[0036] The rear body 1 includes a bottom housing and a plurality of supports 11 fixedly arranged in the bottom housing; the support 11 is used to support the glass 4.

[0037] The LED lamp panel 2 is fixedly arranged in the bottom housing; a top surface of the support 11 is higher than a top surface of the lamp bead 22.

[0038] The LED lamp panel 2 is first installed in the rear body 1, and the support 11 passes through the first through hole 23. Then cover the glass 4 on the support 11, and finally pour glue into the gap between the glass 4 and the side plate 12, and the glue would form an adhesive layer between the glass 4 and the side plate 12. Compared with the prior art, the LED floor tile screen provided by the application has the following benefits: the support 11 of the LED floor tile screen in the application supports the glass 4, which can transmit the pressure on the glass 4 to the rear body 1, thereby preventing the glass 4 from crushing the lamp bead 22, protecting the lamp bead 22, omitting the front body structure normally used in the prior art, saving the cost and further improving the display clarity of the LED floor tile screen. At the same time, the glass 4 is used instead of acrylic transparent panel, which can avoid discoloration under sunlight, improve transparency and clarity, and make the display effect better. The support 11 and adhesive layer 3 are adopted, instead of using screws to fix the glass. In this way, the connection is simpler and firmer, thus avoiding the influence of insufficient strength or sliding caused by the small size of screws. Meanwhile, it plays a waterproof role and avoids damaging the electrical components in the LED floor tile screen.

[0039] In an embodiment, the glass 4 is tempered glass. Tempered glass has the advantages of high strength, large bearing capacity, non-shattering, higher safety and long service life.

The support 11 passes through the first through hole 23 and abuts against the glass 4. The support 11 has a better supporting effect on glass 4, and can also play a role of limiting the position of PCB board 21, which is convenient for processing and installation.

[0041] In an embodiment, the support 11 is a transparent support. The light emitted by lamp bead 22 will not be blocked, so that the black spots on the LED floor tile screen caused by light blocking can be avoided, and the display clarity is improved and the display effect is better.

[0042] In an embodiment, the supports 11 are uniformly distributed on the PCB board 21, the glass 4 is supported more evenly, so as to avoid deformation of the glass 4 caused by excessive local stress, which would crush the lamp bead 22 and affect the display effect of LED floor tile screen. Meanwhile, the PCB board 21 is more stable by the limit of support 11, thus avoiding the PCB board 21 from moving during glue filling.

[0043] In an embodiment, the adhesive layer 3 is a transparent adhesive layer. In this way, the display transparency and clarity of LED floor tile screen are improved, and it is also convenient to check the connection stability between glass 4 and rear body 1.
