 connected to each other. The first frame body 210 and the second frame body 220 may both be strip-shaped structures. The first frame body 210 may be located at the bottom edge of the front side of the back panel body 110. For example, the first frame body 210 may be opposite to the bottom edge of the first support surface 111, and the backlight assembly may be pressed onto the first support surface 111 to fix the backlight assembly.

[0092] Exemplarily, the back panel 100 may be provided with at least one plug-in protrusion 150. The plug-in protrusion 150 may be located at the connection between the back panel body 110 and the second side panel 140, and extend in the direction of the first opening. A plug-in slot may be provided on the side of the first frame body 210 facing the back panel body 110, and the plug-in slot may be sleeved on the plug-in protrusion 150. The first frame body 210 and the back panel 100 may be positioned by the plug-in protrusion 150 and the plug-in slot, thereby improving the relative position accuracy between the support frame 200 and the back panel 100.

[0093] The second frame 220 may be located at the bottom side of the second side plate 140 and connected to the second side plate 140. For example, at least one snap-in protrusion 141 may be provided at the bottom side of the second side plate 140. The second frame 220 may be provided with a snap-in recess 221. The snap-in recess 221 may be a snap-in groove, or may be a snap-in groove such as Figure 5 and Figure 6 The clamping recess 221 can be clamped on the clamping protrusion 141. The clamping recess 221 and the clamping protrusion 141 that are clamped to each other can position the second frame 220 and the second side plate 140 to improve the relative position accuracy between the second frame 220 and the second side plate 140.

[0094] When assembling the support frame 200 and the back panel 100, the first frame 210 can be first crimped with the backlight assembly on the bottom edge of the first support surface 111, and then the plug-in slot can be sleeved on the plug-in protrusion 150 to position the first frame 210; then the snap-in through hole can be snap-fitted onto the snap-in protrusion 141 to position and connect the second frame 220, thereby connecting the support frame 200 to the back panel 100.

[0095] The front side of the support frame 200 may also be provided with a third support surface 211 for supporting the display panel 300. Exemplarily, the third support surface 211 may be provided on the front side of the first frame body 210. The third support surface 211 may be coplanar with the second support surface 122 to provide stable support for the display panel 300.

[0096] The third support surface 211 may be provided with a first receiving groove 212, and the first receiving groove 212 may extend along the extension direction of the first frame body 210. The support frame 200 may further include a first buffer bar (not shown in the drawings), and the first buffer bar may be accommodated in the first receiving groove 212. The display panel 300 may abut against the first buffer bar. The first buffer bar may play a role of shock absorption to protect the display panel 300. Exemplarily, the material of the first buffer bar may be rubber or foam.

[0097] The support frame 200 may also be provided with a second receiving groove 230. Exemplarily, the second receiving groove 230 may be provided at the bottom side of the second frame body 220. The second receiving groove 230 may extend in a direction perpendicular to the extension of the second frame body 220. A flexible circuit board 310 may be provided at the bottom side of the display panel 300. The flexible circuit board 310 may be accommodated in the second receiving groove 230 and bent to the side of the back plate 100 facing away from the receiving cavity 130 for fixing. The second receiving groove 230 can position the flexible circuit board 310 and can also protect the flexible circuit board 310.

[0098] refer to Figure 7 , Figure 8 and Fig. 9 , the front case 400 may include a front case body 410, and two corner structures 420 respectively connected to the left and right ends of the front case body 410. The front case body 410 may cover the front side of the support frame 200 and the bottom edge of the display panel 300, and be connected to the support frame 200. The corner structure 420 may be configured to be positioned between the side panels during the assembly of the front case body 410.

[0099] When assembling the front shell 400, the two corner structures 420 can be connected to the front shell body 410 first, and then the front shell body 410 can be covered on the support frame 200, and the corner structure 420 and the first side plate 120 are positioned, and then the front shell body 410 is connected to the support frame 200. From the above assembly process, it can be seen that before the front shell body 410 is connected to the support frame 200, the corner structure 420 and the first side plate 120 are positioned, which improves the relative position accuracy between the corner structure 420 and the front shell body 410 and the first side plate 120, which is conducive to reducing or eliminating the distance between the left end of the front shell 400 and the left side of the side plate and the distance between the right end of the front shell 400 and the right side of the side plate, thereby reducing or eliminating the negative impact on the appearance of the display device.

[0100] In addition, the corner structure 420 is highly versatile and can be connected to the front shell body 410 of different lengths, so that the front shell 400 can be used on display devices of different sizes in the same series, thereby reducing the number of molds added for making display devices of different sizes in the same series and reducing the development cost of the display devices.

[0101] refer to Fig. 9 , Fig.10 and Fig.11 The front shell body 410 may include a first plate body 411 and a second plate body 412 connected to each other, and the first plate body 411 may cover the front side of the support frame 200 and the bottom edge of the display panel 300. The second plate body 412 may cover the bottom side of the support frame 200 and be connected to the support frame 200. The front shell body 410 can shield the bottom edge of the support frame 200 and the display panel 300 to protect the bottom edge of the support frame 200 and the display panel 300. The front side of the first plate body 411 may be provided with a decorative appearance such as a brushed texture or a groove to improve the aesthetic appearance of the front shell 400, thereby improving the aesthetic appearance of the display device.

