[0067] Figure 1 is a cross-sectional view of a first structure of a display device provided in this embodiment; Figure 2 yes Figure 1 A partial enlarged view of point I in the middle; Figure 3 yes Figure 1 Schematic diagram of the structure of the mid-back plate. Figures 1 to 3As shown, this embodiment provides a display device, including a back plate 200 and a panel 100, wherein the back plate 200 includes a bottom plate 210 and a side plate 220 extending from the bottom plate 210 in a direction away from the bottom plate 210, and the bottom plate 210 and the side plate 220 together enclose a receiving groove 240 for mounting the panel 100. At the same time, an extension portion 230 is formed at the top of the side plate 220 and bent into the receiving groove 240, and the panel 100 is fixed on the extension portion 230. In this embodiment, the extension portion 230 plays a role in supporting the panel 100, ensuring the stability of the panel 100 in a direction perpendicular to the bottom plate 210.

[0068] The extension 230, the side plate 220 and the bottom plate 210 are integrally formed into the back plate 200. When the display device is specifically assembled, the panel 100 can be quickly assembled by simply fixing the panel 230 on the extension 230, and the stability of the panel 100 can also be ensured. In some examples, the panel 100 can be bonded to the extension 230. Specifically, glue can be applied to the extension 230, and then the panel 100 can be bonded to the extension 230, so that the panel 100 can be stably assembled on the back plate 200.

[0069] In this embodiment, the panel 100 is bonded to the extension part 230 by an adhesive such as a double-sided adhesive to ensure the horizontal stability of the panel 100. By bonding the panel 100 to the extension part 230, while ensuring a stable connection between the panel 100 and the extension part 230, the connection method is simplified and the thickness in the vertical direction is reduced.

[0070] The above-mentioned structural arrangement of the back plate 200 of the present embodiment reduces the number of parts of the display device, simplifies the overall structure of the display device, makes the assembly process of the display device more convenient and quick, and also saves the manufacturing cost of the display device.

[0071] In addition, an extension portion 230 extends from the side plate 220 of the back plate 200 , which increases the cross-sectional area of ​​the back plate 200 , thereby enhancing the display device's ability to resist bending and torsional deformation, thereby extending the service life of the display device.

[0072] Continue to refer to Figure 2 The extension portion 230 of this embodiment may include a first bending portion 231 and a second bending portion 232. The first bending portion 231 extends toward the bottom plate 210, and the second bending portion 232 extends toward the central axis of the receiving groove 240, so that the first bending portion 231 is arranged opposite to the side plate 220, and the second bending portion 232 is arranged opposite to the bottom plate 210. When the panel 100 is assembled, the panel 100 can be bonded to the second bending portion 232, that is, the second bending portion 232 plays the role of supporting the panel 100.

[0073] It can be understood that the first bending portion 231 is formed by bending the top end of the side plate 220 toward the bottom plate 210, and the second bending portion 232 is formed by extending the end of the first bending portion 231 toward the central axis of the receiving groove 240. In other words, the first bending portion 231 and the second bending portion 232 are formed by bending the side plate 220 twice.

[0074] In actual applications, the top of the side panel 220 is generally exposed to the outside. Therefore, in order to ensure that the outer surface of the entire display device is smooth, the top of the side panel 220 can be bent toward the bottom plate 210 to form a first bending portion 231. The bending surface formed between the first bending portion 231 and the side panel 220 is a curved surface, thereby ensuring that the top of the side panel 220 is a smooth surface, thereby preventing the display device from colliding with the external environment and causing damage to the external environment or even the display device.

[0075] On this basis, the first bent portion 231 is further bent away from the side plate 220, that is, toward the central axis of the receiving groove 240, to form a second bent portion 232 to support the panel 100. This arrangement not only reduces the number of parts of the display device and improves assembly efficiency, but also further improves the manufacturing efficiency of the back plate 200, and also enhances the overall mechanical strength of the back plate 200.

