DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] In the related art, the backboard of the MLED display module generally includes four sides. On the side of the backboard corresponding to the flexible circuit board of the light-emitting lamp panel (hereinafter referred to as the connecting side of the backboard), a plurality of breakages are provided on the side of the backboard for the flexible circuit board to pass through, and the breakages are formed by a plurality of retaining walls on the connecting side of the backboard. When the inner frame is connected to the backboard, the other sides of the backboard are generally fixed to the backboard by means of adhesion or buckling points. However, due to the plurality of breakages on the connecting side of the backboard, if the adhesion method is used, it will be difficult to disassemble and assemble the display module, and thus the structure of the inner frame or the backboard on the connecting side needs to be changed to ensure the support strength of the inner frame.

[0043] Currently, there are two ways to connect the inner frame to the connecting side of the backboard.

[0044] One way is to stretch the inner frame towards the backboard to make the inner frame contact the bottom surface of the backboard, thereby achieving the support of the inner frame and the positioning of the inner frame perpendicular to the backboard. Therefore, a sufficient gap needs to be reserved between the retaining walls on the connecting side of the backboard and the light-emitting lamp panel, which increases the distance between the light-emitting lamp panel and the connecting side of the backboard, resulting in an increase in the final frame distance of the display module. In addition, the extended part of the inner frame has a risk of crushing the edge of the light-emitting lamp panel.

[0045] The other way is to lengthen or adjust the structure of the metal cover layer to fix the inner frame on the connecting side. The metal cover layer needs to extend towards the inner side of the backboard to bear the inner frame, and the bearing surface needs to have sufficient width to achieve the bearing and fixing of the inner frame. In addition, the assembly of the metal cover layer needs to be completed before the assembly of the inner frame, which increases the production cycle of the display module and makes the display module difficult to maintain.

[0046] Therefore, embodiments of the present application provide a display module and a display device. The display module includes a backboard and an inner frame. The connecting side of the backboard is provided with a plurality of retaining walls, and the side of the inner frame corresponding to the connecting side is provided with a plurality of connecting parts. At least one of the plurality of retaining walls is a deformed retaining wall, and the connecting part corresponding to the deformed retaining wall is provided with a clamping piece. When the inner frame is connected to the backboard, the deformed part of the deformed retaining wall is embedded into the clamping piece on the corresponding connecting part. In this way, the inner frame and the backboard can be fixed, and the support strength of the inner frame can be ensured by the cooperation of the deformed retaining wall and the clamping piece, without causing damage to other structures in the display module. The yield of the display module is improved, and the narrow frame design of the connecting side of the backboard is achieved, which provides a guarantee for the bezel-less design of the subsequent display module.

[0047] Reference Figure 1As shown, a display module disclosed in the embodiment of the present application, the display module comprises a back plate 10 and a light-emitting lamp plate 40, an inner rubber frame 30, an outer rubber 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 and the like. Among them, the back plate 10 comprises a connecting side, which corresponds to the side of the flexible circuit board 401 on the light-emitting lamp plate 40, that is, after the light-emitting lamp plate 40 is fixed on the back plate 10, the flexible circuit board 401 on the light-emitting lamp plate 40 is located at the position of the connecting side of the back plate 10.

[0049] The connecting side of the back plate 10 is formed with a plurality of broken openings, and the plurality of broken openings also forms a plurality of retaining walls 20 on the connecting side of the back plate 10. It can be understood that the plurality of retaining walls 20 are uniformly spaced along the length direction of the connecting side, and a broken opening can be formed between two adjacent retaining walls 20, and the flexible circuit board 401 is located in the broken opening. Among them, the flexible circuit board 401 of the light-emitting lamp plate 40 is provided with a plurality of flexible circuit boards 401, and each flexible circuit board 401 is located in a separate broken opening.

[0050] Referring to Figure 1 and Figure 4 As shown, the light-emitting lamp plate 40 is arranged on the back plate 10 and located at one side of the back plate 10, and the light-emitting lamp plate 40 mainly plays a 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-emitting lamp plate 40 can include a plurality of micro light-emitting diodes, and driving traces of the micro light-emitting diodes are formed on the light-emitting lamp plate 40. The driving traces finally converge to the same side of the light-emitting lamp plate 40 and are connected with the flexible circuit board 401 of the light-emitting lamp plate 40, and then connected with the driving board of the display module through the flexible circuit board 401. The driving board can make the micro light-emitting diodes emit light.

