Description

Technical Field

[0001] This utility model belongs to the field of display technology equipment, and in particular relates to a display module and a display screen. Background Technology

[0002] The use of displays in touring concerts and similar events is increasing, the demand for digital displays is becoming more concentrated, and the screens are getting bigger and bigger. In order to reduce the strength requirements of the supporting gantry and reduce transportation costs, the displays need to be as lightweight as possible.

[0003] However, in most current LED display modules, the LED chips are mounted on the front of the LED board, the LED driver IC is mounted on the back of the LEDs, and a bottom shell is then placed on the display module to protect the driver IC and other electronic components. The bottom shell is connected and fixed using screws. This results in a complex structure, heavy weight, and high cost for the display module. Utility Model Content

[0004] The purpose of this application is to provide a display module that addresses the problem of simplifying the structure of the display module and reducing its weight.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a display module is provided, comprising: a lamp board, a mask, a driver IC, and a plurality of LED beads, wherein the lamp board has a first surface, the LED beads are spaced apart on the first surface, and the driver IC is connected to the first surface and is used to drive the LED beads.

[0007] Since both the LED chips and the driver IC are arranged on the first board, the driver IC and LED chips can be protected simultaneously by a cover. This eliminates the need for a separate bottom case on the display module to protect the driver IC, simplifying the structure of the display module and reducing its weight.

[0008] In some embodiments, the mask has light-emitting holes, and multiple light-emitting holes are arranged at intervals. The mask is stacked on the first plate and covers the driver IC. Each of the LEDs is located in each of the light-emitting holes.

[0009] Because light-emitting holes are opened on the mask, and each LED corresponds to a light-emitting hole, the light from the LED can propagate outward through the light-emitting holes.

[0010] In some embodiments, the mask has a clearance groove corresponding to the position of the driver IC, and there is a gap between the driver IC and the mask.

[0011] Because a clearance groove is provided on the mask corresponding to the position of the driver IC, the mask can avoid directly pressing the driver IC, reducing the mechanical stress or heat accumulation caused by contact with the driver IC, and improving the working stability and service life of the driver IC.

[0012] In some embodiments, each of the light-emitting holes has a first protruding strip at its edge, and the first protruding strip is located on the surface of the mask facing away from the lamp plate.

[0013] Because a first protrusion is provided at the edge of the light-emitting aperture, the first protrusion enhances the edge structural strength of the light-emitting aperture, preventing deformation of the aperture due to external forces during transportation or use, and ensuring stable light output from the LED beads. In addition, the first protrusion can also block external dust or foreign objects from entering the light-emitting aperture to a certain extent, improving the environmental adaptability of the display module, while multiple first protrusions increase the surface area of ​​the mask, which is beneficial for heat dissipation.

[0014] In some embodiments, each of the light-emitting holes has a second protruding strip at its edge, the second protruding strip being located on the surface of the mask facing away from the lamp plate, and the light-emitting hole being located between the first protruding strip and the second protruding strip.

[0015] The addition of a second convex strip further strengthens the structural strength protection of the light outlet hole. The first and second convex strips together form a more robust three-dimensional protective frame, which not only improves the overall strength of the mask but also more effectively disperses external impacts, reducing the possibility of damage to the LED beads.

[0016] In some embodiments, along the direction from the lamp panel to the mask, the height of the first protrusion is higher than the height of the lamp bead, and the height of the second protrusion is higher than the height of the first protrusion; a plurality of first protrusions are arranged linearly along a first direction and arranged in multiple columns along a second direction, a plurality of second protrusions are arranged linearly along the first direction and arranged in multiple columns along the second direction, and a column of second protrusions is provided between any two adjacent columns of first protrusions, or a column of first protrusions is provided between any two adjacent columns of second protrusions, and the first direction is perpendicular to the second direction.