[0076] In order to save the space occupied by the first bending portion 231 and the second bending portion 232 in the receiving groove 240, the first bending portion 231 of this embodiment is arranged parallel to the side plate 220 to reduce the space occupied by the first bending portion 231 in the horizontal direction; the second bending portion 232 is arranged parallel to the bottom plate 210 to save the space occupied by the second bending portion 232 in the vertical direction, thereby saving assembly space for the components in the display device arranged in the receiving groove 240. In addition, the second bending portion 232 is arranged parallel to the bottom plate 210, which can also ensure that the second bending portion 232 stably supports the panel 100.

[0077] Of course, in some examples, the extension portion 230 may also be a bent portion formed by bending the top end of the side plate 220 only once toward the central axis direction of the receiving groove 240, and the bent portion is arranged opposite to the bottom plate 210. In other examples, the extension portion 230 may also be a protruding portion directly extending from the inner wall of the side plate 220, and the molding method of the extension portion 230 is not limited here.

[0078] Reference Figure 3As shown, the back panel 200 of the display device of this embodiment includes three sub-side panels connected in sequence. Specifically, three sub-side panels extend in a direction away from the bottom plate 210 on three sides connected in sequence of the bottom plate 210 of the back panel 200, and the three sub-side panels enclose a rectangular frame structure with an opening, so that the side of the panel 100 with the circuit interface extends from the opening to the accommodating groove 240.

[0079] For the convenience of explanation, this embodiment will Figure 3 The three consecutive sub-side panels from left to right are named left side panel 221, middle side panel 222 and right side panel 223 respectively.

[0080] In order to ensure that the three sides of the panel 100 can be stably supported on the back panel 200, in this embodiment, an extension portion 230 can be formed on each side panel 220, that is, the top ends of the left side panel 221, the middle side panel 222 and the right side panel 223 are bent into the accommodating groove 240 to form an extension portion 230. During assembly, the three sides of the panel 100 are supported on the extension portions 230 on the three side panels 220 to complete the fixation of the panel 100 in the vertical direction. Of course, this embodiment is only one example of possible implementation, and does not exclude the example of forming the extension portion 230 on only one or two side panels 220 among the left side panel 221, the middle side panel 222 and the right side panel 223.

[0081] The following description will be specifically made by taking an example that the extending portion 230 includes the first bending portion 231 and the second bending portion 232 .

[0082] Figure 4 yes Figure 3 A partial enlarged view of the first structure at II in the figure. Figure 3 and Figure 4 As shown, in this embodiment, two adjacent sub-side panels are bent along the length direction to form a first bent portion 231. In other words, the two ends of the first bent portion 231 extend to the two ends of each sub-side panel respectively, and the second bent portion 231 on each sub-side panel has a different arrangement. In some examples, the two ends of the second bent portion 232 on each sub-side panel extend along the two ends of the length direction of the sub-side panel until the two second bent portions 232 on the two adjacent sub-side panels are connected, so as to ensure that the three sub-side panels have the second bent portion 232 at each position along the length direction, thereby ensuring the support effect on the panel 100.

[0083] For example, the two ends of the second bent portion 232 on the middle side plate 222 can extend to the left and right ends of the middle side plate 222, respectively. In this case, the left end of the second bent portion 232 of the left side plate 221 extends to the left end of the left side plate 221, and the right end of the second bent portion 232 of the left side plate 221 extends to connect with the second bent portion 232 of the middle side plate 222. Similarly, the right end of the second bent portion 232 on the right side plate 223 extends to the right end of the right side plate 223, and the left end of the second bent portion 232 on the right side plate 223 extends to connect with the second bent portion 232 of the middle side plate 222. The connection of the second bent portions 232 of the three extensions can be achieved by welding.

