Detailed Description

The brim of a hat structure that current display screen set up makes face guard structural integrity relatively poor, has the china ink color inconsistent, influences the problem of impression. Therefore, the present invention provides a new solution, and for a clearer representation, the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1-4, a novel LED plastic mask comprises a mask body 10, wherein the mask body 10 is installed on a PCB (printed circuit board) 20 of an LED display screen, and after the mask body 10 is installed, a layer of silica gel is poured between the mask body 10 and the PCB 20 for dust and water prevention.

The LED lamp tube mask is characterized in that a plurality of LED lamp tubes 21 are arranged on the PCB 20, the thickness of the mask body 10 is larger than that of the LED lamp tubes 21, and a plurality of lamp holes 11 corresponding to the LED lamp tubes 21 are formed in the mask body 10. The inner walls of the lamp holes 11 are inclined surfaces 111, the inclined surfaces 111 are inclined downwards from the front surface of the mask body 10 to the rear surface of the mask body 10, and the size of the opening of the lamp hole 11 is gradually reduced from the front surface of the mask body 10 to the rear surface of the mask body 10.

In this embodiment the front surface of face guard body is the planarization, can make the whole ink color of face guard unanimous, improves the impression.

The lamp holes 11 are arranged along the horizontal direction and the vertical direction, and the intervals of the lamp holes 11 in the horizontal direction are equal to those in the vertical direction. The whole is arranged in a matrix form.