[0017] Because multiple first and second protrusions are set on the mask, and the second protrusions are taller than the first protrusions, the direction of the light emitted by the LEDs can be controlled. The second protrusions, in conjunction with the lower first protrusions, create a gradient light-blocking and light-guiding effect, thereby improving the contrast of the display module. Furthermore, the higher second protrusions can block some lateral scattered light, reducing the possibility of light spilling into adjacent pixel areas, making bright areas brighter and dark areas darker, enhancing the contrast. At the same time, the staggered height of the first and second protrusions avoids the shadow projection that might be caused by a single-height structure at wide viewing angles. When viewed from the side or from above, the light is more evenly distributed after refraction and reflection by the protrusions of different heights, eliminating shadow areas.

[0018] In some embodiments, the display module further includes a fastener connecting the edge of the light-emitting aperture, the fastener being located on the surface of the mask facing the lamp panel, and the fastener fastening the lamp bead.

[0019] Since each light-emitting hole has at least one fastener at its edge, and the free end of the fastener is fastened to the root of the LED bead, it facilitates the installation and removal of the mask and improves the convenience of installing or removing the display module.

[0020] In some embodiments, the light panel further has a second panel, the first panel being disposed opposite to the second panel, and the display module further includes a fixed base located on the second panel and a handle connected to the fixed base.

[0021] Because a fixed base is set on the second panel and the handle is connected to the fixed base, the display module can be moved by holding the two handles, thereby improving the convenience of using the display module.

[0022] In some embodiments, the display module further includes a waterproof base located on the second panel, the waterproof base being spaced apart from the fixed base.

[0023] Because a waterproof base is installed on the second panel, and a waterproof groove is provided on the waterproof base, it is easy for the waterproof ring to be inserted into the waterproof groove. The cooperation between the waterproof ring and the waterproof base protects the socket connectors of the light board, preventing water from entering the socket connectors and causing short circuits, thereby protecting the electronic components.

[0024] Secondly, a display screen is provided, which includes the display modules, wherein multiple display modules are provided, and the display screen also includes a cabinet frame, wherein each display module is sequentially spliced ​​and connected to the cabinet frame.

[0025] Since the display screen includes the aforementioned display module, there is no need to install a back cover on the display screen to protect the driver IC, which simplifies the structure of the display screen and reduces its weight.

[0026] The beneficial effects of this application are as follows: by arranging both the LED beads and the driver IC on the first board surface, the driver IC can be protected by a cover, eliminating the need for a bottom shell on the display module to protect the driver IC, thus simplifying the structure of the display module and reducing its weight and manufacturing cost.

[0043] Please see Figures 1 to 3 This application provides a display module 100 and a display screen having thereon.

[0044] Please see Figures 1 to 3 The display module 100 includes: a lamp board 11, a mask 12, a driver IC, and a plurality of LED beads 13. The lamp board 11 has a first surface 111, and the LED beads 13 are arranged at intervals on the first surface 111. It can be understood that the LED beads 13 can be arranged at equal intervals on the first surface 111, and arranged in multiple rows and columns. The driver IC is connected to the first surface 111 and is used to drive the LED beads 13. That is, the driver IC can receive external signals (such as display data), convert them into current or voltage signals, and drive the LED beads 13 to light up, adjust their brightness, or switch states.

[0045] Please see Figures 1 to 3 The mask 12 has light-emitting holes 123 that extend through both sides of the mask 12. Multiple light-emitting holes 123 are spaced apart. It is understood that the arrangement of each light-emitting hole 123 is adapted to the arrangement of each LED bead 13. Therefore, when the mask 12 is stacked on the first plate 111 and covers the driver IC, each LED bead 13 is located in its respective light-emitting hole 123. By covering the driver IC with the mask 12, the driver IC can be protected.

[0046] The display module 100 provided in this application embodiment arranges both the LED beads 13 and the driver IC on the first board surface 111, thereby protecting the driver IC through the cover 12. This eliminates the need for a bottom shell on the display module 100 to protect the driver IC, simplifying the structure of the display module 100 and reducing its weight and manufacturing cost.

[0047] Optionally, the lamp bead 13 can be an LED lamp bead.

[0048] Optionally, multiple masks 12 can be provided, and each mask 12 can be spliced ​​on the first plate surface 111 to form a larger mask 12.

