DETAILED DESCRIPTION

[0050] 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 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.

[0051] Current display devices feature a wide variety of innovative products, short development cycles, and customer-specified appearance dimensions. For some display devices, customers usually have two delivery forms: flat display modules and curved display modules of the same size.

[0052] For flat display modules, in order to meet the needs of customers in different scenarios, the length of the printed circuit board (PCB) of the display module is different, and the boundary lines of the module appearance are different. Each change will require a new mold to update the appearance size to cope with the iterative update of the product, resulting in a waste of resources.

[0053] In view of this, an embodiment of the present application provides a display module. Figure 1 FIG. 1 shows a schematic diagram of the structure of a circuit board and a backplane in a display module proposed in an embodiment of the present application. Figure 1 As shown, the display module includes: a backplane 1, and a circuit board 2 arranged on one side of the backplane 1, the orthographic projections of the backplane 1 and the circuit board 2 on a plane parallel to the backplane 1 do not overlap, and the backplane 1 and the circuit board 2 form a flat display module. There is a gap between the backplane 1 and the circuit board 2.

[0054] In the embodiment of the present application, Figure 2A schematic top view of a connection structure between a circuit board and a back plate in a display module according to an embodiment of the present application is shown. Figure 3 FIG. 1 shows one of the side views of a connection structure between a circuit board and a back plate in a display module proposed in an embodiment of the present application. Figure 2 and Figure 3 As shown, at least one first fixing structure 21 is provided on the back panel 1, and the first fixing structure 21 includes a plurality of slide grooves 212, and the plurality of slide grooves 212 are arranged at intervals along a first direction, and the first direction is the arrangement direction of the orthographic projections of the back panel 1 and the circuit board 2 on the plane where the back panel 1 is located; at least one second fixing structure 22 is provided on the circuit board 2, and the second fixing structure 22 includes a plurality of fixing grooves 222 arranged at intervals, and in the first direction, at least two fixing grooves 222 are at different distances from the back panel 1.

[0055] In the embodiment of the present application, the first fixing structure 21 on the back panel 1 is connected to the circuit board 2 through the slide groove 212, and the second fixing structure 22 on the circuit board 2 is connected to the back panel 1 through the fixing groove 222. Among them, since the multiple slide grooves 212 on the first fixed structure 21 are arranged at intervals along the first direction, different slide grooves 212 have different distances from the circuit board 2 along the first direction; in the first direction, at least two fixed grooves 222 on the circuit board 2 have different distances from the back panel 1, so that when different slide grooves 212 are fixedly connected with different fixed grooves 222, the distances between the back panel 1 and the circuit board 2 along the first direction are different. Therefore, when the back panel 1 and the circuit board 2 are connected based on the first fixed structure 21 and the second fixed structure 22, the distances between the different back panel 1 and the circuit board 2 can be determined according to product requirements or models, thereby effectively avoiding the need to redesign the connection structure between the back panel 1 and the circuit board 2 due to different product models. Through the first fixed structure 21 and the second fixed structure 22 provided in the embodiment of the present application, compatible design of display modules of different models can be achieved, which greatly simplifies the product process, saves manpower and material resources, and reduces production costs.

[0056] In the embodiment of the present application, the display module further includes a connector 23, and the back plate 1 and the circuit board 2 are fixedly connected via the connector 23. Specifically, Fig.11 FIG. 1 shows a schematic diagram of a structure of a connecting member in a display module proposed in an embodiment of the present application. Fig.11As shown, the connector 23 is provided with a first fixing portion 51 and a second fixing portion 52, the first fixing portion 51 is fixedly connected to any one of the slide slots 212 of the first fixing structure 21, and the second fixing portion 52 is fixedly connected to any one of the fixing slots 222 of the second fixing structure 22. Since different slide slots 212 have different distances from the circuit board 2, the connector 23 is fixedly connected to different slide slots 212 and different fixing slots 222, respectively, so that different distances are formed between the back plate 1 and the circuit board 2 after connection to match different product models or customer needs.

[0057] In some optional embodiments, Figure 5 FIG. 1 shows a top view of a first fixing structure provided on a back plate of a display module according to an embodiment of the present application. Figure 5 As shown, the first fixing structure 21 includes a first slide 211, the first slide 211 extends along the first direction, and the first slide 211 is configured to provide a path for the first fixing portion 51 to move from one slide slot 212 to another slide slot 212. The edge of the first slide 211 extending along the first direction protrudes along the second direction to form the plurality of slide slots 212, and the second direction is a direction perpendicular to the first direction on the plane where the back plate 1 is located. Optionally, each of the slide slots 212 also includes a marking line extending along the second direction, and the marking line is used to locate the position of each of the slide slots 212, so as to better confirm the slide slot 212 connected to the connector 23 and improve the user experience.

