1 is a cross-sectional view of the first structure of the display device provided by this embodiment; FIG. 2 is a partial enlarged view of I in FIG. 1; FIG. 3 is a schematic structural diagram of the back plate in FIG. 1. 1 to 3, the present embodiment provides a display device including a backplane 200 and a panel 100. The backplane 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. The bottom plate 210 and the side plate 220 jointly enclose a receiving slot 240 for installing the panel 100. At the same time, an extension part 230 is formed by bending the top end of the side plate 220 into the receiving groove 240, and the panel 100 is fixed on the extension part 230. In this embodiment, the extension 230 plays a role of supporting the panel 100 to ensure the stability of the panel 100 in a direction perpendicular to the bottom plate 210.

Wherein, the extension portion 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, only the panel 230 is fixed on the extension part 230 to complete the rapid assembly of the panel 100 and ensure the stability of the panel 100. In some examples, the panel 100 can be bonded to the extension 230. Specifically, glue can be applied to the extension part 230, and then the panel 100 is adhered to the extension part 230, so that the panel 100 is stably assembled on the back panel 200.

In this embodiment, the panel 100 is adhered to the extension portion 230 by an adhesive such as double-sided tape to ensure the stability of the panel 100 in the horizontal direction. By adhering the panel 100 to the extension part 230, while ensuring the 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.

The above-mentioned structural arrangement of the backplane 200 of this embodiment reduces the number of components of the display device, simplifies the overall structure of the display device, makes the assembly process of the display device more convenient and quicker, and also saves the manufacturing cost of the display device.

In addition, a section of extension 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 ability of the display device to resist bending and torsional deformation, thereby extending the display device’s Service life.

Continuing to refer to FIG. 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 in the direction of the bottom plate 210, the second bending portion 232 extends in the direction of the central axis of the accommodating groove 240, so that the first bending portion 231 is arranged opposite to the side plate 220, and the second bending portion The portion 232 is opposite to the bottom plate 210. When specifically assembling the panel 100, the panel 100 can be glued to the second bending portion 232, that is, the second bending portion 232 plays a role of supporting the panel 100.

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 the end of the first bending portion 231 continuing to the accommodating groove 240. It is formed by extending in the direction of the central axis. In other words, the first bending portion 231 and the second bending portion 232 are formed by bending the side plate 220 twice.

In practical applications, the top end of the side plate 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 end of the side plate 220 can be bent toward the bottom plate 210 to form a first bend. Portion 231, the bending surface formed between the first bending portion 231 and the side plate 220 is a curved surface, so as to ensure that the top of the side plate 220 is a smooth surface, thereby preventing the display device from colliding with the external environment and even displaying the external environment The device causes damage.

On this basis, continue to bend the first bending portion 231 in a direction away from the side plate 220, that is, toward the central axis of the containing groove 240 to form a second bending portion 232 for supporting the panel 100. This arrangement not only reduces the components of the display device, improves the assembly efficiency, but also further improves the production efficiency of the back plate 200, and at the same time enhances the overall mechanical strength of the back plate 200.

In order to save the space occupied by the first bending portion 231 and the second bending portion 232 in the accommodating groove 240, the first bending portion 231 of this embodiment is arranged parallel to the side plate 220 to reduce the first bending The space occupied by the second 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. The components in the display device save assembly space. In addition, the second bending portion 232 is arranged parallel to the bottom plate 210, which can also ensure the stable support of the second bending portion 232 to the panel 100.

Of course, in some examples, the extension part 230 may also be a bent part formed by bending the top end of the side plate 220 only toward the central axis of the accommodating groove 240 once, and the bent part is disposed opposite to the bottom plate 210. In other examples, the extension 230 may also be a section of protrusion directly extending on the inner wall of the side plate 220, and the molding method of the extension 230 is not limited here.

Referring to FIG. 3, the back panel 200 of the display device of this embodiment includes three side panels connected in sequence. Specifically, on the three consecutively connected sides of the bottom plate 210 of the back plate 200, there are three sub-side plates extending in a direction away from the bottom plate 210. The three sub-side plates surround a rectangular frame structure with openings, so that the panel 100 has One side of the circuit interface extends from the opening to the receiving slot 240.

For the convenience of explanation, in this embodiment, the three consecutive sub-side panels from left to right in FIG. 3 are named the left side panel 221, the middle side panel 222, and the right side panel 223 in sequence.

