[0029] Example 1: As Figures 1 to 7 As shown, this embodiment provides a waterproof transparent screen module with equal-pitch spacing, including a face mask 1, an LED circuit board 2, and a bottom shell 3. The bottom shell 3 is disposed on the back of the face mask 1, and the LED circuit board 2 is disposed between the face mask 1 and the bottom shell 3. A first light-transmitting hole 11 is provided on the face mask 1, a second light-transmitting hole 21 is provided on the LED circuit board 2, and a third light-transmitting hole 31 is provided on the bottom shell 3. The first light-transmitting hole 11, the second light-transmitting hole 21, and the third light-transmitting hole 31 are arranged in a matrix and are correspondingly positioned. A hollow light-transmitting column 32 is formed by extending along the inner wall of the third light-transmitting hole 31. The light-transmitting column 32 is inserted into the second light-transmitting hole 21. Sealant is poured into the bottom shell 3 to seal the LED circuit board 2. A first buckle 12 is provided on one side of the face mask 1 and the bottom shell 3, and a first fastening position 33 is provided on the other side. The first buckle 12 and the first fastening position 33 are detachably snapped together.

[0030] To enhance the tensile strength of the first buckle, the first buckle position 33 can be thickened, protruding until it reaches the empty space of the other module.

[0031] The waterproof transparent screen module with equal pixel spacing provided in this embodiment displays images at equal intervals without loss of image information and has a good waterproof effect.

[0032] The aforementioned structure is simple, and both the chip side and the lamp side of the LED circuit board 2 are well protected by water. This improves the overall waterproof and dustproof performance of the waterproof transparent screen module, preventing easy damage to the LED circuit board 2 and effectively extending its service life. In particular, the hollow light-transmitting column 32, which extends along the inner wall of the third light-transmitting hole 31, allows for the pouring of sealant into the bottom shell 3, preventing the sealant from overflowing from the second and third light-transmitting holes 21 and 31.

[0033] By setting the first light-transmitting hole 11, the second light-transmitting hole 21, and the third light-transmitting hole 31 in a matrix distribution, the overall wind resistance of the waterproof transparent screen module can be effectively reduced, making the outdoor use and construction of the waterproof transparent screen module safer and avoiding the occurrence of safety accidents.

[0034] Furthermore, by setting the first light-transmitting hole 11, the second light-transmitting hole 21, and the third light-transmitting hole 31 in a matrix distribution, the ventilation and heat dissipation performance of the waterproof transparent screen module can be effectively improved, thereby extending the service life of the waterproof transparent screen module.

[0035] In this embodiment, the mask 1 can ensure the consistency of the ink color of the transparent screen module to a certain extent, and it is fixed to the surface of the LED circuit board 2 to play a certain protective role, preventing the LED circuit board 2 from being easily damaged.

[0036] In this embodiment, a second buckle 13 is provided on the face mask 1. The second buckle 13 is used to detachably engage with the locking position on the bottom shell 3. In particular, a through hole 23 is provided on the LED circuit board 2. The second buckle 13 passes through the through hole 23 and is detachably engaged with the locking position on the bottom shell 3. Its structure is simple and reasonable. Through the engagement between the second buckle 13 and the locking position on the bottom shell 3, and in conjunction with the engagement between the first buckle 12 and the first locking position 33, the connection between the face mask 1, the LED circuit board 2 and the bottom shell 3 can be made more stable and reliable, so that the three form a whole.

[0037] Furthermore, a second fastening position 36 is provided on the bottom shell 3. Adjacent transparent screen modules are assembled together by cross-fastening with the second fastening position 36. The second fastening position 36 of the first transparent screen module and the second fastening position 36 of the second transparent screen module are connected accordingly. In particular, each transparent screen module has 6 pairs of opposite second fastening positions 36 that restrain each other, thereby ensuring that the seam of the two transparent screen modules is on the same line, thus ensuring the flatness of the transparent screen modules after splicing.

