Abstract

The invention relates to the field of LED display screens. The invention relates to a mask structure, in particular to an LCD display screen mask structure and a manufacturing process thereof. An outer shell of the LED display screen comprises a pressing plate and a mask. The mask is attached to the upper plane of the pressing plate, a plurality of light transmitting holes are formed in the pressing plate, a plurality of light scattering holes are formed in the mask, the light scattering holes and the light transmitting holes are located on the same axis, and the surface treatment process comprises the following steps that S1, the pressing plate and the mask are subjected to pressing treatment in a precision stamping mode; S2, epoxy resin is filled; and S3, the mask is subjected to pressing treatment in a vacuum closed environment. According to the invention, through multi-line refraction of light, the light is uniformly mixed, and the emitted light has few mixed colors, so that the black and white contrast of the display screen is improved, and the brightness of the light is more uniform.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a mask structure of an LCD display screen and a manufacturing process thereof. Background technique [0002] The LED display screen mask is of great significance for protecting the LED display screen. The existing LED display screen mask is formed by continuous splicing of multiple unit pieces, and pixels are evenly distributed on each unit piece; The splicing is prone to bulging, and the splicing gap is too large after being cold and black lines are easy to see; at the same time, the seam is also particularly obvious after splicing adjacent LED display modules; in addition, because the LED display mask is in production There is chromatic aberration, so continuous splicing in use will easily lead to uneven color on the surface of the LED display; in order to overcome the above difficulties, the existing LED display mask needs to be coated with glue on the back during production...
