In some embodiments, the LED display module 100 is provided with two wireless communication units 150 disposed on two opposite sidewalls of the LED display module 100, and two wireless communication units 150 are disposed opposite to each other. Meanwhile, the two wireless communication assemblies 150 communicate within a preset distance, and the preset distance is smaller than any one of the length and the width of the LED lamp panel 101, so that the two wireless communication assemblies 150 in the same LED display module 100 cannot communicate with each other. Therefore, the wireless communication component 150 can only communicate with another adjacent LED display module 100, thereby realizing the cascade connection of different LED display modules 100. For example, in a specific embodiment, the two wireless communication components 150 can only establish a stable data transmission channel within a range of 0cm to 15cm, so that after the light and thin LED display box 10 is spliced to form an LED display screen, the adjacent LED display modules 100 are cascaded with each other, thereby avoiding interference between the adjacent LED display modules 100, and meanwhile, short-distance communication can also greatly reduce electromagnetic interference, which is beneficial to EMC design.

the free end of the upper shell 113 is provided with a connecting through hole, and the working cavity is communicated with the outside through the cavity of the plug socket and the connecting through hole; the upper shell 113 is trumpet-shaped, and the diameter of the inner wall of the upper shell 113 is smaller the closer to the free end provided with the through hole is;

the balls 114 are accommodated in the accommodating holes, and the balls 114 are abutted against the inner wall of the upper shell 113; the balls 114 are at least partially exposed out of the accommodating holes and enter the working cavity of the inner cylinder 112;

a connecting column 210 is correspondingly arranged on the box body frame 200; when the LED display module 100 is fixedly connected to the box frame 200, the connecting column 210 is inserted into the connecting through hole and extends into the working cavity of the inner cylinder 112, and the connecting column 210 abuts against the balls 114.

Under the pushing force exerted by the elastic member 115, the inner cylinder 112 is pressed toward the free end of the upper shell 113, and the distance between the upper shell 113 and the inner cylinder 112 is reduced because the upper shell 113 gradually shrinks toward the connecting through hole. The balls 114 disposed in the receiving holes of the inner cylinder 112 are pressed by the upper shell 113, and exert a considerable force on the connecting column 210 extending into the working cavity of the inner cylinder 112, so as to fix the connecting column 210 on the socket 110, thereby realizing the fixed connection between the LED display module 100 and the box frame 200.

On the LED display module 100, a plurality of sockets 110 may be disposed. For example, the sockets 110 may be respectively disposed at four corners of the LED display module 100. It is understood that the socket 110 may be disposed on the box frame 200, and the connecting column 210 may be disposed on the LED display module 100.

The elastic member 115 may be hollow to facilitate the connection post 210 to extend into the working chamber of the inner barrel 112. The elastic member 115 may be a spring, or may be other devices or structures capable of providing elastic force. The connecting post 210 may extend partially into the hollow interior of the resilient member 115 when it extends into the working chamber of the inner barrel 112.

During the concatenation, the connection tapered end 273 of concatenation hasp 270 on a box frame 200 can insert the concatenation tapered end on the adjacent box frame in, according to the rotatory handheld piece 272 of certain direction, can be so that the screw thread post 271 removes towards the direction of keeping away from the adjacent box frame, drives and connects tapered end 273 syntropy and remove, until connecting the curb plate of tapered end 273 butt at adjacent box frame, realizes the fixed connection between the adjacent box frame. When unlocked, the hand piece 272 is rotated in the reverse direction.

In order to facilitate positioning between adjacent LED display boxes during splicing, positioning columns and positioning holes may be further disposed on the side plates 201 of the box frame 200.

Another embodiment of the present application further provides an LED display screen, as shown in fig. 16, which includes a plurality of LED display boxes 10, the plurality of LED display boxes 10 are spliced together to form a display screen, and the LED display box 10 is a light and thin LED display box according to any one of the foregoing embodiments. The LED display screen may further include a splicing frame, and the LED display box 10 may be fixed on the splicing frame.

By adopting the light and thin LED display box body provided by the embodiment, the light and thin LED display screen can be realized, the bearing requirement on the installation environment is reduced, and the applicable places of the LED display screen are effectively expanded.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