[0038] Furthermore, LED light holes 14 are provided on the mask 1 between adjacent first light-transmitting holes 11, and LED beads 22 on the LED circuit board 2 are located in the corresponding LED light holes 14. In particular, the first light-transmitting holes 11, the second light-transmitting holes 21 and the third light-transmitting holes 31 are arranged in a matrix and their positions are corresponding. The LED beads 22 are also arranged in a matrix and evenly distributed between adjacent first light-transmitting holes 11. In this way, while maintaining image integrity and information integrity, the overall weight of the product can be effectively reduced. The pixels are connected in a matrix, making the structure stronger and less prone to breakage or bending.

[0039] Furthermore, a plurality of storage holes 34 are provided on the bottom shell 3. The LED circuit board 2 is embedded in the bottom shell 3, and the chip on the back of the LED circuit board 2 is housed in the storage holes 34. When applying the potting adhesive for waterproofing, the chip on the back of the LED circuit board 2 is pre-housed in the storage holes 34. Only the front of the LED circuit board 2 needs to be potted, and a closed perimeter is formed with the light-transmitting column 32. After potting, the front and back of the LED circuit board 2 can be completely waterproofed.

[0040] In this embodiment, crisscrossing reinforcing ribs 35 are provided on the back of the bottom shell 3. The reinforcing ribs 35 are hidden in the area outside the third light-transmitting hole. The structure is simple. Without affecting the overall light transmittance of the transparent screen module, the reinforcing ribs 35 help to improve the overall structural strength of the transparent screen module.

[0041] Preferably, the back of the third light-transmitting hole 31 is flared, meaning the third light-transmitting hole 31 of the bottom shell 3 is drafted from the outside with a draft angle. This makes it resemble a flared hole when viewed from the back of the transparent screen module, thereby increasing the light transmittance and improving the transparency of the transparent screen module. Similarly, in applications using acoustically transparent cinema screens, it helps to increase sound transmission.

[0042] Furthermore, a module interface hole 37 is provided on the bottom shell 3, and a hollow module interface portion 38 extends along the inner wall of the module interface hole 37. The electrical connection structure between the LED circuit board 2 and the external adapter module is located within the module interface portion 38. This structure is simple and rationally designed, facilitating the electrical connection between the LED circuit board 2 and the external adapter module and improving the convenience of connection between product components. In addition, waterproofing can be achieved after potting, thus improving the product's waterproof performance.

[0043] The waterproof transparent screen module with equal-pitch spacing provided in this embodiment mainly includes a waterproof base shell 3, an LED circuit board 2, and a face mask 1.

[0044] First, a special waterproof base shell 3 is custom-made, with a third light-transmitting hole 31 for the matrix, and a surrounding edge, i.e. a light-transmitting column 32, is formed along the inner wall of the third light-transmitting hole 31. The LED circuit board 2 is then inserted into the base shell 3, and the light-transmitting column 32 passes through the second light-transmitting hole 21 of the LED circuit board 2 to form a surrounding edge with glue.

[0045] Secondly, after filling the bottom shell 3 with glue and letting the sealant dry, both sides of the LED circuit board 2 will be protected.

[0046] Then, install the face mask 1 to ensure the consistency of the ink color of the waterproof transparent screen module; the face mask 1 is partially fixed to the bottom shell 3 by a clever method, that is, by the fastening of the first buckle 12 and the first buckle position 33, and the fastening between the second buckle 13 and the bottom shell 3, the face mask 1, the LED circuit board 2 and the bottom shell 3 are fixed together, thus ensuring the reliable fixation of the face mask 1, and also making the assembled structure stronger and less prone to bending, warping and deformation.

[0047] In this embodiment, a ramp 360 is provided on the second buckle 36. The second buckle 13 is connected to the second buckle 36 by the ramp 360. Especially when two modules are spliced, the splice seam can be intuitively seen, and the flatness is in one plane, making it difficult to see the flat seam. In addition, it is easy to remove when the module is disassembled individually.

[0048] 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.