[0084] Figure 5 yes Figure 3 A partial enlarged view of the second structure at II in the middle; Figure 6 yes Figure 5 AA section view; Figure 7 yes Figure 5 Exploded diagram of . Figure 4 and Figure 7 As shown, in some other examples, the two second bent portions 232 on two adjacent sub-side panels are not connected. For example, when the two ends of the second bent portion 232 on the middle side panel 222 are respectively located at the two ends of the middle side panel 222, there is a certain distance between the right end of the second bent portion 232 on the left side panel 221 and the middle side panel 222; or, there is a certain distance between the right end of the second bent portion 232 on the left side panel 221 and the middle side panel 222, and there is also a certain distance between the left end of the second bent portion 232 on the middle side panel 222 and the left side panel 221. In other words, the second bent portion 232 on the left side panel 221 and the second bent portion 232 on the middle side panel 222 do not extend to the angle between the left side panel 221 and the middle side panel 222.

[0085] Reference Figure 5 and Figure 6 As shown, to ensure stable support for the panel 100, the display device of this embodiment also includes at least one transition bracket 300 detachably installed at the connection between two adjacent sub-side panels, and the extensions 230 on the two adjacent sub-side panels are connected through the transition bracket 300.

[0086] Specifically, when the two ends of the second bending portion 232 on the middle side panel 222 are respectively located at the two ends of the middle side panel 222, and there is a certain distance between the right end of the second bending portion 232 on the left side panel 221 and the middle side panel 222, the transition bracket 300 can be installed on the left side panel 221, and the first end of the transition bracket 300 is connected to the right end of the second bending portion 232 on the left side panel 221, and the second end of the transition bracket 300 is connected to the left end of the second bending portion 232 on the middle side panel 222, thereby realizing the connection between the second bending portion 232 on the left side panel 221 and the middle side panel 222.

[0087] like Figure 5 and Figure 7 As shown, when the second bending portion 232 on the left side plate 221 and the second bending portion 232 on the middle side plate 222 do not extend to the angle between the left side plate 221 and the middle side plate 222, the transition bracket 300 can be correspondingly set at the angle between the left side plate 221 and the middle side plate 222, and a part of the transition bracket 300 is extended to the left side plate 221 and connected with the second bending portion 232 of the left side plate 221, and the other part of the transition bracket 300 is extended to the middle side plate 222 and connected with the second bending portion 232 on the middle side plate 222, thereby realizing the connection of two adjacent extension portions.

[0088] Specifically, refer to Figure 7 As shown, the transition bracket 300 may include a first portion 310 and a second portion 320 perpendicular to the first portion 310. The first portion 310 and the second portion 320 are detachably mounted on two adjacent side panels 220, respectively, the first portion 310 is connected to the extension portion 230 on one of the two adjacent side panels 220, and the second portion 320 is connected to the extension portion 230 on the other of the two adjacent side panels 220. For example, when the second bending portion 232 on the left side panel 221 and the second bending portion 232 on the middle side panel 222 do not extend to the angle between the left side panel 221 and the middle side panel 222, the top angle formed between the first part 310 and the second part 320 of the transition bracket 300 is correspondingly installed within the angle between the left side panel 221 and the middle side panel 222, the first part 310 is correspondingly installed on the left side panel 221, and the end of the first part 310 away from the second part 320 is connected to the second bending portion 232 on the left side panel 221, the second part 320 is correspondingly installed on the middle side panel 222, and the end of the second part 320 away from the first part 310 is connected to the second bending portion 232 on the middle side panel 222, thereby ensuring the stability of the panel 100 at the angle between the left side panel 221 and the middle side panel 222.

[0089] Among them, the angle between the first part 310 and the second part 320 is set to a right angle to ensure that the structure of the transition bracket 300 matches the structure at the angle formed between two adjacent side panels 220, thereby ensuring the stability of the transition bracket 300 at the angle position.

[0090] In this embodiment, a transition bracket 300 is set at the connection between two adjacent sub-side panels, so that the second bent portions 232 of the two adjacent sub-side panels at the connection are connected through the transition bracket 300, thereby reducing the docking accuracy of the second bent portions 232 of the two adjacent sub-side panels, avoiding the phenomenon of inconsistent height at the splicing point or splicing gaps when the second bent portions 232 of the two adjacent sub-side panels are directly spliced, thereby achieving a stable connection between the second bent portions 232 of the two adjacent sub-side panels, and ensuring the support stability of the panel 100.

