Description

Technical Field

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

[0002] The outdoor application market for displays is vast, with widespread use in storefronts, outdoor advertising, public information displays, stage performances, and other fields. Because outdoor display products have larger screen sizes, they are typically assembled from multiple modules, and each module needs to be waterproof to adapt to outdoor environments.

[0003] In existing technologies, the waterproof performance of modules is poor. When the module's outer casing becomes loose or damaged, moisture can easily penetrate the module, causing corrosion and failure of the internal circuit interfaces, resulting in short circuits or open circuits, and ultimately causing the module to malfunction and the display to fail. Therefore, the quality of the module's waterproof performance directly determines the lifespan of both the module and the display screen. Utility Model Content

[0004] In view of this, this application provides a display module and display screen that can improve waterproof performance.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A display module includes a bracket, a lamp panel, and an adapter plate. The lamp panel and the adapter plate are connected to the same side of the bracket. The lamp panel covers the adapter plate and is communicatively connected to the adapter plate.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-8 As shown, this application embodiment provides a display module, including a bracket 1 and a light panel 2. The bracket 1 is configured as a strip structure to support the light panels 2. Multiple light panels 2 are provided, all connected to the same side of the bracket 1, for displaying images. Here, the number of light panels 2 can be two or three. Arranging multiple light panels 2 sequentially along the length of the bracket 1 reduces the length of a single light panel 2, which is beneficial for processing the light panels 2, improves substrate utilization, and saves costs.

[0033] Specifically, two light panels 2 are provided and arranged along the length of the light panel 2. For example, a single light panel 2 is set to 250*125 square millimeters. In this way, the aspect ratio of the display module can be larger, thereby solving the problem of vertical bright and dark lines on larger-sized displays.

[0034] It should be noted that, due to the limitations of the processing equipment's stroke and the issue that larger sizes result in greater precision errors, assembling multiple light panels 2 onto a single bracket 1 can improve the yield rate and reduce processing difficulty. Of course, when the processing equipment is in operation, the number of light panels 2 can also be set to one, meaning the display module is processed from one light panel 2 and one bracket 1.

[0035] In this design, a converter plate 3 is mounted on the bracket 1 for external power and signal input to the lamp panel 2. The converter plate 3 is positioned between the bracket 1 and the lamp panel 2, with the lamp panel 2 covering the converter plate 3. Specifically, the converter plate 3 is located in the middle of the bracket 1. The converter plate 3 has opposing first and second sides. The first side of the converter plate 3 is closer to the bracket 1, and the second side is closer to the lamp panel 2. The first side of the converter plate 3 has a main interface 34, and the second side has multiple sub-interfaces. Due to the circuit structure on the converter plate 3, the main interface 34 is connected to the multiple sub-interfaces. The main interface 34 is plugged into an external structure, and the multiple sub-interfaces are connected to multiple lamp panels 2 respectively. Thus, the converter plate 3 enables the conversion of power and signals, allowing multiple lamp panels 2 to display according to the signals input from the electrical box.

[0036] In the specific design, the adapter board 3 has multiple interfaces, including signal interfaces and power supply interfaces. The number of signal interfaces and power supply interfaces can be set to one and connect simultaneously to multiple lamp boards 2, or multiple interfaces can be set and connected one-to-one to multiple lamp boards 2. Each lamp board 2 is connected to at least one signal interface and one power supply interface to achieve its own power supply and signal transmission.

[0037] like Figure 3 As shown, a potting groove is provided on the side of the bracket 1 near the lamp board 2. The potting groove contains an adapter plate 3 and sealant. The sealant covers the adapter plate 3, sealing it within the potting groove. Here, the adapter plate 3 is fixed to the bracket 1 with screws. Being exposed to the outside air, it is prone to water ingress and corrosion damage. This solution, by using potting sealant to seal the adapter plate 3 within the potting groove, prevents the adapter plate 3 from contacting the outside air, thus extending its service life and improving structural stability and reliability. Furthermore, because the adapter plate 3 is covered with sealant, the circuitry and components on it have good sealing and waterproofing properties. Even if the display module's outer casing becomes loose or damaged, external moisture entering the structure will not corrode the interfaces on the adapter plate 3, further extending the lifespan of the display module.

[0038] In some embodiments, the back side of the light panel 2 is coated with a waterproof coating. This waterproof coating covers the components of the light panel 2, thereby achieving waterproofing of the light panel 2 itself, which is beneficial for outdoor use. Alternatively, a waterproof coating can also be applied to the edges of the light panel 2, meaning the waterproof coating simultaneously covers both the back side and the edges of the light panel 2, further enhancing the waterproof effect. Here, the waterproof coating can be a UV conformal adhesive.

