[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Currently, display devices are characterized by a wide variety of innovative products, short development cycles, and customer-specified appearance and dimensions. For certain display devices, customers typically offer two shipping options: flat display modules and bent display modules of the same size and model.

[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 requires the mold to be remade and the appearance size to be updated in order to cope with product iteration updates, resulting in a waste of resources.

[0053] In view of this, embodiments of this application propose a display module, Figure 1 This application provides a schematic diagram illustrating the structure of a circuit board and backplate in a display module according to an embodiment of the present application. Figure 1 As shown, the display module includes: a back plate 1, and a circuit board 2 disposed on one side of the back plate 1. The orthographic projections of the back plate 1 and the circuit board 2 on a plane parallel to the back plate 1 do not overlap, and the back plate 1 and the circuit board 2 form a flat display module. A gap exists between the back plate 1 and the circuit board 2.

[0054] In the embodiments of this application, Figure 2This illustration shows a top view of the connection structure between the circuit board and the backplate in a display module according to an embodiment of this application. Figure 3 This illustration shows one of the side view schematic diagrams of the connection structure between the circuit board and the back plate in a display module according to an embodiment of this application, such as... Figure 2 and Figure 3 As shown, the back plate 1 is provided with at least one first fixing structure 21, the first fixing structure 21 includes a plurality of sliding grooves 212, the plurality of sliding grooves 212 are arranged at intervals along a first direction, the first direction being the arrangement direction of the orthographic projection of the back plate 1 and the circuit board 2 on the plane where the back plate 1 is located; the circuit board 2 is provided with at least one second fixing structure 22, the second fixing structure 22 includes a plurality of fixing slots 222 arranged at intervals, and in the first direction, at least two fixing slots 222 are at different distances from the back plate 1.

[0055] In this embodiment of the application, the first fixing structure 21 on the back plate 1 is connected to the circuit board 2 through the sliding groove 212, and the second fixing structure 22 on the circuit board 2 is connected to the back plate 1 through the fixing groove 222. In this embodiment, because the multiple grooves 212 on the first fixing structure 21 are arranged at intervals along the first direction, the distances from different grooves 212 to the circuit board 2 along the first direction are different. In the first direction, at least two fixing slots 222 on the circuit board 2 are at different distances to the back plate 1. Therefore, when different grooves 212 and different fixing slots 222 form a fixed connection, the distances between the back plate 1 and the circuit board 2 along the first direction are different. Thus, when connecting the back plate 1 and the circuit board 2 based on the first fixing structure 21 and the second fixing structure 22, the distances between different back plates 1 and the circuit board 2 can be determined according to product requirements or models. This effectively avoids the need to redesign the connection structure between the back plate 1 and the circuit board 2 due to different product models. Through the first fixing structure 21 and the second fixing structure 22 provided in this application embodiment, the compatible design of different display modules can be realized, which greatly simplifies the product process, saves human and material resources, and reduces production costs.

[0056] In this embodiment, the display module further includes a connector 23, through which the backplate 1 and the circuit board 2 are fixedly connected. Specifically, Figure 11 This application provides a schematic diagram of the structure of a connector in a display module according to an embodiment of the present application. Figure 11As shown, the connector 23 is provided with a first fixing part 51 and a second fixing part 52. The first fixing part 51 is fixedly connected to any one of the sliding grooves 212 of the first fixing structure 21, and the second fixing part 52 is fixedly connected to any one of the fixing grooves 222 of the second fixing structure 22. Since the distances from different sliding grooves 212 to the circuit board 2 are different, the connector 23 is fixedly connected to different sliding grooves 212 and different fixing grooves 222 respectively, so that different distances are formed between the backplate 1 and the circuit board 2 after connection, in order to match different product models or customer needs.

[0057] In some alternative implementations, Figure 5 This invention provides a top view of a first fixing structure disposed on the 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 rail 211 extending along the first direction. The first slide rail 211 is configured to provide a path for the first fixing part 51 to move from one slide groove 212 to another. The edge of the first slide rail 211 extending along the first direction protrudes along a second direction to form the plurality of slide grooves 212. The second direction is a direction perpendicular to the first direction on the plane of the back plate 1. Optionally, each slide groove 212 further includes an engraved line extending along the second direction. The engraved line is used to locate the position of each slide groove 212, facilitating better confirmation of the slide groove 212 connected to the connector 23 and improving the user experience.

[0058] In some alternative embodiments, in order to increase the distance range between the slide groove 212 on the back plate 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 disposed opposite to each other, and the plurality of slide grooves 212 include a first slide groove 31 formed by the first edge protruding along the second direction, and a second slide groove 32 formed by the second edge protruding along the second direction, wherein the first slide groove 31 and the second slide groove 32 extend in opposite directions in the second direction.