[0091] Figure 8 yes Figure 5 Schematic diagram of the structure of the middle transition bracket. Figures 6 to 8 As shown, the transition bracket 300 of this embodiment may specifically include a horizontally arranged main plate 330 and a sub-plate 340 extending downward from the main plate 330. When the transition bracket 300 is assembled on the back plate 200, the main plate 330 of the transition bracket 300 is arranged opposite to the bottom plate 210, the sub-plate 340 is arranged opposite to the side plate 220, and the sub-plate 340 is located between the main plate 330 and the bottom plate 310. The sub-plate 340 is bonded to the inner wall of the side plate 220 to achieve the connection between the transition bracket 300 and the back plate 200, thereby ensuring the stability of the transition bracket 300.

[0092] The main board 330 of the transition bracket 300 includes a main body 331 and connecting parts 332 at both ends of the main body 331, and the extension parts 230 of two adjacent sub-side panels are respectively overlapped on the connecting parts 332 of the main board 300. When the extension part 230 includes a first bending part 231 and a second bending part 232, specifically, the second bending parts 232 of two adjacent sub-side panels are respectively overlapped on the connecting parts 332 of the main board 300.

[0093] Specifically, refer to Figure 8 As shown, the surface of the connecting portion 332 is lower than the surface of the main body 331, so that after the second bending portion 232 of the extension portion 230 is partially overlapped on the connecting portion 332, the occupied space in the vertical direction can be reduced, thereby avoiding affecting the stability of the panel 110 set on the extension portion 230.

[0094] In addition, in order to enhance the mechanical strength of the connecting portion 332, the surface of the connecting portion 332 facing the bottom plate 210, i.e., the bottom surface of the connecting portion 332, is also lower than the bottom surface of the main body 331, thereby ensuring the thickness of the connecting portion 332. When the connecting portion 332 is specifically manufactured, its thickness can be consistent with the thickness of the main body 331.

[0095] Further, when the second bent portion 232 of the extension portion 230 overlaps the connection portion 332, the top surface of the second bent portion 232 is flush with the top surface of the main body 331, so that after the second bent portion 232 is connected to the transition bracket 300, the two are on the same horizontal plane on the surface facing the opening of the accommodating groove 240, thereby ensuring that the bottom surface of the panel 100 is in close contact with the second bent portion 232 and the main board 331 of the transition bracket 300. It should be noted that the top surface of the second bent portion 232 and the top surface of the main body 331 are both surfaces facing away from the bottom plate 210.

[0096] Continue to refer to Figure 8 As shown, the transition bracket 300 of this embodiment may also include a support plate 350, and the two ends of the support plate 350 are respectively located on the main board 331 and the bottom plate 210 to provide stable support for the main board 331, thereby improving the bearing capacity of the main board 331 on the panel 100. At the same time, the support plate 350 is also connected to the sub-board 340 to ensure the stability of the sub-board 340.

[0097] In the specific configuration, the number of the support plates 350 is multiple, and the multiple support plates 350 are spaced apart along the extension direction of the main board 331 to further improve the supporting effect of the main board 331 on the panel 100. It is understandable that the number of the support plates 350 is not limited here, and can be 4, 6 or 8, etc., which can be adjusted according to the length of the main board 331.

[0098] The above example is a specific arrangement when the extension portion 230 includes a first bending portion 231 and a second bending portion 232. It can be understood that when the extension portion 230 of this embodiment is only a bending portion opposite to the bottom plate 210 formed by bending the top end of the side plate 220 only once toward the central axis direction of the accommodating groove 240, the arrangement of the extension portion 230 is the same as the arrangement of the second bending portion 232, and the specifics can be referred to the above description of the arrangement of the second bending portion 232, which will not be repeated here.