In order to ensure that the three sides of the panel 100 can be stably supported on the back plate 200, in this embodiment, an extension 230 may be formed on each side plate 220, that is, on the left side plate 221, the middle side The top ends of the plate 222 and the right side plate 223 are both bent into the containing groove 240 to form an extension 230. When assembling, the three sides of the panel 100 are correspondingly supported on the extensions 230 on the three side plates 220 to complete the fixing of the panel 100 in the vertical direction. Of course, this embodiment is only one example of possible implementation, and it does not exclude that the extension 230 is formed only on any one of the left side plate 221, the middle side plate 222, and the right side plate 223 or on both side plates 220. Example.

Hereinafter, the extension part 230 includes the first bending part 231 and the second bending part 232 as an example for description.

Fig. 4 is a partial enlarged view of the first structure at II in Fig. 3. 3 and 4, in this embodiment, two adjacent sub-side plates are bent along the length direction to form a first bending portion 231, in other words, both ends of the first bending portion 231 extend respectively To the two ends of each sub-side plate, and the second bending portion 231 on each sub-side plate has a different arrangement. In some examples, the two ends of the second bending portion 232 on each sub-side panel extend along the lengthwise ends of the sub-side panel to the two second bending portions 232 on the two adjacent sub-side panels. It is connected to ensure that each position of the three sub-side plates along the length direction has the second bent portion 232, so as to ensure the supporting effect of the panel 100.

For example, the two ends of the second bending portion 232 on the middle side plate 222 may respectively extend to the left and right ends of the middle side plate 222. At this time, the left end of the second bending portion 232 of the left side plate 221 extends to the left side. The left end of the plate 221 and the right end of the second bending portion 232 of the left side plate 221 extend to be connected to the second bending portion 232 of the middle side plate 222. Similarly, the second bending portion 232 on the right side plate 223 The right end extends to the right end of the right side plate 223, and the left end of the second bending portion 232 on the right side plate 223 extends to be connected to the second bending portion 232 of the middle side plate 222. Wherein, the connection of the second bending portion 232 of the three extension portions can be connected by welding.

Fig. 5 is a partial enlarged view of the second structure at II in Fig. 3; Fig. 6 is a cross-sectional view of A-A in Fig. 6; Fig. 7 is an exploded view of Fig. 5. As shown in FIG. 4 and FIG. 7, in some other examples, the two second bending portions 232 on the two adjacent sub-side panels are not connected. For example, when the two ends of the second bending portion 232 on the middle side plate 222 are respectively located at the two ends of the middle side plate 222, the right end of the second bending portion 232 on the left side plate 221 and the middle side plate 222 have A certain distance; or, there is a certain distance between the right end of the second bending portion 232 on the left side plate 221 and the middle side plate 222, and the left end of the second bending portion 232 on the middle side plate 222 and the left side plate 221 There is also a certain distance between them. In other words, the second bent portion 232 on the left side plate 221 and the second bent portion 232 on the middle side plate 222 do not extend to the clamp between the left side plate 221 and the middle side plate 222. Corner.

The two ends are connected to the left end of the second bending part 232 on the middle side plate 222, so as to realize the connection between the left side plate 221 and the second bending part 232 on the middle side plate 222.

As shown in FIGS. 5 and 7, when the second bent portion 232 on the left side plate 221 and the second bent portion 232 on the middle side plate 222 do not extend to the clamp between the left side plate 221 and the middle side plate 222 At the corner, the transition bracket 300 can be correspondingly arranged at the corner between the left side plate 221 and the middle side plate 222, and a part of the transition bracket 300 can be extended to the left side plate 221, and the second side of the left side plate 221 The bending portion 232 is connected, so that another part of the transition bracket 300 extends to the middle side plate 222 and is connected to the second bending portion 232 on the middle side plate 222, thereby realizing the connection of two adjacent extension portions.

Specifically, referring to FIG. 7, the transition bracket 300 may include a first part 310 and a second part 320 perpendicular to the first part 310. Wherein, the first part 310 and the second part 320 are respectively detachably mounted on two adjacent side plates 220, and the first part 310 is connected to an extension 230 on one of the two adjacent side plates 220, The second part 320 is connected to the extension 230 on the other side plate 220 of the two adjacent side plates 220. For example, 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 corner between the left side plate 221 and the middle side plate 222, the transition bracket The top angle formed between the first part 310 and the second part 320 of 300 is correspondingly installed in the included angle between the left side plate 221 and the middle side plate 222, the first part 310 is correspondingly installed on the left side plate 221, and the One end of the part 310 away from the second part 320 is connected to the second bending portion 232 on the left side plate 221, the second part 320 is correspondingly installed on the middle side plate 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 plate 222 is connected to ensure the stability of the panel 100 at the angle between the left side plate 221 and the middle side plate 222.

