DETAILED DESCRIPTION

[0041] 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.

[0042] In the related art, the back panel of the MLED display module generally includes four sides, among which on one side of the flexible circuit board corresponding to the light-emitting lamp board (hereinafter referred to as the connection side of the back panel), since the flexible circuit board needs to be bent to the other side of the back panel, multiple openings are provided on this side of the back panel for the flexible circuit board to pass through, and the openings are formed by multiple retaining walls on the connection side of the back panel. At the same time, when the inner rubber frame is connected to the back panel, the other sides of the back panel and the inner rubber frame are generally fixed to the back panel by gluing or buckling points. However, due to the presence of multiple openings on the connection side of the back panel, if gluing is used, it will make the display module difficult to repair and disassemble and complicated to assemble. Therefore, the structure of the inner rubber frame or the back panel needs to be changed on this side to ensure the support strength of the inner rubber frame.

[0043] Currently, there are generally two ways to achieve the connection between the inner rubber frame and the connecting side of the back plate.

[0044] One method is to stretch the inner rubber frame toward the back panel to make the inner rubber frame contact with the bottom surface of the back panel, thereby supporting the inner rubber frame and positioning the inner rubber frame perpendicular to the back panel. Therefore, sufficient clearance needs to be reserved between the retaining wall on the connection side of the back panel and the light board. This causes a certain increase in the distance between the light board and the connection side of the back panel, thereby increasing the final border distance of the display module. In addition, the extended part of the inner rubber frame is at risk of crushing the edge of the light board.

[0045] The other method is to lengthen or adjust the structure of the metal covering layer to fix the inner rubber frame on the connecting side. The metal covering layer needs to extend toward the inner side of the back panel to support the inner rubber frame, and the supporting surface needs to be wide enough to support and fix the inner rubber frame. At the same time, the metal covering layer needs to be assembled before the inner rubber frame is assembled, which will increase the production cycle of the display module and make the display module difficult to repair.

[0046] In view of this, the embodiment of the present application proposes a display module and a display device, by setting a back plate and an inner rubber frame, a plurality of retaining walls are set on the connection side of the back plate, and a plurality of connecting parts are set on the side of the inner rubber frame corresponding to the connection side, wherein at least one of the plurality of retaining walls is set as a deformable retaining wall, and a clamping piece is set on the connecting part corresponding to the deformable retaining wall. When the inner rubber frame is connected to the back plate, the deformed part on the deformable retaining wall is embedded in the clamping piece on the corresponding connecting part; in this way, the inner rubber frame and the back plate can be fixed, and the cooperation between the deformable retaining wall and the clamping piece can ensure the supporting strength of the inner rubber frame, and will not cause the risk of damage to other structures in the display module, thereby improving the yield of the display module. At the same time, the display module can be used to realize the narrow frame design on the connection side of the back plate, thereby providing a guarantee for the subsequent borderless design of the display module.

[0047] Reference Figure 1As shown, a display module disclosed in an embodiment of the present application includes a back plate 10 and a light-emitting lamp board 40 , an inner plastic frame 30 , an outer plastic frame 50 and a panel 60 arranged on the back plate 10 .

[0048] Specifically, the back plate 10 is generally made of metal material, such as aluminum alloy, etc. The back plate 10 includes a connection side, which corresponds to the side where the flexible circuit board 401 on the light emitting board 40 is located, that is, after the light emitting board 40 is fixed on the back plate 10, the flexible circuit board 401 on the light emitting board 40 is located at the position where the connection side of the back plate 10 is located.

[0049] The connection side of the back plate 10 is formed with a plurality of openings, and the formation of these openings also forms a plurality of retaining walls 20 on the connection side of the back plate 10. It is understandable that the plurality of retaining walls 20 are evenly spaced along the length direction of the connection side, and a opening can be formed between two adjacent retaining walls 20, and the flexible circuit board 401 is located in these openings. There are a plurality of flexible circuit boards 401 of the light emitting lamp panel 40, and each flexible circuit board 401 is located in a separate opening.

[0050] Reference Figure 1 and Figure 4 As shown, the light board 40 is arranged on the back plate 10 and is located on one side of the back plate 10. The light board 40 mainly plays the role of emitting light in the display module. In the embodiment of the present application, the display module is an MLED display module, so the light board 40 can include a plurality of micro light emitting diodes, and at the same time, driving lines of these micro light emitting diodes are formed on the light board 40. The driving lines finally converge on the same side of the light board 40 and are connected to the flexible circuit board 401 of the light board 40, and then connected to the driving board of the display module through the flexible circuit board 401. The driving board can make these micro light emitting diodes emit light.