[0039] like Figure 1As shown, the bracket 1 has multiple perforated holes 11, which are evenly distributed and penetrate the bracket 1 to expose the waterproof coating on the lamp panel 2, thereby improving the heat dissipation of the lamp panel 2. For example, the perforated holes 11 can be strip-shaped and extend along the length of the bracket 1; specifically, there are 16 perforated holes 11. Since the lamp panel 2 itself is waterproof, there is no need for the bracket 1 and lamp panel 2 to work together for waterproofing; the bracket 1 only serves to support and protect the lamp panel 2. In this way, by setting perforated holes 11 on the bracket 1, the heat inside the lamp panel 2 and the bracket 1 can be directly convectioned to the outside, improving the heat dissipation effect and waterproof reliability. At the same time, it can also reduce equipment investment costs and shorten the development cycle of manufacturing processes, and the overall weight of the display module is lighter, making it easier to install and transport.

[0040] A pull ring 13 is provided on the side of the bracket 1 away from the light panel 2. When handling and installing the display module, the pull ring 13 can drive the bracket 1 to move, which is beneficial for position calibration, improving the accuracy of assembly and reducing the difficulty of work.

[0041] For a display module with multiple LED panels 2, the distance between two adjacent pixels on two adjacent LED panels 2 is m. These two pixels represent the center-to-center distance between two light-emitting chips located on either side of the seam between the two adjacent LED panels 2. m is the pixel spacing at the seam between the two adjacent LED panels 2. The distance between two adjacent pixels on the same LED panel 2 is n. These two pixels represent the center-to-center distance between two adjacent light-emitting chips on the same LED panel 2. n is the pixel spacing on the LED panel. The two pixels m and n satisfy -3% ≤ (mn) / n ≤ 3%, meaning the difference between m and n is less than or equal to 3% of the value of n, to ensure that the values ​​of m and n are close.

[0042] In the specific design, when the spacing n = 1.95 between two adjacent pixels on the same light board 2 (i.e., when the pixel spacing on light board 2 is set to 1.95), the spacing m between two adjacent pixels on two separate light boards is m = 1.95 ± 1.95 * 3%, meaning the value of m ranges from 1.8915 to 2.0085 millimeters. This ensures that no bright or dark lines are generated at the seam between two adjacent light boards.

[0043] Bright and dark lines on the screen are caused by minute errors in pixel pitch. For example, if the spacing between the LEDs at the splicing seam is too large, the brightness will decrease, resulting in dark lines; conversely, if the spacing is too small, the brightness will increase, resulting in bright lines. By controlling the difference between m and n to within 3%, bright and dark lines can be eliminated at the splicing seam of the display module, resulting in better display quality and an improved user experience.

[0044] During processing, the position of the light-emitting chips on the lamp board 2 can be adjusted, as can the spacing between two adjacent lamp boards 2, to ensure that the point spacing at the splicing seam of two adjacent lamp boards 2 meets the aforementioned requirements. For example, during processing, a specialized jig can be used to splice multiple lamp boards 2 onto the same bracket 1, which can effectively control the gap between the splicing seams of two adjacent lamp boards 2. After assembly, the splicing seams are checked for bright or dark lines. If bright or dark lines are found, the process is repeated, thus ensuring that the produced display module is free of bright or dark lines. In this way, when multiple display modules are assembled on the support bracket, no bright or dark lines will be generated between two adjacent lamp boards 2 on the display module; only the splicing seam between two adjacent display modules will be visible due to assembly errors.

[0045] like Figure 1-4 As shown, in the first embodiment, the signal interface on the adapter board 3 is equipped with a first wireless module 31, and the lamp board 2 is equipped with a second wireless module 21. The first wireless module 31 and the second wireless module 21 are communicatively connected to enable communication between the lamp board 2 and the signal interface. Specifically, the first wireless module 31 and the second wireless module 21 are positioned opposite each other, and when the lamp board 2 is connected to the bracket 1, the first wireless module 31 and the second wireless module 21 are positioned close together. This wireless connection for signal transmission simplifies the assembly process, reduces the amount of wiring used, and saves costs.

[0046] like Figure 3 , 4 As shown, the power supply interface is provided with an elastic conductive element 32 and an annular seal 33. The annular seal 33 is arranged around the outer periphery of the elastic conductive element 32. The lamp board 2 is provided with a conductive sheet 22, and the conductive sheet 22 and the elastic conductive element 32 are positioned opposite each other. When the lamp board 2 is connected to the bracket 1, the elastic conductive element 32 abuts against the conductive sheet 22 to realize the electrical connection between the lamp board 2 and the power supply interface. At the same time, the annular seal 33 abuts against the lamp board 2 and surrounds the outer periphery of the conductive sheet 22. In this way, the annular seal 33 abuts between the lamp board 2 and the bracket 1, which can seal the inner elastic conductive element 32 and the conductive sheet 22, which is beneficial to improving the safety and stability of the power supply connection.