[0102] For example, the second plate 412 can be connected to the support frame 200 by screws. Figure 6As shown, the second side plate 140 may be provided with a first threaded hole 142. The second frame 220 of the support frame 200 may be provided with a first through hole 222, and the first through hole 222 is opposite to the first threaded hole 142. The second plate 412 may be provided with a second through hole 413, and the second through hole 413 is opposite to the first through hole 222. The display device may also include a first screw (not shown in the drawings), which may be sequentially inserted into the second through hole 413 and the first through hole 222, and threadedly connected to the first threaded hole 142. The second plate 412, the second frame 220 and the second side plate 140 may be connected by the first screw, that is, the front shell body 410 and the support frame 200 may be connected to the back plate 100 by the first screw, which simplifies the mechanical structure of the display device and improves the assembly efficiency of the display device.

[0103] The first plate 411 and the second plate 412 may be an integral structure. With such an arrangement, the first plate 411 and the second plate 412 may be processed by an integral molding process such as injection molding or extrusion, which is relatively easy to process; and there is no need to assemble the first plate 411 and the second plate 412, thereby improving the production efficiency of the front shell body 410. In addition, the first plate 411 and the second plate 412 are an integral structure, which may improve the connection strength between the first plate 411 and the second plate 412, thereby improving the structural reliability of the front shell body 410.

[0104] The two corner structures 420 may be respectively disposed at the left end and the right end of the front shell body 410 . A positioning groove 421 may be disposed on one side of the corner structure 420 away from the front shell body 410 , and the positioning groove 421 may abut against the first side plate 120 .

[0105] When assembling the front shell 400, the two corner structures 420 can be connected to the left and right ends of the front shell body 410 respectively, and then the front shell body 410 is covered on the support frame 200, and then the positioning grooves 421 of the two corner structures 420 are respectively made to abut against the first side plate 120 to position the two corner structures 420 and the first side plate 120, and then the front shell body 410 is connected to the support frame 200. From the above assembly process, it can be seen that before the front shell body 410 is connected to the support frame 200, the two corner structures 420 and the first side plate 120 can be positioned through the positioning grooves 421, which improves the relative position accuracy between the corner structures 420 and the front shell body 410 and the first side plate 120, which is conducive to reducing or eliminating the distance difference between the left end of the front shell 400 and the left side of the side plate and the distance difference between the right end of the front shell 400 and the right side of the side plate, thereby reducing or eliminating the negative impact on the appearance of the display device.

[0106] When the first side plate 120 forms a bent portion 123 on the side facing away from the back plate body 110, the positioning groove 421 abuts against the bent portion 123. The inner surface of the positioning groove 421 may be adapted to the outer surface of the bent portion 123. In this way, the contact area between the positioning groove 421 and the bent portion 123 may be increased, thereby improving the relative position accuracy between the corner structure 420 and the first side plate 120, and further improving the relative position accuracy between the front shell 400 and the first side plate 120.

[0107] Exemplarily, the outer surface of the bending portion 123 and the inner surface of the positioning groove 421 can both be arc-shaped surfaces. It is understandable that the outer surface of the bending portion 123 and the inner surface of the positioning groove 421 can also be other surface shapes, which will not be described in detail in the embodiment of the present application.

[0108] In some possible implementations of the present application, the materials of the front shell body 410 and the corner structure 420 can both be metal. The front shell body 410 can be made by an extrusion process, and the corner structure 420 can be made by a die-casting process.

[0109] In some related technologies, when the material of the front shell 400 is metal, the front shell body 410 is generally made by an extrusion process. Then, the two ends of the front shell body 410 are processed by a computer numerical control machine tool (Computerized Numerical Control, referred to as CNC) or manual grinding to form preset structures such as edge sealing and fillet at both ends of the front shell body 410. However, in the process of forming the preset structure, the front shell body 410 needs to be clamped and positioned multiple times. Due to the poor consistency of multiple clamping and positioning, as well as the poor consistency of manual grinding, the processing accuracy of the preset structure is low, for example, there will be problems such as the edge sealing is not smooth enough and the fillet is not round enough, which reduces the yield of the front shell 400.

[0110] Compared with the related art, the embodiment of the present application can manufacture the front shell body 410 by an extrusion process, and manufacture the corner structure 420 by a die-casting process. Compared with CNC and manual polishing processes, the die-casting process has higher processing accuracy, fewer processes, and lower costs, and can form a higher-precision preset structure on the front shell 400, thereby improving the yield of the front shell 400 and reducing the production cost of the front shell 400.