[0051] Furthermore, the inner plastic frame 30 is disposed on the back plate 10 , and the inner plastic frame 30 is located on a side of the light emitting lamp panel 40 away from the back plate 10 .

[0052] Specifically, the inner plastic frame 30 is divided into four sections, wherein the three sections of the inner plastic frame 30 are separately assembled with the other three non-connected sides of the back plate 10 by gluing or buckling, and the inner plastic frame 30 is provided with a plurality of connecting parts 301 on one side corresponding to the connecting side of the back plate 10, the number of the connecting parts 301 is the same as the number of the retaining walls 20 on the connecting side of the back plate 10, and the positions of the connecting parts 301 correspond to the positions of the retaining walls 20 one by one. In the embodiment of the present application, the connecting part 301 is a plate body with a length slightly greater than the length of the retaining wall 20, and after the inner plastic frame 30 is connected to the back plate 10, the connecting part 301 will fit on the inner side of the corresponding retaining wall 20.

[0053] In the embodiment of the present application, at least one retaining wall 20 among the multiple retaining walls 20 is configured as a deformable retaining wall 202. It can be understood that the structure of the deformable retaining wall 202 is different from the structures of the other retaining walls 20, and the deformable retaining wall 202 is a retaining wall 20 that has undergone structural changes in order to be connected to the inner rubber frame 30. The function of the deformable retaining wall 202 itself is the same as that of other non-deformable retaining walls 201.

[0054] At the same time, refer to Figure 1 , Figure 2 and Figure 3 As shown, a clamping member 302 is provided on the connection portion 301 corresponding to the deformable retaining wall 202. The clamping member 302 includes a first plate 3021 and a second plate 3022, wherein the first plate 3021 is parallel to the back plate 10, one side of the first plate 3021 is connected to the connection portion 301, and the other side is connected to the second plate 3022, and the first plate 3021 and the second plate 3022 are perpendicular to each other, and at the same time, a clamping area is formed between the connection portion 301, the first plate 3021 and the second plate 3022. The size of the snap-fitting area in the first direction is matched with the size of the deformable retaining wall 202 in the first direction, so that the deformable retaining wall 202 can be just inserted into the snap-fitting area and will not increase the distance between the inner rubber frame 30 and the retaining wall 20, wherein the first direction is a direction perpendicular to the wall surface of the retaining wall 20, so the size of the deformable retaining wall 202 in the first direction can be understood as the thickness of the deformable retaining wall 202; in this way, the frame distance of the display module on the connection side can be reduced, thereby realizing the narrow frame design of the display module.

[0055] When the inner plastic frame 30 is connected to the back plate 10, the deformed portion A on the deformable retaining wall 202 will be embedded in the engaging area formed by the engaging member 302 on the corresponding connecting portion 301. In addition, in the embodiment of the present application, after the engaging member 302 is engaged with the deformed portion A of the deformable retaining wall 202, the deformable retaining wall 202 and the corresponding connecting portion 301 are in a relatively fixed state, and since the back plate 10 and the deformable retaining wall 202 are in a fixed state, the positioning and fixing of the inner plastic frame 30 can be achieved in this way.

[0056] Through the above-mentioned display module provided by the embodiment of the present application, the connection between the deformable retaining wall 202 and the corresponding locking piece 302 on the connecting part 301 can be used to achieve a stable connection between the inner rubber frame 30 and the connecting side of the back plate 10, and because the inner rubber frame 30 is directly connected to the retaining wall 20 on the connecting side of the back plate 10, the force acting on this side of the inner rubber frame 30 will be transmitted to the retaining wall 20 on the connecting side of the back plate 10. Therefore, this structure can ensure the supporting strength of the inner rubber frame 30 without causing damage to other structures of the display module and adding no other production processes, so that the yield and production cycle of the display module will not be affected. At the same time, because the inner rubber frame is directly connected through the deformable retaining wall without any other connecting structure in the middle, the display module can be used to achieve a narrow frame design on the connecting side of the back plate, thereby providing a guarantee for the subsequent frameless design of the display module.

