Description

Technical Field

[0001] This utility model relates to the field of LED rental display technology, and in particular to a waterproof, equal-pitch display module and a semi-transparent rental screen. Background Technology

[0002] Currently, the LED rental screen market is mainly dominated by opaque general rental screens and semi-transparent grid transparent screens. General rental screens have the largest usage, while grid transparent screens have a semi-transparent display effect and can play a special scene effect in stage decoration. Therefore, the usage of grid transparent screens is increasing, and the shipment volume is increasing year by year.

[0003] However, both general rental screens and grid transparent screens have shortcomings, such as:

[0004] The opaque nature of general-purpose rental screens limits their application scenarios and makes them incompatible with the specifications of transparent grid screens. Furthermore, general-purpose rental screens are relatively thick and heavy, posing a significant wind resistance, especially when used outdoors, increasing the risk of accidents and presenting certain safety hazards.

[0005] To ensure transparency and maintain image display ratio, grid-style transparent screens typically remove one row at a time, resulting in significant image information loss and a substantial reduction in display quality. Furthermore, the presence of elongated holes makes the display strips prone to bending, deformation, and breakage upon impact.

[0006] Therefore, improvements to rental screen products are increasingly needed. Utility Model Content

[0028] Example 1: As Figures 1 to 5As shown, this embodiment provides a waterproof, evenly spaced display module for use on rental screens. The display module 1 includes a face mask 11, an LED circuit board 12, and a bottom shell 13. The bottom shell 13 is disposed on the back of the face mask 11, and the LED circuit board 12 is disposed between the face mask 11 and the bottom shell 13. A first light-transmitting hole 110 is provided on the face mask 11, a second light-transmitting hole 120 is provided on the LED circuit board 12, and a third light-transmitting hole 130 is provided on the bottom shell 13. The first light-transmitting hole 110, the second light-transmitting hole 120, and the third light-transmitting hole 130 are connected together. The holes 130 are arranged in a matrix and are correspondingly positioned. A hollow light-transmitting column 131 extends along the inner wall of the third light-transmitting hole 130. The light-transmitting column 131 is inserted into the second light-transmitting hole 120 and protrudes to a position slightly higher than the LED circuit board 12. The first light-transmitting hole 110 on the mask is the third light-transmitting hole 130 that covers the bottom shell 13. LED lamp holes 111 are provided on the mask 11 between adjacent first light-transmitting holes 110. The LED beads 121 on the LED circuit board 12 are located in the corresponding LED lamp holes 111.

[0029] The waterproof, equally spaced pixel display module provided in this embodiment can achieve semi-transparent display, equally spaced image display without loss of image information, and can reduce product wind resistance. Furthermore, the pixels are connected in a matrix, making the structure stronger and less prone to breakage or bending.

[0030] The waterproof, evenly spaced display module provided in this embodiment effectively reduces the overall weight of the product while maintaining image integrity.

[0031] Specifically, a small-volume driver chip specially designed for equal pixel pitch is used on the display circuit board, i.e., the LED circuit board 12, to achieve high transparency and image distortion-free effect. Then, the mask 11, the LED circuit board 12, and the bottom shell 13 are assembled into the display module 1. Finally, the display module 1 is assembled onto the frame 2. Its structure is simple and can meet the requirements of rapid setup and low wind resistance for rental screens.

[0032] In particular, the first light-transmitting hole 110, the second light-transmitting hole 120 and the third light-transmitting hole 130 are arranged in a matrix and their positions correspond to each other. The LED beads 121 are also arranged in a matrix and are evenly distributed between the adjacent first light-transmitting holes 110. In this way, the overall weight of the product can be effectively reduced while maintaining the image without distortion and information loss.

[0033] In addition, by setting the first light-transmitting hole 110, the second light-transmitting hole 120 and the third light-transmitting hole 130 in a matrix distribution, the wind resistance of the display module 1 and the rental screen as a whole can be effectively reduced, making the outdoor use and construction of the rental screen safer and avoiding the occurrence of safety accidents.

[0034] Furthermore, by setting the first light-transmitting hole 110, the second light-transmitting hole 120 and the third light-transmitting hole 130 in a matrix distribution, the ventilation and heat dissipation performance of the rental screen can be effectively improved, thereby extending the service life of the rental screen.

[0035] In this embodiment, the mask 11 can ensure the consistency of the ink color of the display screen to a certain extent, and it is fixed to the surface of the LED circuit board 12 to play a certain protective role, preventing the LED circuit board 12 from being easily damaged.

[0036] Furthermore, a plurality of storage holes 132 are provided on the bottom shell 13, the LED circuit board 12 is embedded in the bottom shell 13, and the chip on the back of the LED circuit board 12 is accommodated in the storage holes 132.

[0037] When applying the potting solution for waterproofing, the chip on the back of the LED circuit board 12 is pre-installed in the storage hole 132. Only the front of the LED circuit board 12 needs to be potted to achieve complete waterproofing for both sides of the LED circuit board 12.

[0038] Furthermore, the LED circuit board 12 is embedded within the bottom shell 13, and sealant is poured into the bottom shell 13 to seal the LED circuit board 12. This simple structure provides excellent waterproof protection for both the chip side and the lamp side of the LED circuit board 12, thereby improving the overall waterproof and dustproof performance of the display module 1, preventing easy damage to the LED circuit board 12, and effectively extending its lifespan. In particular, the hollow light-transmitting column 131 extending along the inner wall of the third light-transmitting hole 130 allows for the pouring of sealant into the bottom shell 13, preventing sealant from overflowing from the second and third light-transmitting holes 120 and 130.

[0039] Example 2: Figures 1 to 7 As shown, this embodiment provides a semi-transparent rental screen, including a frame and several display modules. The display module 1 is detachably mounted on the frame 2, and the display module 1 adopts the display module described in Embodiment 1.

[0040] This embodiment provides a semi-transparent rental screen that can achieve semi-transparent display and reduce product wind resistance.

[0041] Furthermore, the frame 2 is rectangular, with a central connecting rod 21 positioned in the middle. Reinforcing rods 22 are respectively provided on both sides of the central connecting rod 21 and on the frame 2. The display module 1 is detachably connected to the frame 2 and the central connecting rod 21 on both sides, and detachably connected to the reinforcing rods 22 at its middle position. This design is simple and reasonable, resulting in high overall structural strength for the frame 2. The reinforcing rods 22 further enhance the overall structural strength of the connection between the display module 1 and the frame 2, thereby improving product stability and reliability. Furthermore, the frame can be rectangular (1000x500mm), square (500x500mm), or rectangular (500x1000mm). Of course, the specifications of the frame 2 can be adjusted and designed according to actual design needs.

[0042] Furthermore, the frame 2, the central connecting rod 21, and the reinforcing rod 22 are integrally die-cast or assembled from profiles, resulting in a simple structure. The structure of the frame 2 can be selected according to design requirements, thereby meeting diverse production needs.

[0043] In this embodiment, a housing 3 is provided on the back of the central connecting rod 21. A detachable control module, a power module, and an adapter module are provided inside the housing 3. The control module is electrically connected to the power module, the adapter module, and the display module, respectively. Its structure is simple, which facilitates the installation of each module and makes it easy to repair and replace, thereby reducing the user's maintenance costs and improving the user experience.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
