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] 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. The display modules of a display device usually include a back panel and a lamp panel mounted on the back panel. The lamp panel provides display light to the display device. In addition, the display module usually also includes hardware components such as a power supply and network load unit to provide power to the lamp panel and provide network access.

[0003] In related technologies, in order to facilitate hardware maintenance, a bottom bezel is usually set on the bottom side of the display device, and the hardware components are installed inside the bottom bezel. However, the bottom bezel reduces the display area of ​​the display device, thereby reducing the display effect. Utility Model Content

[0004] This application provides a display module and display device that eliminates the need for an additional hardware component to provide space for the bottom bezel, thereby increasing the display area and enhancing the display effect of the display device.

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

[0006] Back panel;

[0007] Hardware components are disposed on the inner side of the backplate and connected to the backplate;

[0008] A front maintenance structure, disposed on the side of the hardware assembly away from the back panel, the front maintenance structure including a front maintenance plate detachably connected to the back panel; and,

[0009] A light panel is disposed on the side of the front maintenance panel away from the back panel and is connected to the front maintenance panel. The light panel is electrically connected to the hardware components.

[0010] In some embodiments of this application, both the back panel and the front maintenance panel are sheet metal sheets. Sheet metal sheets have simple processing steps, high manufacturing feasibility, and lower cost. Furthermore, sheet metal sheets can be made to a very large size, allowing the back panel to have sufficient volume to accommodate hardware components, thus eliminating the need for an additional bottom bezel.

[0011] In some embodiments of this application, a positioning member is provided on the side of the back plate facing the front maintenance plate. The positioning member has a first positioning post, and the front maintenance plate has a first positioning hole through which the first positioning post passes. The first positioning post on the positioning member can be used to pre-position the front maintenance plate, making the positioning and installation of the front maintenance plate more convenient.

[0012] In some embodiments of this application, the front maintenance plate includes two first side edges and two second side edges. The two first side edges are arranged along a first direction, and the two second side edges are arranged along a second direction. The second side edges are adjacent to the first side edges, and the first direction and the second direction intersect. A connecting structure is provided between the first side edges and the back plate, and the first side edges are detachably connected to the back plate through the connecting structure. The positioning member is disposed between the second side edges and the back plate, and the first positioning hole is disposed on the second side edge. This design ensures that all four sides of the front maintenance plate are fixed and limited, making the installation of the front maintenance plate more stable and preventing the edges of the front maintenance plate from warping.

[0013] In some embodiments of this application, a second positioning post is provided on the side of the back plate facing the front maintenance plate, and a second positioning hole is provided on the front maintenance plate for the second positioning post to pass through. This increases the number of positioning points on the front maintenance plate, thereby making the installation and positioning of the front maintenance plate more accurate.

[0014] In some embodiments of this application, the display module further includes a receiving card located between the back panel and the front maintenance board. The receiving card is connected to the front maintenance board and electrically connected to the lamp board and the hardware components. The receiving card can be removed together with the front maintenance board, making the inspection and maintenance of the hardware components more convenient.

[0015] In some embodiments of this application, the front maintenance plate includes: a first plate body detachably connected to the back plate, the first plate body having a clearance opening; a second plate body located at the clearance opening and detachably connected to the first plate body; and a receiver card located between the back plate and the second plate body, and detachably connected to the first plate body and / or the second plate body. When the receiver card needs to be inspected or replaced separately, the second plate body can be disassembled to expose the receiver card, and the receiver card can be inspected or replaced through the clearance opening.

[0016] In some embodiments of this application, the front maintenance structure further includes a connecting plate located on the side of the front maintenance plate near the back plate, wherein the first plate is detachably connected to the second plate via the connecting plate. The detachable connection between the first and second plates is achieved by the connecting plate, which is hidden inside the front maintenance plate, and the connecting plate can provide support for both the first and second plates.

[0017] In some embodiments of this application, the backplate includes: a main structure; and a back frame connected to the main structure and protruding away from the front maintenance plate to form a receiving cavity. The receiving cavity has an opening on the side facing the front maintenance plate, and the hardware component is located within the receiving cavity. The receiving cavity formed by the back frame provides a larger receiving space for the hardware component.

[0018] In some embodiments of this application, the front maintenance structure includes a plurality of front maintenance panels, which are respectively disposed opposite to different portions of the back panel. Multiple front maintenance panels are spliced ​​together to form maintenance panel structures of different sizes to meet the needs of display devices of different sizes.