[0047] Specifically, the elastic conductive element 32 is set as a spring seat, the annular sealing element 33 is set as a sealing sleeve, and the conductive sheet 22 is set as a copper sheet. The structure is simple and easy to process.

[0048] It should be noted that, in the combination of sealant and waterproof coating, the first wireless module 31 is mounted on the adapter plate 3, and the sealant covers and seals both the first wireless module 31 and the adapter plate 3. The second wireless module 21 is mounted on the back side of the lamp board 2, and the waterproof coating covers both the second wireless module 21 and the back side of the lamp board 2. Since the elastic conductive element 32 needs to contact the conductive sheet 22, under the action of the annular sealant 33, the sealant does not cover the elastic conductive element 32, and the waterproof coating does not cover the conductive sheet 22.

[0049] like Figure 5-8 As shown, in the second embodiment, the lamp board 2 and the adapter board 3 are connected by a connecting cable, meaning both the signal interface and the power supply interface are connected to the adapter board 3 via the connecting cable. There can be one connecting cable, which can provide both power and signal transmission; or there can be multiple connecting cables, each providing both power and signal transmission. At least one end of the connecting cable is equipped with a waterproof connector assembly 6, allowing the connecting cable to connect to the lamp board 2 or the adapter board 3. This waterproof connector assembly 6 facilitates the assembly and disassembly of the lamp board 2 and the adapter board 3 for maintenance; it also improves the waterproof performance of the internal wiring, preventing external moisture from affecting the signal and power transmission on the lamp board 2, thereby giving the display module a longer service life and greater stability.

[0050] In the preferred embodiment, a waterproof connector assembly 6 is provided on the side of the lamp panel 2 near the bracket 1. The waterproof connector assembly 6 is communicatively connected to the signal interface via a first connecting line 7 and electrically connected to the power supply interface via a second connecting line 8. Multiple configurations exist for the lamp panel 2; here, two lamp panels are used, and two waterproof connector assemblies 6 are also used. The two waterproof connector assemblies 6 are respectively located in the middle area of ​​the two lamp panels 2, and are symmetrically arranged on both sides of the adapter plate 3. This improves the structural balance and stability. The first connecting line 7 and the second connecting line 8 are the connecting lines mentioned above.

[0051] The waterproof connector assembly 6 includes a first connector 61 and a second connector 62. The first connector 61 is disposed on the lamp panel 2. When the first connector 61 and the second connector 62 are inserted, the second connector 62 wraps around the first connector 61 and forms a sealing structure on the outer periphery of the first connector 61. In this way, the sealing and waterproofing between the first connector 61 and the second connector 62 can be achieved through the insertion of the first connector 61 and the second connector 62. The structure is simple and easy to install.

[0052] In a specific embodiment, the sealing structure may include a sealing ring disposed between the outer wall of the first connector 61 and the inner wall of the second connector 62 to seal the connection between the first connector 61 and the second connector 62. The sealing structure may also include a sealing gasket disposed between the end face of the second connector 62 and the lamp panel 2. When the first connector 61 and the second connector 62 are connected, the sealing gasket is clamped between the second connector 62 and the lamp panel 2.

[0053] like Figure 6 As shown, the sealing structure includes a sealing ring 63, which is sleeved on the outer periphery of the first connector 61, and the outer wall of the sealing ring 63 is provided with sealing grooves. When the first connector 61 and the second connector 62 are connected, the sealing ring 63 is clamped between the outer wall of the first connector 61 and the inner wall of the second connector 62.

[0054] In the case of the waterproof coating, the first connector 61 is connected to the lamp panel 2 and exposed outside the waterproof coating. In the case of the perforated hole 11, the waterproof connector assembly 6 is located inside one of the perforated holes 11.

[0055] In some embodiments, when the adapter plate 3 is connected to the bracket 1, the main interface 34 on the adapter plate 3 protrudes from the bracket 1 in a direction away from the lamp plate 2, that is, the adapter plate 3 penetrates the bottom of the potting groove. When multiple display modules are assembled on the support bracket, they can be plugged into the electrical box on the support bracket through the main interface 34, which is beneficial for positioning the display modules and for a more stable and reliable connection.

