Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and display device. Background Technology

[0002] In related technologies, the display module of a display device typically includes a backplate and a lamp plate mounted on the backplate. The lamp plate has light sources such as LEDs that provide display light for the display device. The backplate includes positioning posts, which are inserted into positioning holes on the lamp plate to achieve positioning of the lamp plate.

[0003] However, the back panel usually includes structures such as flanges and reinforcing ribs, which makes the structure of the back panel more complex. This makes it difficult to ensure that the back panel has high processing precision, and thus makes it difficult to achieve accurate positioning and installation of the lamp panel. Utility Model Content

[0004] This application provides a display module and display device that makes it easier to accurately position and install the light panel.

[0005] In a first aspect, this application provides a display module, comprising:

[0006] Back panel;

[0007] A positioning structure is disposed on the inner side of the back plate and connected to the back plate; and,

[0008] A light panel is disposed on the side of the positioning structure away from the back plate. Both the light panel and the positioning structure are planar plates, and the light panel is arranged parallel to the positioning structure; or, both the light panel and the positioning structure are curved plates, and the curvature of the light panel is the same as the curvature of the positioning structure.

[0009] In this configuration, one of the lamp panel and the positioning structure is provided with a plurality of first positioning posts, and the other of the lamp panel and the positioning structure is provided with a plurality of first positioning holes. The first positioning posts correspond one-to-one with the first positioning holes and are inserted into the first positioning holes.

[0010] In some embodiments of this application, both the back plate and the positioning structure are sheet metal panels. A large number of light panels can be mounted simultaneously on a single positioning structure, thereby meeting the needs of large-size display devices.

[0011] In some embodiments of this application, the first positioning hole is a square hole, and there is a movable gap between the first positioning post and the inner wall of the first positioning hole. This allows the first positioning post to be easily moved left and right along the bottom wall of the first positioning hole to adjust the position of the lamp panel.

[0012] In some embodiments of this application, the positioning structure has a plurality of first magnetic elements on the side near the lamp panel, and the lamp panel has a plurality of second magnetic elements on the side near the positioning structure. The first magnetic elements and the second magnetic elements are magnetically connected. This prevents the lamp panel from shaking during use and makes the installation and removal of the lamp panel more convenient.

[0013] In some embodiments of this application, the second magnetic element is stacked with the first magnetic element, and at least a portion of the second magnetic element is disposed at the edge of the lamp panel and arranged at intervals along the periphery of the lamp panel. This ensures that the flatness of the lamp panel is only related to the flatness of each of the first magnetic elements, thereby guaranteeing the flatness of the lamp panel and making the installation of the lamp panel more precise.

[0014] In some embodiments of this application, the display module includes multiple light panels, which are sequentially spliced ​​together with a splicing gap between adjacent light panels. At least a portion of the first magnetic component is positioned opposite the splicing gap. One of the first magnetic components located in the splicing gap is stacked and magnetically connected to the second magnetic components on the two adjacent light panels. By providing support for two adjacent light panels simultaneously through the first magnetic component located in the splicing gap, the flatness and installation height of the two adjacent light panels can be ensured.

[0015] In some embodiments of this application, the display module further includes: a first connector located between the back plate and the positioning structure, the positioning structure being connected to the back plate via the first connector, the back plate, the first connector, and the positioning structure defining a receiving cavity; and a receiving card located in the receiving cavity and electrically connected to the lamp board; wherein, one of the positioning structure and the receiving card is provided with a plurality of second positioning holes, and the other of the positioning structure and the receiving card is provided with a plurality of second positioning posts, the second positioning posts corresponding one-to-one with the second positioning holes and inserted into the second positioning holes. The accuracy of the receiving card positioning installation depends on the processing accuracy of the positioning structure, making it easier to achieve precise positioning and installation of the receiving card, thereby ensuring the installation accuracy of the receiving card and thus ensuring the connection accuracy between the receiving card and the lamp board.