The included angle between the first part 310 and the second part 320 is set at a right angle to ensure that the structure of the transition bracket 300 matches the structure at the included angle formed between the two adjacent side plates 220, thereby ensuring The stability of the transition bracket 300 at the included angle position.

In this embodiment, a transition bracket 300 is provided at the junction of two adjacent sub-side plates, so that the second bent portions 232 on the two adjacent sub-side plates at the junction are connected by the transition bracket 300, thereby reducing The butt accuracy of the second bending portion 232 of two adjacent sub-side panels avoids the inconsistency of the splicing height or the occurrence of splicing gaps when the second bending portions 232 of the two adjacent sub-side panels are directly spliced, thereby realizing the The stable connection between the second bending portions 232 on the two adjacent sub-side panels ensures the stability of the support for the panel 100.

Fig. 8 is a schematic structural diagram of the transition bracket in Fig. 5. Referring to FIGS. 6 to 8, the transition bracket 300 of this embodiment may specifically include a main board 330 arranged horizontally and a sub-board 340 extending downward from the main board 330. After the transition bracket 300 is assembled on the back plate 200, the main board 330 and the bottom plate 210 of the transition bracket 300 are disposed opposite to each other, the sub board 340 is disposed opposite to the side board 220, and the sub board 340 is located between the main board 330 and the bottom plate 310. Wherein, the auxiliary board 340 is adhered to the inner wall of the side board 220 to realize the connection between the transition bracket 300 and the back board 200, thereby ensuring the stability of the transition bracket 300.

The main board 330 of the transition bracket 300 includes a main body portion 331 and connecting portions 332 located at both ends of the main body portion 331. The extension portions 230 of two adjacent sub-side boards are respectively overlapped on the connecting portion 332 of the main board 300. When the extension portion 230 includes the first bending portion 231 and the second bending portion 232, specifically, the second bending portions 232 of two adjacent sub-side plates are respectively overlapped on the connecting portion 332 of the main board 300.

Specifically, referring to FIG. 8, the surface of the connecting portion 332 is lower than the surface of the main body portion 331, so that after the portion of the second bending portion 232 of the extension portion 230 overlaps the connecting portion 332, it is possible to reduce It takes up space in the vertical direction to avoid affecting the stability of the panel 110 provided on the extension 230.

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, that is, the bottom surface of the connecting portion 332 is also lower than the bottom surface of the main body portion 331, thereby ensuring the thickness of the connecting portion 332. When the connecting portion 332 is specifically manufactured, the thickness of the connecting portion 332 may be the same as the thickness of the main body portion 331.

Further, after the second bending portion 232 of the extension portion 230 is overlapped on the connecting portion 332, the top surface of the second bending portion 232 is flush with the top surface of the main body portion 331, so that the second bending portion 232 After being connected to the transition bracket 300, the two surfaces are on the same horizontal plane on the surface that faces the accommodating groove 240, so as to ensure 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 bending portion 232 and the top surface of the main body portion 331 are both surfaces facing away from the bottom plate 210.

The two ends of the supporting plate 350 are respectively located on the main board 331 and the bottom board 210 to stably support the main board 331, thereby improving the The bearing capacity of the main board 331 to the panel 100, and at the same time, the supporting board 350 is also connected with the sub board 340 to ensure the stability of the sub board 340.

In the specific arrangement, the number of the supporting plates 350 is multiple, and the multiple supporting plates 350 are arranged at intervals along the extending direction of the main board 331 to further improve the supporting effect of the main board 331 on the panel 100. It can be understood that the number of the support plates 350 is not limited here, and it can be 4, 6, or 8, etc., and can be adjusted according to the length of the main board 331.

The above example is the specific arrangement when the extension part 230 includes the first bending part 231 and the second bending part 232. It is understandable that when the extension part 230 of this embodiment is only a bent part formed by bending the top end of the side plate 220 only toward the central axis of the accommodating groove 240, the extension part 230 is opposite to the bottom plate 210. The setting method of the second bending portion 232 is the same as the setting method of the second bending portion 232. For details, please refer to the description of the setting method of the second bending portion 232 above, which will not be repeated here.