[0019] 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.

[0020] The beneficial effects of this application are as follows: the hardware component is sandwiched between the back plate and the front maintenance plate, and the space formed by the back plate and the front maintenance plate can be used to accommodate the hardware component. The front maintenance plate provides limitation and protection for the hardware component, and the front maintenance plate is detachably connected to the back plate. When the hardware component needs to be inspected and maintained, the front maintenance plate can be removed to expose the hardware component for inspection and maintenance, making the inspection and maintenance of the hardware component more convenient. As a result, there is no need to set up a bottom bezel to provide space for the hardware component, thereby increasing the display area of ​​the display device, enhancing the display effect of the display device, and making the display device closer to a pure display panel.

[0033] 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.

[0034] This application provides a display module and display device to solve the problem in the related art that, in order to facilitate hardware maintenance, a bottom bezel is usually set on the bottom side of the display device and the hardware components are installed inside the bottom bezel. However, the setting of the bottom bezel reduces the display area of ​​the display device, thereby reducing the display effect of the display device.

[0035] Firstly, this application provides a display module, such as... Figures 1 to 3 As shown, the display module includes a backplate 10, hardware components 20, a front maintenance structure 30, and a light panel 40.

[0036] The back plate 10 provides support and installation space for the hardware components 20 and the front maintenance structure 30. The hardware components 20 are located inside the back plate 10 and connected to it. The hardware components 20 can be fixed to the back plate 10 by threaded fasteners (such as screws). The hardware components 20 may include electronic devices such as power supplies for powering the lamp board 40. The inside 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 front maintenance structure 30 is located on the side of the hardware components 20 away from the back plate 10. The front maintenance structure 30 includes a front maintenance plate 31 that is detachably connected to the back plate 10. The front maintenance plate 31 is a plate structure that can provide support for the lamp board 40. The lamp board 40 is located on the side of the front maintenance plate 31 away from the back plate 10 and connected to it. The lamp board 40 is electrically connected to the hardware components 20. The lamp board 40 is a device with LED beads or light strips as light sources. The light sources are located on the side of the lamp board 40 away from the front maintenance plate 31.

[0037] It is understood that in this application, the hardware component 20 is disposed between the back plate 10 and the front maintenance plate 31. The space formed by the back plate 10 and the front maintenance plate 31 can accommodate the hardware component 20. The front maintenance plate 31 provides limiting and protection for the hardware component 20. Furthermore, the front maintenance plate 31 is detachably connected to the back plate 10, so that when the hardware component 20 needs to be inspected and maintained, the front maintenance plate 31 can be removed to expose the hardware component 20 for inspection and maintenance. This makes the inspection and maintenance of the hardware component 20 more convenient. As a result, there is no need to set up a lower bezel to provide space for the hardware component 20, thereby increasing the display area of ​​the display device, enhancing the display effect of the display device, and making the display device closer to a pure display panel.

[0038] In some embodiments, both the backplate 10 and the front maintenance plate 31 are sheet metal sheets, meaning they are metal sheets formed by sheet metal processing. It should be noted that compared to die-casting backplates, which require die-casting molds and involve more complex machining processes, resulting in higher manufacturing costs, and due to the size limitations of the die-casting molds, the die-cast backplates are typically smaller, making it difficult to provide sufficient space for the hardware component 20. In this embodiment, however, both the backplate 10 and the metal sheet are sheet metal sheets. Sheet metal sheets have simpler processing steps, higher manufacturing feasibility, and lower costs. Furthermore, sheet metal sheets can be made to a very large size, allowing the backplate 10 to have sufficient volume to accommodate the hardware component 20, thus eliminating the need for an additional bottom bezel.

[0039] In some embodiments, the front maintenance structure 30 includes a plurality of front maintenance plates 31, which are respectively disposed opposite to different parts of the back plate 10. The plurality of front maintenance plates 31 are spliced ​​together to form maintenance plate structures of different sizes to meet the needs of display modules of different sizes.