[0016] In some embodiments of this application, the positioning structure includes: a first plate connected to the back plate, the first plate having a clearance opening; a second plate located at the clearance opening and detachably connected to the first plate, and the receiving card located between the back plate and the second plate. When the receiving card needs to be inspected or replaced, the second plate can be disassembled to expose the receiving card, and the receiving card can be inspected or replaced through the clearance opening.

[0017] In some embodiments of this application, the display module further includes: a second connector located in the receiving cavity and opposite to the lamp panel; the second connector is connected to the first connector; a second plate is detachably connected to the second connector; and the side of the second plate facing the lamp panel is flush with the side of the first plate facing the back plate. This allows the inner side of the second plate to be flush with the inner side of the first plate, and the outer side of the second plate to be flush with the outer side of the first plate, thereby providing more precise positioning for the lamp panel and the receiving card.

[0018] In some embodiments of this application, both the first plate and the second plate are provided with one of the first positioning hole and the first positioning post, and both the first plate and the second plate are provided with one of the second positioning hole and the second positioning post. This makes the distribution area of ​​the first positioning hole, the first positioning post, the second positioning hole, and the second positioning post larger, which can further improve the positioning accuracy of the lamp board and the receiver card.

[0019] In some embodiments of this application, a first connector is provided on the side of the receiving card near the positioning structure, and a second connector is provided on the side of the lamp board near the positioning structure. A through hole is formed between the second board body and the first board body. The second connector passes through the through hole and is inserted into the first connector to achieve an electrical connection between the receiving card and the lamp board. The lamp board and the receiving card can be positioned and electrically connected through the first connector and the second connector. The positioning structure ensures accurate positioning of the lamp board and the receiving card.

[0020] Secondly, this application also provides a display device, including a plurality of display modules as described in any one of the above embodiments, wherein the plurality of display modules are arranged in an array.

[0021] The beneficial effects of this application are as follows: the lamp panel is installed and positioned by the first positioning post and the first positioning hole. The accuracy of the lamp panel positioning and installation depends on the processing accuracy of the positioning structure. Compared with the back plate, the positioning structure is simpler. When the first positioning post is formed on the lamp panel, only holes need to be made in the positioning structure. The processing and forming of the positioning structure is easier, making it easier to achieve higher processing accuracy. This makes it easier to accurately position and install the lamp panel, thereby ensuring the installation accuracy and assembly accuracy of the lamp panel. In addition, the processing cost of the positioning structure is also lower, which can reduce the production cost of the display module. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] In related technologies, display devices are typically large-sized devices formed by splicing together multiple arrayed display modules. They can be used in both outdoor and indoor scenarios and have advantages such as large size, high brightness, and long lifespan. A display module usually includes a back panel and a lamp panel mounted on the back panel. The lamp panel contains light sources such as LEDs that provide light to the display device. The back panel includes positioning posts, which are inserted into positioning holes on the lamp panel to achieve positioning. Furthermore, for large-sized display devices, a single display module typically includes multiple lamp panels, which are spliced ​​together to form lamp panel modules of different sizes. High gap tolerances are required at the splicing points of the lamp panels, and related technologies typically use positioning posts and positioning holes to ensure the assembly accuracy of the lamp panels.

[0033] However, the back panel usually includes structures such as flanges and reinforcing ribs, which makes the structure of the back panel more complex. This makes it difficult to ensure that the back panel has high processing precision, and thus makes it difficult to achieve accurate positioning and installation of the lamp panel.

[0034] In view of the above-mentioned technical problems, this application provides a display module and a display device, such as Figures 1 to 3 As shown, the display module includes a back panel 10, a positioning structure 20, and a light panel 31.

[0035] The back plate 10 is used to provide support and installation space for the positioning structure 20. The back plate 10 may have structures such as flanges, reinforcing ribs and heat dissipation holes. The specific structure of the back plate 10 can be selected according to actual needs.