[0057] Furthermore, the outer plastic frame 50 in the display module is arranged on the outside of the back plate 10, and the outer plastic frame 50 is fixedly connected to the non-connected side of the back plate 10 by snapping points, and on the connected side, the outer plastic frame 50 is connected to the plurality of retaining walls 20. The panel 60 in the display module is arranged on the outer plastic frame 50, and the panel 60 is connected to the outer plastic frame 50 by a plastic material. At the same time, in the display module, a diffusion plate and a diaphragm are also arranged on the side of the inner plastic frame 30 away from the back plate 10, and the diffusion plate and the diaphragm are located between the panel 60 and the light-emitting lamp board 40.

[0058] In an optional embodiment, referring to Figure 2 As shown, an embodiment of the present application further provides a display module, in which a deformable retaining wall 202 includes a non-deformed portion B and two deformed portions A, wherein the two deformed portions A are located at both ends of the length direction of the non-deformed portion B, wherein the length direction of the non-deformed portion B is also the length direction of the connecting side.

[0059] The difference between the non-deformed portion B and the deformed portion A is that the sizes of the two in the second direction are different. In this embodiment, the size of the deformed portion A in the second direction is smaller than the size of the non-deformed portion B in the second direction, that is, the height of the deformed portion A is lower than the height of the non-deformed portion B, which makes the overall shape of the deformable retaining wall 202 roughly a "convex" shape. The convex part of the "convex"-shaped deformable retaining wall 202 is the non-deformed portion B, and the part that is retracted relative to the non-deformed portion B is the deformed portion A. Among them, the second direction is a direction perpendicular to the back plate 10, the size of the deformed portion A in the second direction can be understood as the height of the deformed portion A, and the size of the non-deformed portion B in the second direction can be understood as the height of the non-deformed portion B.

[0060] At the same time, refer to Figure 2 and Figure 3As shown, in this embodiment, two engaging members 302 are arranged on the connection part 301 corresponding to the deformable retaining wall 202, and the two engaging members 302 correspond to the two deformed parts A respectively. Each engaging member 302 further includes a third plate 3023, and the third plate 3023 is located on the same side of the first plate 3021 and the second plate 3022, and the third plate 3023 is connected to the first plate 3021 and the second plate 3022 at the same time, and the third plate 3023 closes one side of the engaging area. It can be understood that in this embodiment, the third plates 3023 of the two engaging members 302 are arranged relative to each other, so that the two engaging members 302 can completely wrap up the two deformed parts A respectively, so that the engaging members can be better connected to the deformable retaining wall 202.

[0061] Reference Figure 4 and Figure 5 As shown, after the deformable retaining wall 202 is engaged with the engaging member 302 on the connecting portion 301, firstly, since the engaging member 302 is not through in the second direction, the engaging member 302 will limit the displacement of the deformable retaining wall 202 in the second direction. Secondly, after the two engaging members 302 are engaged with the deformed portions A on both sides, the two engaging members 302 will wrap up the deformed portions A of the deformable retaining wall 202, so that the deformable retaining wall 202 and the connecting portion 301 can be relatively fixed. In this way, the positioning of the inner rubber frame 30 in all directions can be relatively achieved, thereby achieving the fixation of the inner rubber frame 30. From another perspective, it can also be understood that the connecting portion 301 of the inner rubber frame 30 is hung on the deformable retaining wall 202 through the engaging member 302, thereby achieving the connection between the inner rubber frame 30 and the back plate 10.

[0062] Meanwhile, in this embodiment, the non-deformed portion B of the deformable retaining wall 202 may be connected to the outer plastic frame 50 .

[0063] In addition, refer to Figure 5 As shown, in this embodiment, the inner plastic frame 30 is not connected to the light board 40 at the connection side of the back plate 10, that is, a gap is formed between the inner plastic frame 30 and the light board 40, so the inner plastic frame 30 will not cause the risk of squeezing and damaging the edge of the light board 40. In addition, there is no need to set up other structures to support the inner plastic frame 30, and the manufacturing process of the entire display module will not increase, thereby ensuring the manufacturing efficiency of the display module.

[0064] In practical applications, the deformable retaining wall 202 itself may be incomplete at the corner position of the connection side of the back plate 10 (that is, the position where the connection side is connected to the non-connection side). For example, at the corner position of the connection side, the deformable retaining wall 202 may include only half of the structure (which can be understood as the other half of the deformable retaining wall 202 is cut off), and the connection portion 301 corresponding to the position on the inner rubber frame 30 is also adaptively changed.