[0056] The bracket 1 has a waterproof structure on the side away from the light panel 2, surrounding the main interface 34. When the main interface 34 of the adapter plate 3 is plugged into the electrical box, the waterproof structure also plugs into the electrical box. For example, the electrical box has an electrical interface and a waterproof groove. The electrical interface is located in the waterproof groove and plugs into the main interface 34 of the adapter plate 3. At the same time, the waterproof structure is plugged into the waterproof groove of the electrical box. Through the plugging and cooperation of the waterproof structure and the waterproof groove, the electrical interface and the main interface 34 are waterproofed. In this way, the waterproof structure improves the stability and reliability of the connection between the display module and the electrical box.

[0057] In some preferred embodiments, the waterproof structure includes an annular protrusion 12 and a waterproof rubber ring 4. The annular protrusion 12 is disposed on the bracket 1 and surrounds the outer periphery of the main interface 34. Specifically, the annular protrusion 12 and the bracket 1 are integrally formed. The waterproof rubber ring 4 is fitted around the outer periphery of the annular protrusion 12, and the outer wall of the waterproof rubber ring 4 is provided with waterproof texture. When the electrical interface is inserted into the main interface 34 of the adapter plate 3, the outer wall of the waterproof rubber ring 4 abuts against the inner wall of the waterproof groove. Due to the waterproof texture design on the waterproof rubber ring 4, the waterproof sealing performance between the waterproof rubber ring 4 and the waterproof groove can be better improved.

[0058] The waterproof structure also includes a latch 5, which engages with the inner side of the annular protrusion 12 and limits the waterproof rubber ring 4 to the outer periphery of the annular protrusion 12. This design of the latch 5 prevents the waterproof rubber ring 4 from detaching from the annular protrusion 12, facilitating repeated insertion and removal of the display module and electrical box. For example, the latch 5 has an outer edge; when the latch 5 engages with the annular protrusion 12, the outer edge of the latch 5 abuts against the waterproof rubber ring 4, so that the waterproof rubber ring 4 abuts between the bracket 1 and the outer edge of the latch 5.

[0059] In addition, the waterproof rubber ring 4 can also be fixed to the outer periphery of the annular protrusion 12 by adhesive or heat fusion.

[0060] like Figure 2 As shown, the annular protrusion 12 has an annular groove on its end face away from the bracket 1. The waterproof rubber ring 4 has an inner edge, which is embedded in the annular groove. When the latch 5 engages with the annular protrusion 12, the outer edge of the latch 5 abuts against the inner edge of the waterproof rubber ring 4, pressing the inner edge of the waterproof rubber ring 4 tightly within the annular groove. In this way, the latch 5 presses the waterproof rubber ring 4 firmly onto the annular protrusion 12, which helps improve the installation stability of the waterproof rubber ring 4.

[0061] This application also provides a display module, including a support bracket and display modules. Multiple display modules are arranged and sequentially assembled on the support bracket. Specifically, the support bracket has multiple mounting positions, and the multiple display modules are mounted one-to-one on the multiple mounting positions and fixed with screws. Here, the number of display modules can be three, four, or five. The display modules are those described in the above embodiment. Because the adapter plate 3 is covered with sealant, the circuitry and components on the adapter plate 3 have good sealing and waterproof properties. When the outer shell of the display module is loose or damaged, external moisture can penetrate into the structure without corroding the interfaces on the adapter plate 3, thus improving the service life of the display module.

[0062] In some preferred designs, the display modules are arranged in a strip shape, with multiple display modules arranged along the width of the display module. For example, four display modules are used, and the length of the display surface formed by the four display modules is the length of a single display module, while the width of the display surface is the sum of the widths of the four display modules. This arrangement allows multiple display modules to be spliced ​​in the same direction, eliminating the need to distinguish between the left and right directions of the display modules, thus improving assembly efficiency. Furthermore, multiple display modules can be arranged vertically, forming only a splicing seam between adjacent display modules. This seam extends horizontally, and the display surface formed by the multiple display modules has no vertical dark lines, which improves the user's visual experience.

[0063] It should be noted that, according to ergonomic research, the human eye's field of vision is a rectangle with a length-to-width ratio of 16:9. This means that vertical seams are more noticeable and easier for the eyes to perceive than horizontal seams. This solution can improve the user's visual experience by eliminating vertical bright and dark lines on the display surface.

[0064] In the specific design, the length of the display module is set to 480-520 mm, and the width is set to 100-150 mm. Preferably, the display module is a strip structure of 500*125 square millimeters. Compared with the existing 250*250 square millimeter square structure, this design not only eliminates vertical bright and dark lines on the display surface but also helps to save costs.

[0065] Understandably, the substrate in the display module is cut from a single motherboard. Compared to a 250*250 square millimeter structure, this motherboard can cut more 500*125 square millimeter strip structures, resulting in less waste material. Therefore, the substrate utilization rate of the display module in this solution is higher, and the cost is lower.