[0036] The positioning structure 20 is disposed on the inner side of the back plate 10 and connected to the back plate 10. The inner side of the back plate 10 refers to the side of the back plate 10 facing the display surface when the display module is applied in the display device. The positioning structure 20 is used to provide support for the lamp panel 31.

[0037] The lamp plate 31 is located on the side of the positioning structure 20 away from the back plate 10. The lamp plate 31 is arranged parallel to the positioning structure 20. One of the lamp plate 31 and the positioning structure 20 is provided with a plurality of first positioning posts 51, and the other of the lamp plate 31 and the positioning structure 20 is provided with a plurality of first positioning holes 52. The first positioning posts 51 and the first positioning holes 52 correspond one-to-one and are inserted into the first positioning holes 52.

[0038] It should be noted that the lamp board 31 is a device equipped with LED beads or light strips, and the light source can be located on the side of the lamp board 31 away from the positioning structure 20; the first positioning post 51 can be a tin-plated positioning post. When the first positioning post 51 is set on the lamp board 31, the first positioning post 51 is located on the side of the lamp board 31 closer to the positioning structure 20. The first positioning post 51 can be integrally formed with the body of the lamp board 31, or the first positioning post 51 can be formed separately from the body of the lamp board 31 and then spliced ​​by welding, gluing, riveting, threaded connection or other methods. In this case, the first positioning hole 52 is set. On the positioning structure 20, the first positioning hole 52 can be a through hole that penetrates the positioning structure 20 or a groove that does not penetrate the positioning structure 20; when the first positioning post 51 is set on the positioning structure 20, the first positioning post 51 is located on the side of the positioning structure 20 close to the lamp panel 31. The first positioning post 51 can be integrally formed with the positioning structure 20, or the first positioning post 51 can be formed separately from the positioning structure 20 and then spliced ​​by welding, gluing, riveting, threaded connection or other methods. In this case, the first positioning hole 52 is set on the lamp panel 31, and the first positioning hole 52 is a groove that does not penetrate the lamp panel 31.

[0039] Specifically, both the lamp panel 21 and the positioning structure 20 are planar plates, and the lamp panel 21 and the positioning structure 20 are arranged in parallel. That is, the side of the lamp panel 21 facing the display surface and the side facing away from the display surface are both planar, and the side of the positioning structure 20 facing the display surface and the side facing away from the display surface are both planar. Alternatively, both the lamp panel 21 and the positioning structure 20 are curved plates, and the curvature of the lamp panel 21 and the positioning structure 20 is the same. That is, the side of the lamp panel 21 facing the display surface and the side facing away from the display surface are both curved, and the side of the positioning structure 20 facing the display surface and the side facing away from the display surface are both curved, and the curvature of the curved surface on the lamp panel 21 is the same as the curvature of the positioning structure 20.

[0040] It is understood that in this application, the shape of the lamp panel 31 is adapted to the shape of the positioning structure 20. The lamp panel 31 is installed and positioned by the first positioning post 51 cooperating with the first positioning hole 52. The positioning accuracy of the lamp panel 31 depends on the processing accuracy of the positioning structure 20. Compared with the back plate 10, the structure of the positioning structure 20 is simpler. For example, when the first positioning post 51 is formed on the lamp panel 31, only a hole needs to be made in the positioning structure 20. The processing and forming of the positioning structure 20 is easier, making it easier to achieve higher processing accuracy. This makes it easier to accurately position and install the lamp panel 31, thereby ensuring the installation accuracy and assembly accuracy of the lamp panel 31. In addition, the processing cost of the positioning structure 20 is also lower, which can reduce the production cost of the display module.