[0111] refer to Fig.11 and Fig.12, the corner structure 420 may include a first connection portion 422 and a second connection portion 423. The first connection portion 422 may be connected to the first plate body 411, and the first connection portion 422 may be provided with a positioning groove 421. The second connection portion 423 may be connected to the second plate body 412, and abut against the bottom side of the first side plate 120. The first connection portion 422 is connected to the first plate body 411, and abuts against the first side plate 120 through the positioning groove 421; the second connection portion 423 is connected to the second plate body 412, and abuts against the bottom side of the first side plate 120, so that there is a sufficiently large connection area between the corner structure 420 and the front shell body 410, thereby improving the connection reliability between the corner structure 420 and the front shell body 410.

[0112] The first connection portion 422 may have a preset structure such as edge sealing and rounded corners on the side facing away from the first plate body 411, which can improve the diversity of the appearance of the display device. It is understandable that in addition to edge sealing and rounded corners, the preset structure can also be an appearance structure of other shapes, which will not be described in detail in the embodiments of the present application.

[0113] The first connection portion 422 is connected to the first plate body 411 at one side thereof facing the first plate body 411. Fig.11 As shown, a first connecting groove 414 may be provided on one side of the first plate 411 facing the support frame 200, and the first connecting groove 414 may form a second opening at the end of the first plate 411. A first connecting protrusion 424 is provided on one side of the first connecting portion 422 facing the first plate 411, and the first connecting protrusion 424 is inserted into the first connecting groove 414 via the second opening. In the process of assembling the front shell body 410 and the corner structure 420, the first connecting protrusion 424 may be inserted into the first connecting groove 414 via the second opening, and the first plate 411 and the first connecting portion 422 are positioned and connected by the first connecting groove 414 and the first connecting protrusion 424, thereby improving the relative position accuracy between the front shell body 410 and the corner structure 420.

[0114] For example, in a plane perpendicular to the extending direction of the front shell body 410, for example Fig.11On the vertical plane in the orientation shown, the cross-sections of the first connection groove 414 and the first connection portion 422 can both be trapezoidal, and the upper base of the trapezoid, that is, the short side of the trapezoid, can face the support frame 200. In other words, the first connection groove 414 can be a dovetail groove, and the first connection portion 422 can be a dovetail protrusion inserted into the dovetail groove. In this way, when the first connection portion 422 is inserted into the first connection groove 414, the groove side wall of the first connection groove 414 can block the first connection protrusion 424 to prevent the first connection portion 422 from being separated from the first connection groove 414 as much as possible, thereby improving the connection strength between the first connection groove 414 and the first connection portion 422, thereby improving the connection reliability between the front shell body 410 and the corner structure 420.

[0115] In some possible implementations of the embodiment of the present application, a second connection groove 415 may be provided on the side of the first plate body 411 facing the support frame 200, and the second connection groove 415 may form a third opening at the end of the first plate body 411. Exemplarily, when the first plate body 411 is provided with a first connection groove 414, the third opening of the second connection groove 415 may be formed on the groove side wall of the first connection groove 414. A second connection protrusion 425 may be provided on the side of the first connection portion 422 facing the first plate body 411, and the second connection protrusion 425 is bonded to the second connection groove 415 via the third opening. In this way, by bonding the second connection protrusion 425 to the second connection groove 415, the connection strength between the first plate body 411 and the first connection portion 422 can be improved, thereby improving the connection reliability between the front shell body 410 and the corner structure 420.

[0116] The side of the second plate 412 facing the front shell body 410 can be connected to the front shell body 410. Fig.11 As shown, a third connection groove 416 may be provided on the side of the second plate 412 facing the support frame 200, and the third connection groove 416 may form a fourth opening at the end of the second plate 412. A third connection protrusion 426 may be provided on the side of the second connection portion 423 facing the second plate 412, and the third connection protrusion 426 is inserted into the third connection groove 416 via the fourth opening. In the process of assembling the front shell body 410 and the corner structure 420, the third connection protrusion 426 may be first inserted into the third connection groove 416 via the fourth opening, and the second plate 412 and the second connection portion 423 are positioned and connected by the third connection groove 416 and the third connection protrusion 426, thereby improving the relative position accuracy between the front shell body 410 and the corner structure 420.

[0117] The bottom of the third connection groove 416 may be provided with a second threaded hole 417. The third connection protrusion 426 may be provided with a third through hole 427, and the third through hole 427 may be opposite to the second threaded hole 417. The front shell 400 may further include a second screw, which may be inserted into the third through hole 427 and threadedly connected to the second threaded hole 417. In this way, the third connection protrusion 426 may be connected to the third connection groove 416 by the second screw, thereby improving the connection strength between the front shell body 410 and the corner structure 420, thereby improving the structural reliability of the front shell 400.

[0118] The front shell 400 may further include a shading member. The shading member may be disposed on the side of the corner structure 420 facing the support frame 200. For example, the shading member may be disposed on the side of the first connection portion 422 facing the support frame 200. The shading member may also be disposed on the side of the second connection portion 423 facing the support frame 200. The shading member may block or absorb the light emitted from the corner of the back plate 100 to prevent light leakage from both ends of the front shell 400 as much as possible.