[0051] Further, the inner rubber frame 30 is arranged on the back plate 10, and the inner rubber frame 30 is located at the side of the light-emitting lamp plate 40 away from the back plate 10.

[0052] Specifically, the inner rubber frame 30 is divided into four sections, wherein three sections of the inner rubber frame 30 are separately assembled with the other three non-connecting sides of the back plate 10 by means of adhesion or fastening points, and the inner rubber frame 30 is provided with a plurality of connecting parts 301 at the 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 of the connecting side of the back plate 10, and the positions of the connecting parts 301 and the retaining walls 20 are one-to-one corresponding. In the embodiment of the present application, the connecting part 301 is a plate body with a length slightly larger than the length of the retaining wall 20, and after the inner rubber frame 30 is connected with the back plate 10, the connecting part 301 will be attached to the inner side of the corresponding retaining wall 20.

[0053] In the embodiments of the present application, at least one of the plurality of retaining walls 20 is provided as a deformed retaining wall 202. It can be understood that the structure of the deformed retaining wall 202 is different from that of the other retaining walls 20, and the deformed retaining wall 202 is a retaining wall 20 that is structurally changed for connection with the inner rubber frame 30. The deformed retaining wall 202 itself has the same function as the other non-deformed retaining walls 201.

[0054] At the same time, as shown in Figure 1 , Figure 2 and Figure 3 , a clamping piece 302 is arranged on the connecting portion 301 corresponding to the deformed retaining wall 202. The clamping piece 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 connecting 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. At the same time, the connecting portion 301, the first plate 3021 and the second plate 3022 form a clamping area. The size of the clamping area in the first direction is matched with the size of the deformed retaining wall 202 in the first direction, so that the deformed retaining wall 202 can be clamped into the clamping area, and the distance between the inner rubber frame 30 and the retaining wall 20 is not increased. The first direction is perpendicular to the wall surface of the retaining wall 20, so the size of the deformed retaining wall 202 in the first direction can be understood as the thickness of the deformed retaining wall 202. In this way, the frame distance of the display module on the connection side can be reduced, and the narrow frame design of the display module can be achieved.

[0055] When the inner rubber frame 30 is connected to the back plate 10, the deformed portion A on the deformed retaining wall 202 is embedded into the clamping area formed by the clamping piece 302 on the corresponding connecting portion 301. In the embodiments of the present application, after the clamping piece 302 and the deformed portion A of the deformed retaining wall 202 are fitted, the deformed retaining wall 202 and the corresponding connecting portion 301 are in a relatively fixed state. Since the back plate 10 and the deformed retaining wall 202 are in a fixed state, the positioning and fixing of the inner rubber frame 30 can be achieved.

[0056] By using the connection between the deformed retaining wall 202 and the clamping piece 302 on the corresponding connecting part 301, the display module provided by the embodiment of the present application can realize stable connection of the connecting side of the inner rubber frame 30 and the back plate 10. Since the inner rubber frame 30 is directly connected with the retaining wall 20 on the connecting side of the back plate 10, the force acting on the inner rubber frame 30 is transmitted to the retaining wall 20 on the connecting side of the back plate 10, so that the support strength of the inner rubber frame 30 can be ensured, and other structures of the display module are not damaged, and no other manufacturing processes are added, so that the yield and manufacturing period of the display module are not affected. Since the inner rubber frame is directly connected through the deformed retaining wall, no other connecting structure is arranged in the middle, so that the narrow frame design of the connecting side of the back plate can be realized by using the display module, and the bezel-free design of the subsequent display module is ensured.

[0057] Further, the outer rubber frame 50 in the display module is arranged on the outer side of the back plate 10, and the outer rubber frame 50 and the non-connecting side of the back plate 10 are fixedly connected through the buckling points, while on the connecting side, the outer rubber frame 50 is connected with the plurality of retaining walls 20. The panel 60 in the display module is arranged on the outer rubber frame 50, and the panel 60 and the outer rubber frame 50 are connected through the glue material. Meanwhile, in the display module, the diffuser plate and the film are arranged on the side of the inner rubber frame 30 away from the back plate 10, and the diffuser plate and the film are located between the panel 60 and the light-emitting lamp plate 40.