[0041] In some embodiments, both the back plate 10 and the positioning structure 20 are sheet metal sheets, meaning they are metal sheets formed by sheet metal processing. It should be noted that compared to die casting back plates formed using die casting processes in related technologies, die casting requires die casting molds and involves more complex machining processes, resulting in higher manufacturing costs. Furthermore, due to the size limitations of the die casting molds, the size of die casting back plates is typically smaller; a single die casting back plate can usually only accommodate a limited number of lamp panels 31. When applied to large-size display devices, multiple die casting back plates typically need to be spliced ​​together, making it difficult to guarantee the splicing accuracy. In this embodiment, however, both the back plate 10 and the positioning structure 20 are sheet metal sheets, which have simpler processing steps and are more feasible to manufacture. It offers high performance and lower cost, and the sheet metal body can be made to a very large size, allowing a large number of lamp panels 31 to be installed simultaneously on a single positioning structure 20. This reduces the number of back panels 10 while meeting the needs of large-size display devices, thus solving the problem of difficulty in ensuring the splicing accuracy of die-cast back panels. In addition, considering the issue that the processing accuracy of sheet metal processing is lower than that of die-casting processing, the simple structure of the positioning structure 20 allows the positioning structure 20 to be laser-cut in one piece to ensure the processing accuracy of the positioning structure 20, thereby ensuring the positioning and installation accuracy of the lamp panels 31.

[0042] In some embodiments, the first positioning hole 52 is a square hole, and there is a movable gap between the first positioning post 51 and the inner wall of the first positioning hole 52, so that the lamp panel 31 can have a certain amount of room to move when installing the lamp panel 31, thereby allowing the position of the lamp panel 31 to be adjusted. In addition, since the first positioning hole 52 is a square hole, when assembling the display module, the back plate 10 can be hung on the pre-fixed device first. At this time, the first positioning post 51 will contact the bottom wall surface of the first positioning hole 52 under the action of gravity. Since the bottom wall surface of the first positioning hole 52 is flat, the first positioning post 51 can easily move left and right along the bottom wall surface of the first positioning hole 52 to adjust the position of the lamp panel 31. It should also be noted that the size of the movable gap is generally small, and the specific size of the movable gap can be selected according to actual needs. The cross-sectional shape of the first positioning post 51 can be square to match the shape of the first positioning hole 52, or the cross-sectional shape of the first positioning post 51 can be circular.

[0043] It should also be noted that there is a movable gap between the inner wall of the first positioning post 51 and the first positioning hole 52, which can also achieve gap control. Because the surface area of ​​the positioning structure 20 and the lamp plate 31 is usually large, laser punching is usually required when manufacturing the positioning structure 20 and the lamp plate 31, and the first positioning hole 52 is formed at the same time by laser punching. If there is no movable gap between the inner wall of the first positioning post 51 and the first positioning hole 52, the first positioning hole 52 and the first positioning post 51 will not fit precisely. Since the relative position tolerance of the first positioning hole 52 and the first positioning post 51 is difficult to control during manufacturing, it is possible that the hole diameter of the first positioning hole 52 is too large or too small relative to the size of the first positioning hole 52, which may lead to the problem of difficulty in positioning and installing the first positioning hole 52 and the first positioning post 51 when installing the lamp plate 31.

[0044] like Figure 4 and Figure 5 As shown in some embodiments of this application, the positioning structure 20 has a plurality of first magnetic elements 53 on the side near the lamp panel 31, and the lamp panel 31 has a plurality of second magnetic elements 54 on the side near the positioning structure 20. The first magnetic elements 53 and the second magnetic elements 54 are magnetically connected to each other to attract and fix the lamp panel 31 onto the positioning structure 20, preventing the lamp panel 31 from shaking during use and making it easier to install and remove the lamp panel 31. The first magnetic elements 53 can be magnets, and can be disc-shaped or other shapes; the second magnetic elements 54 can be tin-plated iron sheets, and can be disc-shaped or other shapes.