[0040] like Figure 3 and Figure 4 As shown in some embodiments of this application, a positioning member 50 is provided on the side of the back plate 10 facing the front maintenance plate 31. The positioning member 50 has a first positioning post 51, and the front maintenance plate 31 is provided with a first positioning hole 311 through which the first positioning post 51 passes. It should be noted that when installing the front maintenance plate 31, the back plate 10 can be vertically hung on the mounting device first, and then the positioning member 50 can be fixed to the back plate 10 before the front maintenance plate 31 is installed on the back plate 10. When the front maintenance plate 31 is installed on the back plate 10, the first positioning post 51 on the positioning member 50 can be used to provide a pre-position for the front maintenance plate 31, making the positioning and installation of the front maintenance plate 31 more convenient.

[0041] The positioning element 50 can be a positioning plate, and multiple first positioning posts 51 can be provided on the positioning element 50. At least two first positioning posts 51 are located at opposite ends of the positioning plate, so that when the front maintenance structure 30 includes multiple front maintenance plates 31 spliced ​​together, two adjacent front maintenance plates 31 can be connected to a first positioning post 51 on a positioning element 50, thereby realizing the connection of two adjacent front maintenance plates 31 and preventing relative displacement of two adjacent front maintenance plates 31.

[0042] In some embodiments, the front maintenance panel 31 includes two first side edges 312 and two second side edges 313. The two first side edges 312 are arranged along a first direction XX, and the two second side edges 313 are arranged along a second direction YY. The second side edges 313 are arranged adjacent to the first side edges 312. The first direction XX and the second direction YY intersect. The first direction XX can be perpendicular to the second direction YY or form an angle of other angles. The first direction XX can be the extension direction of the second side edge 313, and the second direction YY can be the extension direction of the first side edge 312.

[0043] A connecting structure 60 is provided between the first side 312 and the back plate 10, allowing the first side 312 to be detachably connected to the back plate 10. A positioning member 50 is disposed between the second side 313 and the back plate 10, and a first positioning hole 311 is disposed on the second side 313. It can be understood that the connecting structure 60 provides a connection limit for the first side 312 of the front maintenance plate 31, while the positioning member 50 provides a connection limit for the second side 313 of the front maintenance plate 31, ensuring that all four sides of the front maintenance plate 31 are fixed and secured. This makes the installation of the front maintenance plate 31 more stable and prevents the edges of the front maintenance plate 31 from warping.

[0044] Furthermore, the two positioning members 50, which are respectively set near the two corners of the front maintenance plate 31, are provided corresponding to the two second side edges 313. The positioning members 50 can be used to position and limit the marked position of the front maintenance plate 31, so that the positioning of the front maintenance plate is more accurate, and at the same time, the corners of the front maintenance plate 31 are prevented from lifting up.

[0045] Furthermore, the connecting structure 60 includes a connecting rib extending along the extension direction of the first side 312. The connecting rib can be fixed to the back plate 10 by fasteners such as rivets and bolts. The front maintenance plate 31 can be detachably connected to the connecting rib by fasteners such as screws, thereby achieving a detachable connection with the back plate 10.

[0046] In some embodiments, a second positioning post 11 is provided on the side of the back plate 10 facing the front maintenance plate 31, and a second positioning hole 314 is provided on the front maintenance plate 31 for the second positioning post 11 to pass through, which can increase the positioning points of the front maintenance plate 31, thereby making the installation positioning of the front maintenance plate 31 more accurate. The second positioning post 11 can be integrally formed with the back plate 10, or it can be formed separately from the back plate 10 and then spliced ​​together by welding, gluing, riveting, threaded connection, or other methods.

[0047] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the display module further includes a receiver card 70, which is located between the back plate 10 and the front maintenance plate 31. The receiver card 70 is connected to the front maintenance plate 31 and electrically connected to the lamp board 40 and the hardware component 20. The receiver card 70 can provide power to the lamp board 40 and provide network load functions. By connecting the receiver card 70 to the front maintenance plate 31, the front maintenance plate 31 provides support for the receiver card 70. When the hardware component 20 needs to be inspected and maintained, the receiver card 70 can be removed together when the front maintenance plate 31 is removed, making the inspection and maintenance of the hardware component 20 more convenient.

