Optical protection structure of small-spacing LED screen module and manufacturing process

Abstract

The invention relates to an optical protection structure of a small-spacing LED screen module and a manufacturing process. The optical protection structure comprises an SOM module, an optical screen is pasted on the surface of a display screen of the SOM module through optical transparent colloid, the optical screen comprises a plane part and a plurality of cylindrical lens structures, and the cylindrical lens structures are located on the inner side of the optical screen; and the plane part is adjacent to the surface of the SOM module display screen and is positioned on the outer side of the optical screen. The protection performance of the product is greatly improved, meanwhile, the problems of glare, soft image display, fatigue resistance and no ink color consistency of materials can be solved, the investment is small, the life cycle of the small-spacing LED screen module is prolonged, the module is very convenient to maintain, and the module can be spliced without limitation; the surface of the formed LED module has a certain anti-pressure capability so that lamp beads can be prevented from being damaged by an external force, and the formed LED module can be used as a touch type display panel; and the contrast ratio is high, and the surface of the display screen is dustproof and can be wiped and cleaned.

Description

technical field [0001] The invention relates to the technical field of small-pitch LED display, in particular to an optical protection structure and a manufacturing process of a small-pitch LED screen module. Background technique [0002] At present, the display technology of small-pitch LEDs has developed rapidly, accounting for about 56% of the market size of large-screen displays, which is about RMB 18 billion, and still has development potential. Small-pitch LEDs are gradually developing towards high resolution and high reliability, and traditional processes are increasingly challenged by new processes and technologies. Small-pitch LED screens using SMD technology account for about 50% of the small-pitch LED screen. The price is moderate, but the protection performance is poor, and there are many dead lights and caterpillars. It cannot meet the requirements of the current all-in-one machine for touch control. The emergence of COB technology has greatly improved the rel...

AI Technical Summary

Problems solved by technology

[0014] The purpose of the present invention is to provide an optical protection structure and manufacturing process of a small-pitch LED screen module, which greatly improves the protection performance of the product, and at the same time overcomes glare, soft image display, anti-fatigue, and no ink color consistency of the material. The investment is small, which prolongs the life of the small-pitch LED screen module. The maintenance of the module is very convenient and can be spliced ​​without restriction; the surface of the formed LED module has a certain pressure resistance, which can prevent external forces from damaging the lamp beads As a touch-type display panel; moreover, the contrast ratio is high, and the surface of the display screen is dust-proof and can be wiped clean