[0045] Furthermore, the second magnetic element 54 is stacked with the first magnetic element 53, and at least a portion of the second magnetic element 54 is disposed at the edge of the lamp panel 31, and is arranged at intervals along the periphery of the lamp panel 31. It can be understood that... Figure 5 Taking the shown perspective as an example, the lamp panel 31 is supported by the first magnetic component 53, so that the flatness of the lamp panel 31 is only related to the flatness of each of the first magnetic components 53. The first magnetic component 53 is small in size, easy to manufacture, and easy to install, which can ensure that each of the first magnetic components 53 has high processing precision and flatness, thereby ensuring the flatness of the lamp panel 31 and making the installation of the lamp panel 31 more accurate. In addition, the second magnetic component 54 set at the edge of the lamp panel 31 can fix and support the edge of the lamp panel 31 and prevent the edge of the lamp panel 31 from lifting.

[0046] Furthermore, such as Figure 1 and Figure 4As shown, the display module includes multiple light panels 31, which are sequentially spliced ​​together. A splicing gap 32 exists between adjacent light panels 31. At least a portion of the first magnetic element 53 is positioned opposite the splicing gap 32. One of the first magnetic elements 53 located in the splicing gap 32 is stacked and magnetically connected to the second magnetic elements 54 on the two adjacent light panels 31. It can be understood that adjacent light panels 31 share a common first magnetic element 53. Since the flatness of the light panel 31 depends on the flatness of the first magnetic element 53, by simultaneously providing support for the two adjacent light panels 31 through the first magnetic element 53 located in the splicing gap 32, the consistency of the flatness and installation height of the two adjacent light panels 31 can be ensured.

[0047] It should also be noted that, see Figure 4 As shown, multiple first magnetic elements 53 located in the splicing gap 32 can be arranged at intervals along the extension direction of the splicing gap 32. The first magnetic elements 53 located at the corner splicing points of four adjacent light panels 31 can be stacked and magnetically connected with the second magnetic elements 54 on the four adjacent light panels 31.

[0048] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the display module further includes a first connector 61 and a receiving card 40; the first connector 61 is located between the back plate 10 and the positioning structure 20, the positioning structure 20 is connected to the back plate 10 through the first connector 61, the back plate 10, the first connector 61 and the positioning structure 20 define a receiving cavity 70, the first connector 61 is used to fix the positioning structure 20 to the back plate 10, the first connector 61 can be a sheet metal fixing strip, and the positioning structure 20 can be connected to the first connector 61 by fasteners such as rivets and bolts; the receiving card 40 is located in the receiving cavity 70 and is electrically connected to the lamp board 31, the receiving card 40 can provide power to the lamp board 31 and provide network load functions.

[0049] The positioning structure 20 and the receiving card 40 each have multiple second positioning holes 56, and the other has multiple second positioning posts 55. Each second positioning post 55 corresponds to and is inserted into one of the second positioning holes 56. The receiving card 40 is housed within the receiving cavity 70 between the positioning structure 20 and the back plate 10. This allows the positioning structure 20 to provide protection for the receiving card 40. The receiving card 40 is positioned and installed by the cooperation of the second positioning posts 55 and the second positioning holes 56. The accuracy of the positioning and installation of the receiving card 40 depends on the machining accuracy of the positioning structure 20. More precise positioning and installation of the receiving card 40 ensures its installation accuracy and, consequently, the connection accuracy between the receiving card 40 and the light board 31.

[0050] It should also be noted that the second positioning post 55 can be a copper nut post, and the second positioning post 55 can be provided with a threaded hole. The receiving card 40 can be fixed to the second positioning post 55 by inserting a screw into the threaded hole. When the second positioning post 55 is set on the receiving card 40, the second positioning post 55 is located on the side of the receiving card 40 closer to the positioning structure 20. The second positioning post 55 can be integrally formed with the plate of the receiving card 40, or the second positioning post 55 can be formed separately from the plate of the receiving card 40 and then spliced ​​by welding, gluing, riveting, threaded connection or other methods. In this case, the second positioning hole 56 is set on the positioning structure 20. The second positioning hole 56 can be a through hole that penetrates the positioning structure 20 or a groove that does not penetrate the positioning structure 20. When the second positioning post 55 is set on the positioning structure 20, the second positioning post 55 is located on the side of the positioning structure 20 closer to the receiving card 40. The second positioning post 55 can be integrally formed with the positioning structure 20, or the second positioning post 55 can be formed separately from the positioning structure 20 and then spliced ​​by welding, gluing, riveting, threaded connection or other methods. In this case, the second positioning hole 56 is set on the receiving card 40. The second positioning hole 56 can be a through hole that penetrates the receiving card 40 or a groove that does not penetrate the receiving card 40.