[0049] Please see Figures 1 to 3 Optionally, multiple driver ICs can be set at intervals, and the mask 12 covers each driver IC. Each driver IC is used to drive different LED beads 13.

[0050] Please see Figures 1 to 3 In some embodiments, the mask 12 has a clearance groove 125 corresponding to the position of the driving IC, and there is a gap between the driving IC and the mask 12.

[0051] Please see Figures 1 to 3 Optionally, the clearance groove 125 prevents the mask 12 from directly pressing on the driver IC, reducing mechanical stress or heat accumulation caused by contact and improving the working stability and service life of the driver IC. Furthermore, the gap between the mask 12 and the driver IC facilitates heat dissipation for the driver IC, helping to improve the performance stability of the display module 100 under high load operation (such as long-term use during concert tours), thus enhancing product reliability.

[0052] Please see Figures 1 to 3 Optionally, the face mask 12 has multiple clearance grooves 125 on the surface facing the first plate 111, so that the face mask 12 is hollowed out and thinned, which can reduce the weight of the face mask 12.

[0053] Please see Figures 1 to 3 In some embodiments, each of the light-emitting through holes 123 has a first protruding strip 121 protruding from its edge, and the first protruding strip 121 is located on the surface of the mask 12 facing away from the lamp plate 11.

[0054] Please see Figures 1 to 3Optionally, the first protrusion 121 enhances the structural strength of the edge of the light-emitting aperture 123, preventing deformation of the aperture due to external forces during transportation or use, and ensuring stable light output from the LED beads 13. Furthermore, the first protrusion 121 can also, to a certain extent, prevent external dust or foreign objects from entering the light-emitting aperture 123, improving the environmental adaptability of the display module, making it particularly suitable for outdoor applications such as touring concerts. The multiple first protrusions 121 also increase the surface area of ​​the mask 12, which is beneficial for heat dissipation and prevents the display module from overheating.

[0055] Please see Figures 1 to 3 In some embodiments, each of the light-emitting holes 123 has a second protruding strip 122 protruding from its opening edge. The second protruding strip 122 is located on the surface of the mask 12 facing away from the lamp plate 11, and the light-emitting hole 123 is located between the first protruding strip 121 and the second protruding strip 122.

[0056] Optionally, the first protrusion 121 and the second protrusion 122 enhance the structural strength of the light-emitting aperture 123. Together, the first protrusion 121 and the second protrusion 122 form a more robust three-dimensional protective frame, which not only improves the overall strength of the mask 12 but also more effectively disperses external impacts, reducing the possibility of damage to the LED bead 13. Furthermore, the multiple second protrusions 122 increase the surface area of ​​the mask 12, which is beneficial for heat dissipation and prevents the display module from overheating.

[0057] Please see Figures 1 to 3 In some embodiments, along the direction from the lamp plate 11 to the mask 12, the height of the first protrusion 121 is higher than the height of the lamp bead 13, and the height of the second protrusion 122 is higher than the height of the first protrusion 121.

[0058] Please see Figures 1 to 3 Optionally, in this embodiment, the height difference between the first protrusion 121 and the lamp bead 13 is 0.1mm, and the height difference between the second protrusion 122 and the first protrusion 121 is 0.3mm. In other embodiments, the selection can be made according to the actual situation, and no limitation is made here.

[0059] The alternating arrangement of the first convex strip 121 and the second convex strip 122 forms a regular grid-like protective system, improving the overall tensile strength and load-bearing capacity of the mask 12. This enhances the durability of the display module 100 during frequent disassembly, assembly, and transportation, while maintaining the uniformity of the light-emitting aperture 123 to ensure consistent display performance.

[0060] Please see Figures 1 to 3In some embodiments, a plurality of first protrusions 121 are arranged linearly along a first direction and in multiple columns along a second direction, and a plurality of second protrusions 122 are arranged linearly along the first direction and in multiple columns along the second direction. A column of second protrusions 122 is provided between any two adjacent columns of first protrusions 121, or a column of first protrusions 121 is provided between any two adjacent columns of second protrusions 122. The first direction is perpendicular to the second direction. The first direction is denoted as the X direction, and the length direction of the first protrusions 121 and the second protrusions 122 extends along the X direction. The second direction can be the Y direction.

