Description

Technical Field

[0001] The invention belongs to the technical field of display screens, and more specifically, relates to an LED floor tile display screen. Background Art

[0002] LED floor tile display screen has the advantages of flexible installation, good load-bearing performance, easy maintenance, high contrast, uniform grayscale, good consistency, etc. It is widely used in stages, catwalks, booths, bars, nightclubs, broadcasting halls, conference rooms, multimedia classrooms and other places or occasions.

[0003] LED floor tile display screen is a display screen laid on the floor, which can display the required image more clearly and accurately. The LED floor tile display screen on the market is formed by covering the conventional LED module (composed of a rear body, a front body, and an LED light board) with an acrylic transparent panel; first, a fixing screw hole is reserved on the LED module, then the acrylic transparent panel is covered on the top surface of the LED module, and finally the acrylic transparent panel is fixed to the LED module by screws. However, the existing LED floor tile display screen still has the following disadvantages: 1. The transparency of the acrylic transparent panel is poor, and it is easy to change color under the irradiation of sunlight intensity, affecting the display effect; 2. The screws on the acrylic transparent panel are obvious. When using the floor tile screen, there will be a blind spot of light where the screws or bolts are installed, which will be displayed as a black spot without an image on the floor tile screen, seriously affecting the display effect of the floor tile screen; 3. Since the screws are designed in the center of the four lights, the small distance between the light points will inevitably require small screws, resulting in insufficient screw strength and easy slippage. Summary of the invention

[0004] The purpose of the present invention is to provide an LED floor tile display screen to solve the technical problem of poor display effect of the LED floor tile display screen in the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide an LED floor tile display screen, comprising a rear body and an LED light board fixedly mounted on the rear body; the LED light board comprises a PCB board and a plurality of lamp beads fixedly mounted on the PCB board; and further comprises a glass covering the LED light board and an adhesive layer for sealing and bonding the glass and the rear body;

[0006] The rear body comprises a bottom shell and a plurality of support bodies fixed in the bottom shell; the support bodies are used to support the glass;

[0007] The LED lamp board is fixed in the bottom shell; the top surface of the support body is higher than the top surface of the lamp bead.

[0008] Furthermore, a first through hole is provided on the PCB board, and the first through hole avoids the lamp bead; the support body passes through the first through hole and abuts against the glass.