[0099] Reference Figure 1 and Figure 2As shown, the first structure of the display device of this embodiment is a direct-type structure. In practical applications, the display device further includes a reflector 400, a diffuser 500 and a film 600. The reflector 400, the diffuser 500 and the film 600 are stacked between the panel 100 and the bottom plate 210, and the reflector 400, the light guide plate 500 and the film 600 are sequentially arranged in a direction away from the bottom plate 210.

[0100] Specifically, the reflective sheet 400 is disposed on the surface of the bottom plate 210, the diffuser 500 is disposed on the surface of the reflective sheet 400 away from the bottom plate 210, and the film 600 is disposed on the surface of the light guide plate 500 away from the reflective sheet 400, and all three are located below the panel 100. During assembly, the reflective sheet 400, the diffuser 500, and the film 600 are all located between the bottom plate 210 of the back plate 200 and the second bending portion 232.

[0101] In order to improve the light beam concentrating effect of the diffuser 500, the bottom plate 210 is symmetrically provided with two parts along the central axis, wherein any one of the parts includes a first bottom plate 211, a transition portion 212 and a second bottom plate 213 connected in sequence, the first bottom plate 211 is lower than the second bottom plate 213, and the transition portion 212 is an inclined surface of the receiving groove 240 in the back plate 200, so as to improve the aesthetic effect of the appearance of the display device. The reflective sheet 400 located above the bottom plate 210 includes a first plane portion, an inclined surface portion and a second plane portion located at both ends, which are correspondingly provided on the first bottom plate 211, the transition portion 212 and the second bottom plate 213, and the first plane portion is lower than the second plane portion, and the inclined surface portion is consistent with the inclination direction of the transition portion 212 of the bottom plate 210.

[0102] During assembly, both ends of the diffuser plate 500 are respectively overlapped on the surface of the second plane portion of the reflector sheet 400 away from the second bottom plate 223, and the middle portion of the diffuser plate 500 is located above the first plane portion of the reflector sheet 400 away from the first bottom plate 211. Since the first bottom plate 211 of the bottom plate 210 is lower than the second bottom plate 213, a certain distance is formed between the middle portion of the diffuser plate 500 disposed above the first bottom plate 211 and the first bottom plate 211 of the bottom plate 210, thereby effectively improving the light beam concentrating effect of the diffuser plate 500, so that the display brightness of the panel 100 of the display device is enhanced.

[0103] It should be noted that the provision of the extension portion 230 of the present embodiment reduces the opening size of the receiving groove 240, and therefore, the provision length of the extension portion 230 in the horizontal direction can be adjusted on the basis of ensuring that the reflector 400, the diffuser 500, the diaphragm 600 and other components can be assembled between the extension portion 230 and the bottom plate 210. When the extension portion 230 includes the first bending portion 231 and the second bending portion 232, the provision length of the second bending portion 232 in the horizontal direction can be adjusted according to the sizes of the reflector 400, the diffuser 500 and the diaphragm 600.

[0104] Fig. 9 1 is a partial cross-sectional view of the second structure of the display device of this embodiment. The second structure of the display device is an edge-entry structure, that is, the above-mentioned improvement on the display device of the direct-type structure is also applicable to the display device of the edge-entry structure. Specifically, in the edge-entry structure, a reflective sheet 400, a light guide plate 700 and a film 600 are stacked in sequence from bottom to top between the panel 100 and the bottom plate 210.

[0105] Continue to refer to Fig. 9 During assembly, the top surface of the uppermost membrane 600 is flush with or lower than the top surface of the second bending portion 232 to ensure that the membrane 600 does not affect the stability of the panel 100 in the vertical direction. The top surface of the membrane 600 specifically refers to the surface of the membrane 600 that is away from the bottom plate 210. Similarly, the top surface of the second bending portion 232 refers to the surface of the second bending portion 232 that is away from the bottom plate 210.