[0065] The inner plastic frame 30 and the deformable retaining wall 202 structure in the above-mentioned display module can be applied to most MLED display modules. However, when the number of flexible circuit boards 401 of the light-emitting lamp panel 40 is large, the length of each retaining wall 20 on the connection side of the back panel 10 will also become smaller. At this time, if the retaining wall 20 is made into a "convex" shaped deformable retaining wall 202, it may affect the connection effect between the deformable retaining wall 202 and the outer plastic frame 50 (it can be understood that when the length of the entire deformable retaining wall 202 becomes smaller, the length of the non-deformed part B in the "convex" shaped deformable retaining wall 202 will also become smaller).

[0066] To deal with the above situation, refer to Figure 6 As shown, in an optional embodiment, the embodiment of the present application also provides a display module, in which the multiple retaining walls 20 include a plurality of deformable retaining walls 202 and a plurality of non-deformable retaining walls 201, and the deformable retaining walls 202 and the non-deformable retaining walls 201 are alternately distributed along the length direction of the connecting side of the back panel 10.

[0067] Specifically, in this embodiment, the non-deformable retaining wall 201 is a retaining wall 20 that has not undergone any structural changes, and the number of the non-deformable retaining walls 201 may be different from the number of the deformable retaining walls 202, that is, the alternating distribution of the deformable retaining walls 202 and the non-deformable retaining walls 201 may not be continuous. For example, one deformable retaining wall 202 and one non-deformable retaining wall 201 may be alternately distributed on the connection side of the back plate 10, or one deformable retaining wall 202 and two non-deformable retaining walls 201 may be alternately distributed on the connection side of the back plate 10, and those skilled in the art may make settings according to actual needs.

[0068] In actual applications, this arrangement is not fixed, that is, the position of the deformable retaining wall 202 can be set in an irregular arrangement, and the number of the deformable retaining wall 202 can be designed according to the size of the back plate 10. Generally speaking, the longer the length of the connecting side of the back plate 10, the more deformable retaining walls 202 are required. In the embodiment of the present application, at least three deformable retaining walls 202 are provided.

[0069] Further, refer to Figure 7 As shown, in this embodiment, a deformation portion A is provided on the deformable retaining wall 202 , and the deformation portion A is provided along the length direction of the deformable retaining wall 202 .

[0070] Specifically, the length direction of the deformable retaining wall 202 is also the length direction of the connecting side of the back plate 10, and the deformed portion A is arranged along the length direction of the deformable retaining wall 202, that is, the deformable retaining wall 202 is changed in overall structure compared with the non-deformable retaining wall 201.

[0071] Reference Figure 7 As shown, in this embodiment, the deformable retaining wall 202 is mainly changed in height compared with the non-deformable retaining wall 201. The dimension of the deformable retaining wall 202 in the second direction is smaller than the dimension of the non-deformable retaining wall 201 in the second direction, that is, the height of the deformable retaining wall 202 is lower than that of the non-deformable retaining wall 201, so that the retaining walls 20 with different heights and staggered distribution can be formed on the connection side of the back plate 10.

[0072] Further, refer to Figure 7 and Figure 8 As shown, in this embodiment, a clamping member 302 matching the length of the deformed portion A is provided on the connecting portion 301 corresponding to the deformable retaining wall 202. The clamping member 302 also includes a fourth plate 3024 and a fifth plate 3025, which are respectively located on both sides of the first plate 3021, and the fourth plate 3024 closes one side of the clamping area, and the fifth plate 3025 closes the other side of the clamping area. Therefore, in this embodiment, except for the opening, the other sides of the clamping member 302 are all closed, that is, after the clamping member 302 is clamped with the deformable retaining wall 202, the clamping member 302 will completely wrap up a part of the deformable retaining wall 202.

[0073] Reference Fig. 9 As shown, a limiting portion 305 is provided on the connection portion 301 corresponding to the non-deformable retaining wall 201. After the non-deformable retaining wall 201 is connected with the limiting portion 305, the limiting portions 305 are respectively located at both ends of the length direction of the non-deformable retaining wall 201.

[0074] Through the above-mentioned display module provided in the embodiment of the present application, the connection between the inner plastic frame 30 and the back plate 10 can be achieved by connecting the deformable retaining wall 202 with the corresponding locking part 302 on the connecting part 301, while the non-deformable retaining wall 201 can achieve the connection and fixation between the outer plastic frame 50 and the back plate 10, so that the connection structure of the display module is more stable.

[0075] In an optional embodiment, referring to Figure 4 and Figure 5 As shown, the embodiment of the present application further provides a display module, in which an extension portion 303 is provided at a position of the inner plastic frame 30 corresponding to the connection portion 301 , and a reinforcing rib 304 is provided between the extension portion 303 and the connection portion 301 .