[0051] In some embodiments, the positioning structure 20 includes a first plate 21 and a second plate 22; the first plate 21 is connected to the back plate 10 and has a recess opening 211; the second plate 22 is located at the recess opening 211 and is detachably connected to the first plate 21, and the receiving card is located between the back plate 10 and the second plate 22. When it is necessary to repair or replace the receiving card 40, the second plate 22 can be removed to expose the receiving card 40, and the receiving card 40 can be repaired or replaced through the recess opening 211.

[0052] It should also be noted that when the lamp panel 31 is a planar plate, the first plate 21 and the second plate 22 are both planar plates and are parallel to the lamp panel 31; when the lamp panel 31 is a curved plate, the first plate 21 and the second plate 22 are both curved plates and have the same curvature as the lamp panel 31.

[0053] In some embodiments, both the first plate 21 and the second plate 22 are provided with one of a first positioning hole 52 and a first positioning post 51, and both the first plate 21 and the second plate 22 are provided with one of a second positioning hole 56 and a second positioning post 55. Increasing the number of the first positioning holes 52, second positioning holes 56, first positioning posts 51, and second positioning posts 55, and making their distribution area larger, can further improve the positioning accuracy of the lamp board 31 and the receiver card 40.

[0054] like Figure 5 and Figure 6As shown, in some embodiments, the second connector 62 is located in the receiving cavity 70 and is opposite to the lamp panel 31. The second connector 62 is connected to the first connector 61. The second plate 22 is detachably connected to the second connector 62. The side of the second plate 22 facing the lamp panel 31 is flush with the side of the first plate 21 facing the back plate 10. It should be noted that the second connector 62 can also be a sheet metal fixing strip. The second plate 22 is detachably connected to the first plate 21 through the first connector 61 and the second connector 62. The second connector 62 can be connected to the first connector 61 by fasteners such as rivets and bolts, and the second plate 22 can be connected to the first connector 61 by fasteners such as bolts, so that the second plate 22 can be disassembled. In addition, the second connector 62 can provide support for the second plate 22, so that the inner side of the second plate 22 can be flush with the inner side of the first plate 21, and the outer side of the second plate 22 can be flush with the outer side of the first plate 21, thereby providing more accurate positioning for the lamp board 31 and the receiver card 40.

[0055] In some embodiments, a first connector 57 is provided on the side of the receiving card 40 near the positioning structure 20, and a second connector 58 is provided on the side of the lamp board 31 near the positioning structure 20 (e.g., ...). Figure 4 A through hole 23 is formed between the second plate and the first plate. The second connector 58 passes through the through hole 23 and is inserted into the first connector 57 to achieve electrical connection between the receiver card 40 and the lamp board 31. It can be understood that the lamp board 31 and the receiver card 40 can be positioned and electrically connected through the first connector 57 and the second connector 58. The positioning structure 20 ensures accurate positioning of the lamp board 31 and the receiver card 40, thereby allowing the first connector 57 and the second connector 58 to be accurately inserted. It should also be noted that the second plate 22 can be cross-shaped; depending on actual needs, the second plate 22 can also be elongated, triangular, or other shapes.

[0056] Secondly, based on the aforementioned display modules, this application also provides a display device. The display device includes multiple display modules as described in any of the above embodiments, the multiple display modules are arranged in an array, and adjacent display modules are spliced ​​together. The display device can be an LED (Light Emitting Diode panel) display screen.

[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