[0059] In some alternative embodiments, the first slide groove 31 and the second slide groove 32 are arranged alternately along the first direction. Optionally, in each of the first fixing structures, the number of the first slide groove 31 and the second slide groove 32 are the same.

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

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

[0062] For example, each of the first fixing 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 arranged alternately along the first direction, and the center distance between adjacent slide grooves 212 along the first direction (i.e. the distance between the engraving lines corresponding to adjacent slide grooves 212 along the first direction) is 0.5 mm.

[0063] In some alternative implementations, Figure 6 This illustration shows a side view of a first fixing structure disposed on the back plate of a display module according to an embodiment of this application. Figure 6 As shown, since the first fixing structure 21 is a groove-shaped structure including the slide groove 212 and the first slide rail 211, in order to prevent the first fixing structure provided on the back plate 1 from adversely affecting the function of the film layer inside the back plate 1, the back plate 1 is provided with a fixing structure cover plate 11 protruding relative to the light-emitting side surface of the back plate 1. The fixing structure cover plate 11 cooperates with the back plate 1 to form an accommodating space, and the first fixing structure 21 is provided on the plane opposite to the light-emitting side surface of the back plate 1. Optionally, the thickness of the fixing structure cover plate 11 is greater than or equal to 0.3 mm and less than or equal to 1 mm. For example, the thickness of the fixing structure cover plate 11 is 0.5 mm.

[0064] In some alternative implementations, Figure 7 This illustration shows a schematic diagram of the positional distribution of the first fixing structure on the backplate of a display module according to an embodiment of this application, as follows: Figure 7As shown, in order to ensure the stability of the connection between the back plate 1 and the circuit board 2, there are multiple first fixing structures 21. The multiple first fixing structures 21 are disposed on the inner side of the back plate 1 near the edge of the circuit board 2. The multiple first fixing structures 21 are symmetrically arranged about the back plate 1 along the first direction axis. The number of second fixing structures 22 is the same as that of the first fixing structures 21. On a plane parallel to the back plate 1, the first fixing structures 21 and the second fixing structures 22 are respectively aligned along the first direction.

[0065] In some alternative implementations, Figure 8 This application provides a top view schematic diagram of a second fixing structure disposed on a circuit board in a display module according to an embodiment of the present application. Figure 8 As shown, the second fixing structure includes a second slide rail 221, the edge of the second slide rail 221 away from the back plate 1 protruding 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 8mm-12mm), in order to further expand the distance range between the different fixing grooves 222 and the back plate 1, the second slide rail 221 is an arc-shaped slide rail protruding in a direction away from the back plate 1; the plurality of fixing grooves 222 are arranged at intervals along a third direction, the third direction being the extension direction of the arc-shaped edge of the second slide rail 221 away from the back plate 1.

[0066] In some alternative implementations, Figure 9 This paper shows a top view of the first and second fixing grooves in a second fixing structure according to an embodiment of the present application, as shown in the figure. Figure 9 As shown, the plurality of fixing slots 222 include a plurality of adjacent first fixing slots 41 and a plurality of adjacent second fixing slots 42. The distance between the centers of adjacent first fixing slots 41 along the first direction is a first distance d1, and the distance between the centers of adjacent second fixing slots 42 along the first direction is a second distance d2. The first distance d1 is greater than the second distance d2. In this embodiment, by setting fixing slots 222 with different distances, it is ensured that the plurality of fixing slots 222 include at least two fixing slots 222 that are at different distances from the back plate 1 along the first direction. Thus, a display module containing a plurality of back plates 1 and circuit boards 2 with different distances can be formed based on the first fixing slots 41 and the second fixing slots 42.

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

[0068] For example, such as Figure 9As shown, each of the second fixing structures 22 includes an arc-shaped second slide rail 221 and a plurality of fixing grooves 222. The fixing grooves 222 are circular fixing grooves, and the shape and size of the fixing grooves 222 are the same as those of the second fixing parts 52 on the connector 23. The fixing grooves 222 include five adjacent first fixing grooves 41 and five adjacent second fixing grooves 42. The first distance between adjacent first fixing grooves 41 is 1 mm, and the first distance between adjacent second fixing grooves 42 is 0.5 mm.

[0069] also, Figure 10 This illustration shows a schematic diagram of the positional distribution of a second fixing structure on a circuit board in a display module according to an embodiment of this application. Figure 10 As shown in this embodiment, to ensure the stability of the connection between the backplate 1 and the circuit board 2, multiple second fixing structures 22 are provided, and these multiple second fixing structures 22 are symmetrically arranged about the circuit board 1 along the axis of the first direction. The circuit board 2 has at least one connection area, and the second fixing structure 22 is disposed within the connection area, where wiring can proceed normally. To prevent the second fixing structure 22 from adversely affecting the components on the circuit board 2, the components on the circuit board 2 are disposed outside the connection area.