[0058] In an alternative embodiment, as shown in Figure 2 , the embodiment of the present application also provides a display module, in which the deformed retaining wall 202 includes a non-deformed part B and two deformed parts A, wherein the two deformed parts A are located at both ends of the length direction of the non-deformed part B, and the length direction of the non-deformed part B is the length direction of the connecting side.

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

[0060] Meanwhile, referring to Figure 2 and Figure 3As shown, in this embodiment, two clamping members 302 are arranged on the connecting portion 301 corresponding to the deformation retaining wall 202, and the two clamping members 302 correspond to the two deformation portions A respectively. Each clamping member 302 further comprises a third plate 3023, which is located on the same side of the first plate 3021 and the second plate 3022, and the third plate 3023 is connected with the first plate 3021 and the second plate 3022 at the same time, and the third plate 3023 closes one side of the clamping area. It can be understood that in this embodiment, the third plates 3023 of the two clamping members 302 are oppositely arranged, so that the two clamping members 302 can completely wrap the two deformation portions A respectively, so that the clamping member can be better connected with the deformation retaining wall 202.

[0061] Referring to Figure 4 and Figure 5 As shown, after the deformation retaining wall 202 is clamped with the clamping members 302 on the connecting portion 301, firstly, since the clamping member 302 is not through in the second direction, the clamping member 302 will limit the displacement of the deformation retaining wall 202 in the second direction, and secondly, after the two clamping members 302 are clamped with the deformation portions A on both sides, the two clamping members 302 will wrap the deformation portions A of the deformation retaining wall 202, so that the deformation retaining wall 202 and the connecting portion 301 can be relatively fixed, so that the positioning of the inner rubber frame 30 in each direction can be relatively realized, thereby realizing the fixation of the inner rubber frame 30. From another angle, it can also be understood that the connecting portion 301 of the inner rubber frame 30 is hung on the deformation retaining wall 202 through the clamping member 302, thereby realizing the connection between the inner rubber frame 30 and the back plate 10.

[0062] Meanwhile, in this embodiment, the non-deformation portion B of the deformation retaining wall 202 can be connected with the outer rubber frame 50.

[0063] In addition, referring to Figure 5 As shown, in this embodiment, the inner rubber frame 30 has no connection relationship between the connecting side of the back plate 10 and the light-emitting lamp plate 40, that is, a gap is formed between the inner rubber frame 30 and the light-emitting lamp plate 40, so that the inner rubber frame 30 will not cause the risk of extrusion damage to the edge of the light-emitting lamp plate 40. And there is no need to set other structures to bear the inner rubber frame 30, the manufacturing process of the whole display module will not be increased, thereby ensuring the manufacturing efficiency of the display module.

[0064] In actual application, the deformation retaining wall 202 itself can be incomplete at the corner position of the connecting side of the back plate 10 (that is, the position where the connecting side and the non-connecting side are connected). Exemplarily, at the corner position of the connecting side, the deformation retaining wall 202 can only include half of the structure (it can be understood as cutting off the other half of the deformation retaining wall 202), and the connecting portion 301 corresponding to the position on the inner rubber frame 30 is also adaptively changed.

[0065] The inner frame 30 and the deformed retaining wall 202 in the 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 connecting side of the back plate 10 will also be small. At this time, if the retaining wall 20 is made into a deformed retaining wall 202 in the shape of a "b", the connection effect between the deformed retaining wall 202 and the outer frame 50 may be affected (it can be understood that when the length of the entire deformed retaining wall 202 is small, the length of the non-deformed part B in the deformed retaining wall 202 in the shape of a "b" will also be small).

[0066] In order to deal with the above situation, referring to FIG. 8, in an alternative embodiment, the embodiments of the present application also provide a display module, in which the plurality of retaining walls 20 include a plurality of deformed retaining walls 202 and a plurality of non-deformed retaining walls 201, and the deformed retaining walls 202 and the non-deformed retaining walls 201 are alternately distributed along the length direction of the connecting side of the back plate 10. Figure 6 Specifically, in this embodiment, the non-deformed retaining wall 201 is the retaining wall 20 without structural changes, and the number of non-deformed retaining walls 201 and the number of deformed retaining walls 202 can be different, that is, the alternating distribution of deformed retaining walls 202 and non-deformed retaining walls 201 can not be continuous. For example, one deformed retaining wall 202 and one non-deformed retaining wall 201 can be alternately distributed on the connecting side of the back plate 10, or one deformed retaining wall 202 and two non-deformed retaining walls 201 can be alternately distributed on the connecting side of the back plate 10. Those skilled in the art can set it according to actual needs.