[0061] Optionally, the first protrusions 121 located in the same column are arranged at intervals along the first direction, and the second protrusions 122 located in the same column are arranged at intervals along the first direction.

[0062] Please see Figures 1 to 3 Compared to the first protrusion 121, the second protrusion 122 has a higher height, which allows it to control the direction of light emitted by the LED bead 13. The second protrusion 122, together with the lower first protrusion 121, forms a gradient light-shielding and light-guiding effect, thereby improving the contrast of the display module 100. Moreover, the higher second protrusion 122 can block some side-scattered light, reducing the possibility of light overflowing into adjacent pixel areas, making bright areas brighter and dark areas darker, thus enhancing the contrast between light and dark.

[0063] Meanwhile, the staggered first and second convex strips 121 and 122 avoid shadow projection that may be caused by a single-height structure when viewed from a wide angle. When viewed from the side or from above, the light is more evenly distributed after being refracted and reflected by the convex strips of different heights, thus eliminating shadow areas.

[0064] Please see Figure 4 In some embodiments, the lamp panel 11 also has a second panel 112, with the first panel 111 and the second panel 112 disposed opposite to each other. The display module 100 also includes a fixed base 15 located on the second panel 112 and a handle 16 connected to the fixed base 15.

[0065] Please see Figure 4 Optionally, the fixed base 15 is directly installed on the second panel 112 and is provided with a stable support point by the lamp panel 11. The handle 16 is easy for people to hold, which facilitates the handling and installation of the display module 100 and shortens the disassembly and assembly time.

[0066] Please see Figure 4 Optionally, two fixed bases 15 are arranged at intervals, with the two fixed bases 15 located at opposite ends of the lamp panel 11, and each fixed base 15 is provided with a handle 16. By holding the two handles 16, the display module can be moved, thereby improving the convenience of using the display module.

[0067] Please see Figure 4 In some embodiments, the display module 100 further includes a waterproof base 14 located on the second panel 112, the waterproof base 14 being arranged at a distance from the fixed base 15.

[0068] In this embodiment, a waterproof groove 141 is provided on the waterproof base 14, which facilitates the installation of the waterproof ring within the groove 141. The cooperation between the waterproof ring and the waterproof base protects the female connector of the lamp board 11, preventing water from entering the female connector and causing a short circuit, thereby protecting the electronic components. The waterproof ring can be glued into the waterproof groove 141, and the structural components pressing on the waterproof ring can be fixed to the lamp board 11 with screws to tighten the waterproof ring and enhance the waterproof effect.

[0069] Please see Figure 4 Optionally, two waterproof bases 14 are arranged at intervals, and a fixed base 15 is located between the two waterproof bases 14.

[0070] Please see Figures 1 to 3 In some embodiments, the display module 100 further includes a fastener 124 connecting the edge of the light-emitting hole 123, the fastener 124 being located on the surface of the mask 12 facing the lamp plate 11, and the fastener 124 fastening the lamp bead 13.

[0071] Optionally, each light-emitting hole 123 has at least one fastening part 124 on its edge, and the free end of the fastening part 124 is fastened to the root of the lamp bead 13, thereby facilitating the installation and removal of the mask 12.

[0072] Please see Figures 1 to 4 The present invention also proposes a display screen, which includes a display module 100. The specific structure of the display module 100 is as described in the above embodiments. Since the display screen adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0073] In some embodiments, multiple display modules 100 are provided, and the display screen further includes a cabinet frame, with each display module 100 sequentially spliced ​​and connected to the cabinet frame.

[0074] Optionally, the splicing of multiple display modules 100 enables flexible assembly of large-size displays, meeting the needs of touring concerts for ultra-large screens, while the cabinet frame provides overall support, ensuring that the spliced ​​display has sufficient strength and stability. The display significantly reduces weight while maintaining high transparency and high strength, lowering transportation costs and the load-bearing capacity of the gantry.

[0075] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