[0048] In some embodiments, the front maintenance plate 31 may be provided with a plurality of first mounting holes 315, and the receiver card 70 may be provided with a plurality of first mounting posts 71. The first mounting posts 71 correspond one-to-one with the first mounting holes 315 and are inserted into the first mounting holes 315. The receiver card 70 can be installed and positioned by cooperating with the first mounting posts 71 on the front maintenance plate 31 and the first mounting holes 315 on the front maintenance plate 31. The positioning and installation accuracy of the receiver card 70 depends on the machining accuracy of the front maintenance plate 31. It is easier to achieve accurate positioning and installation of the receiver card 70, thereby ensuring the installation accuracy of the receiver card 70 and the connection accuracy between the receiver card 70 and the lamp board 40. The first mounting posts 71 may be copper nut posts, and the first mounting posts 71 may be provided with threaded holes. The receiver card 70 is fixed to the first mounting post 71 by inserting screws into the threaded holes.

[0049] In some embodiments, the front maintenance panel 31 includes a first panel 316 and a second panel 317; the first panel 316 is detachably connected to the back panel 10 and has a recess opening 316a; the second panel 317 is located at the recess opening 316a and is detachably connected to the first panel 316, and the receiver card is located between the back panel 10 and the second panel 317, and is detachably connected to the first panel 316 and / or the second panel 317. When it is necessary to inspect or replace the receiver card 70 separately, the second panel 317 can be removed to expose the receiver card 70, and the receiver card 70 can be inspected or replaced through the recess opening 316a.

[0050] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the front maintenance structure 30 further includes a connecting plate 32. The connecting plate 32 is located on the side of the front maintenance plate 31 near the back plate 10, and the first plate 316 is detachably connected to the second plate 317 via the connecting plate 32. It can be understood that by using the connecting plate 32, which is hidden inside the front maintenance plate 31 (on the side of the front maintenance plate 31 near the back plate 10), the detachable connection between the first plate 316 and the second plate 317 can be achieved. The connecting plate 32 can provide support for the first plate 316 and the second plate 317, and make the inner side of the first plate 316 flush with the inner side of the second plate 317, and the outer side of the first plate 316 flush with the outer side of the second plate 317, thereby providing more precise positioning for the lamp board 40 and the receiver card 70.

[0051] The connecting plate 32 can be fixed to the first plate 316 as a whole by rivets, and the second plate 317 can be detachably connected to the connecting plate 32 by screws or other fasteners, thereby realizing the detachability of the first plate 316 and the second plate 317.

[0052] It should also be noted that the first plate 316 can be connected to the back plate 10 by screws passing sequentially through the first plate 316 and the connecting plate 32 and connecting to the connecting structure 60. Alternatively, the second plate 317 can be connected to the connecting plate 32 by screws passing sequentially through the second plate 317. When only the second plate 317 needs to be disassembled, the screws can be removed from the outside of the second plate 317 (the side of the front maintenance plate 31 away from the back plate 10) to separate the second plate 317 from the connecting plate 32, thus separating the second plate 317 from the first plate 316. When the entire front maintenance plate 31 needs to be disassembled, the first plate 316 can be directly separated from the back plate 10. In this case, the second plate 317 is still connected to the first plate 316 via the connecting plate 32, thus allowing the front maintenance plate 31 to be disassembled.

[0053] like Figure 8 As shown, in some embodiments, the back panel 10 includes a main structure 12 and a back frame 13. The back frame 13 is connected to the main structure 12 and protrudes in a direction away from the front maintenance panel 31 to form a receiving cavity 14. The receiving cavity 14 is opened on the side facing the front maintenance panel 31. The hardware component 20 is located in the receiving cavity 14 so as to provide a larger receiving space for the hardware component 20 by utilizing the receiving cavity 14 formed by the back frame 13.

[0054] like Figure 9 As shown, in some embodiments, a plurality of second mounting posts 41 are provided on the side of the lamp panel 40 near the front maintenance plate 31, and a second mounting hole 318 is provided on the front maintenance plate 31. The second mounting posts 41 correspond one-to-one with the second mounting holes 318 and are inserted into the second mounting holes 318, thereby realizing the positioning and installation of the lamp panel 40.

[0055] In some embodiments, a plurality of first magnetic elements 81 are provided on the side of the front maintenance plate 31 near the lamp plate 40, and a plurality of second magnetic elements 82 are provided on the side of the lamp plate 40 near the front maintenance plate 31. The first magnetic elements 81 and the second magnetic elements 82 are magnetically connected. This prevents the lamp plate 40 from shaking during use and makes it easier to install and remove the lamp plate 40.

[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, with the multiple display modules arranged in an array and adjacent display modules spliced ​​together. The display device can be an LED (Light Emitting Diode panel) display screen. The above are merely preferred embodiments of this application and are not intended to limit the 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.