[0067] In actual application, this arrangement is not fixed, that is, the position of the deformed retaining wall 202 can be set according to an irregular arrangement, and the number of deformed retaining walls 202 can be designed according to the size of the back plate 10. Generally, the longer the length of the connecting side of the back plate 10, the more deformed retaining walls 202 are needed. In the embodiments of the present application, the deformed retaining wall 202 is provided with at least three or more.

[0068] Further, referring to FIG. 8, in this embodiment, the deformed retaining wall 202 is provided with a deformed part A, and the deformed part A is arranged along the length direction of the deformed retaining wall 202.

[0069] Figure 7 Specifically, the length direction of the deformed retaining wall 202 is the length direction of the connecting side of the back plate 10, and the deformed part A is arranged along the length direction of the deformed retaining wall 202, that is, the deformed retaining wall 202 is changed in the overall structure compared with the non-deformed retaining wall 201.

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

[0071] Referring to Figure 7 In this embodiment, the deformed retaining wall 202 is mainly changed in height compared with the non-deformed retaining wall 201. The deformed retaining wall 202 has a smaller size in the second direction than the non-deformed retaining wall 201, that is, the height of the deformed retaining wall 202 is reduced compared with the non-deformed retaining wall 201, so that the retaining walls 20 with different heights and staggered distribution can be formed on the connecting side of the back plate 10.

[0072] Further, referring to Figure 7 and Figure 8 In this embodiment, the connecting part 301 corresponding to the deformed retaining wall 202 is provided with a clamping part 302 matching the length of the deformed part A. The clamping part 302 further 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, the clamping part 302 is closed on all sides except the opening, that is, after the clamping part 302 is clamped with the deformed retaining wall 202, the clamping part 302 will completely wrap a part of the deformed retaining wall 202.

[0073] Referring to Figure 9 The connecting part 301 corresponding to the non-deformed retaining wall 201 is provided with a limiting part 305, which is respectively located at both ends of the non-deformed retaining wall 201 in the length direction after the non-deformed retaining wall 201 is connected with the cooperating connecting part.

[0074] By using the connection between the deformed retaining wall 202 and the clamping part 302 on the corresponding connecting part 301, the connection and fixation between the inner rubber frame 30 and the back plate 10 can be realized, and the non-deformed retaining wall 201 can realize the connection and fixation between the outer rubber frame 50 and the back plate 10, so that the connection structure of the display module is more stable.

[0075] In an alternative embodiment, referring to Figure 4 and Figure 5 The display module provided by the embodiment of the present application further includes an extending part 303 provided on the position corresponding to the connecting part 301 of the inner rubber frame 30, and a reinforcing rib 304 provided between the extending part 303 and the connecting part 301.

[0076] Specifically, in the embodiments of the present application, the extension part 303 can include a first sub-extension part and a second sub-extension part, wherein the first sub-extension part is connected with the inner rubber frame 30, the first sub-extension part extends towards a direction away from the inner rubber frame 30, and the first sub-extension part is parallel to the plate surface of the back plate 10; the second sub-extension part is connected with a side of the first sub-extension part away from the inner rubber frame 30, and the second sub-extension part extends obliquely towards the position where the back plate 10 is located. The extension part 303 and the connecting part 301 can form a reinforcing rib 304 to improve the support strength of the inner rubber frame 30.

[0077] Based on the same inventive concept, the embodiments of the present application also disclose a display device comprising any one of the display modules as described in the foregoing embodiments of the present application.

[0078] Specifically, the display device can be a computer display, a television, a billboard, a laser printer with display function, a telephone, a mobile phone, a personal digital assistant (PDA), a laptop computer, a digital camera, a camcorder, a viewfinder, a vehicle, a large-area wall, a screen of a theater or a sports stadium sign, etc.