[0058] In some optional embodiments, in order to increase the distance range between the slide groove 212 on the back panel 1 and the circuit board 2, the edge of the first slide 211 extending along the first direction includes a first edge and a second edge arranged opposite to each other, and the multiple slide grooves 212 include a first slide groove 31 protruding from the first edge along the second direction, and a second slide groove 32 protruding from the second edge along the second direction, and the first slide groove 31 and the second slide groove 32 extend back to back in the second direction.

Optionally, in each of the first fixing structures, the number of the first slide grooves 31 and the number of the second slide grooves 32 are the same.

[0060] In some optional embodiments, the slide groove 212 includes an end portion 2121 located away from the first slideway 211 and a connecting portion 2122 connecting the end portion 2121 and the first slideway 211, and the end portion 2121 is configured to be fixedly connected with the first fixing portion 51 by interference fit. Optionally, the component on the first fixing portion 51 for fixing with the slide groove 212 is a circular fixing structure, the end portion 2121 is a circular arc-shaped slide groove with a diameter substantially the same as the diameter of the circular fixing structure, and the connecting portion 2122 is a linear slide groove with a width substantially the same as the diameter of the circular fixing structure.

[0061] Optionally, in order to ensure that the first fixing portion 51 can move from one slide groove 212 to another slide groove 212 through the first slide channel 211 , the width of the first slide channel 211 along the second direction is greater than or equal to the width of the slide groove 212 along the first direction.

[0062] Exemplarily, each of the first fixed structures 21 includes 10 slide grooves 212, wherein the slide grooves 212 include 5 first slide grooves 31 and 5 second slide grooves 32, the first slide grooves 31 and the second slide grooves 32 are alternately arranged along the first direction, and the center spacing between adjacent slide grooves 212 along the first direction (that is, the spacing between the engraving lines corresponding to adjacent slide grooves 212 along the first direction) is 0.5 mm.

[0063] In some optional embodiments, Figure 6 FIG. 2 is a side view schematic diagram of a first fixing structure provided on a back plate of a display module proposed in an embodiment of the present application. Figure 6 As shown, since the first fixed structure 21 is a groove-shaped structure including the slide groove 212 and the first slideway 211, in order to prevent the first fixed structure arranged on the back panel 1 from causing adverse effects on the film layer function inside the back panel 1, the back panel 1 is provided with a fixed structure cover plate 11 protruding relative to the light-emitting side surface of the back panel 1, and the fixed structure cover plate 11 cooperates with the back panel 1 to form a receiving space, and the first fixed structure 21 is arranged on a plane opposite to the fixed structure cover plate 11 and the light-emitting side surface of the back panel 1. Optionally, the thickness of the fixed structure cover plate 11 is greater than or equal to 0.3 mm and less than or equal to 1 mm. Exemplarily, the thickness of the fixed structure cover plate 11 is 0.5 mm.

Figure 8 As shown, the second fixing structure includes a second slide 221, and the second slide 221 protrudes from one side edge of the back plate 1 away from the back plate 1 in a direction away from the back plate 1 to form the plurality of fixing grooves 222. Optionally, since the width of the circuit board 2 is relatively small (approximately between 8 mm and 12 mm), in order to further expand the distance range between different fixing grooves 222 and the back plate 1, the second slide 221 is an arcuate slide protruding in a direction away from the back plate 1; the plurality of fixing grooves 222 are arranged at intervals along a third direction, and the third direction is the extension direction of the arcuate edge of the second slide 221 away from one side of the back plate 1.

[0066] In some optional embodiments, Fig. 9 FIG. 4 shows a top view of a first fixing groove and a second fixing groove in a second fixing structure proposed in an embodiment of the present application.

In the embodiment of the present application, by setting fixing grooves 222 with different spacings, it is ensured that the plurality of fixing grooves 222 include at least two fixing grooves 222 with different distances from the back plate 1 along the first direction, so that a display module including a plurality of back plates 1 and the circuit board 2 with different distances can be formed based on the first fixing grooves 41 and the second fixing grooves 42.

[0067] It is easy to understand that the plurality of fixing grooves 222 may further include a plurality of adjacent third fixing grooves, and the spacing between the centers of the adjacent third fixing grooves along the first direction is different from both the first spacing and the second spacing.

[0071] Figure 4 FIG. 2 shows a second side view schematic diagram of a connection structure between a circuit board and a back plate in a display module proposed in an embodiment of the present application. Figure 4 As shown, the first protrusion 511 has substantially the same shape and size as the end of the slide groove 212, and the first protrusion 511 is interference fit with any one of the slide grooves 212; the limit block 512 is arranged inside the accommodating space to prevent the first protrusion 511 fixed to the slide groove 212 from sliding.