[0070] In some alternative implementations, Figure 11 This application provides a schematic diagram of the structure of a connector in a display module according to an embodiment of the present application. Figure 11 As shown, the connector 23 further includes a connecting plate 53, and the first fixing part 51 and the second fixing part 52 are disposed at opposite ends of the connecting plate 53; the first fixing part 51 includes a first protrusion 511 and a limiting block 512, the limiting block 512 is disposed on the side of the first protrusion 511 away from the connecting plate 53, and is fixedly connected to the first protrusion 511.

[0071] Figure 4 This is a second side view schematic diagram of the connection structure between the circuit board and the back plate in a display module according to an embodiment of this application, as shown below. Figure 4 As shown, the first protrusion 511 and the slide groove 212 have approximately the same end shape and size. The first protrusion 511 is interference-fitted with any one of the slide grooves 212. The limiting block 512 is disposed inside the receiving space to prevent the first protrusion 511, which is fixed to the slide groove 212, from sliding.

[0072] In some optional embodiments, the second fixing part 52 is a through hole penetrating the connecting plate 53. The shape and size of the through hole are approximately the same as those of the fixing groove. The second fixing part 52 and any fixing groove 222 are fixedly connected by fasteners penetrating the second fixing part 52 and the fixing groove 222. For example, the second fixing part 52 is a threaded hole with a diameter of 1.4 mm, and the fixing groove 222 has a diameter of 1.5 mm. Threaded fasteners penetrating the second fixing part 52 and the fixing groove 222 are used to achieve a fixed connection between the connector 23 and the circuit board 2.

[0073] In some alternative embodiments, the second fixing part may also be a second protrusion, the second protrusion having a shape and size substantially the same as the fixing groove, and the second protrusion being interference-fitted with any one of the fixing grooves.

[0074] Figure 12 This illustration shows a schematic diagram of the boundary region between the circuit board and the backplane in a display module according to an embodiment of this application. Figure 12 As shown in the embodiment of this application, by setting a first fixing structure 21 having a plurality of sliding grooves 212 spaced apart along the first direction and a second fixing structure 22 having at least two fixing grooves 222 at different distances from the back plate 1, the distance A between the edge of the back plate 1 near the circuit board 2 and the edge of the circuit board 2 near the back plate 1 is greater than or equal to 0.5 mm and less than or equal to 4 mm; the distance B between the opposite sides of the circuit board 2 along the first direction is greater than or equal to 8 mm and less than or equal to 12 mm, thereby making the range of distances between the back plate 1 and the circuit board 2 that the display module is compatible with greater than or equal to 5.2 mm and less than or equal to 16 mm.

[0075] In some optional implementations, in some display modules, the circuit board 2 and the back plate 1 have a step difference in a direction perpendicular to the plane of the back plate. To ensure that the back plate 1 and the circuit board 2 with this step difference can be compatible with various distances, Figure 13 This illustration shows a schematic diagram of the structure of a first connecting plate and a second connecting plate in a display module according to an embodiment of this application during the sliding process. Figure 13As shown in the embodiment of this application, the connector 23 includes a first connecting plate 61 and a second connecting plate 62. The first connecting plate 61 includes a first surface 611 and a second surface 612 that are perpendicular to each other. The first surface 611 is provided with a second fixing part 52. The second connecting plate is perpendicular to the second surface 612. The second surface 612 is provided with a third fixing structure 71. The third fixing structure 71 includes a third slide rail 711 extending along a fourth direction and at least one slot 712 perpendicular to the third slide rail 711. The fourth direction is the direction perpendicular to the plane where the back plate 1 is located.

[0076] The second connecting plate 62 includes a first surface 621 and a first side surface 622 adjacent to the first surface 621. The first surface 621 is provided with the first fixing part 51. The first side surface 622 is provided with a third fixing part 81. The third fixing part 81 includes a locking block 811 and a sliding shaft 812 connecting the locking block 811 and the first side surface 622. The sliding shaft 812 is configured to drive the second connecting plate 62 to slide and / or rotate within the third slide rail 711. The locking block 811 is configured to be interference-fitted with any one of the slots 712 when the second connecting plate 62 is rotated to be parallel to the first surface 611 of the first connecting plate 61.

[0077] like Figure 13 As shown, before the fixed connection, the second connecting plate 62 is perpendicular to the first surface 611 of the first connecting plate 61. The sliding shaft 812 slides within the third slide rail 711 along the fourth direction, causing the second connecting plate 62 to slide along the fourth direction. The second connecting plate 62 is fixedly connected to different slots 712, achieving a design that allows the circuit board 2 and the back plate 1 to be compatible with different distances in the fourth direction.
