Method used

The ground side of the four-sided liquid crystal display module is coated with matte UV glue. After curing by the ultraviolet lamp, a matte appearance effect is formed and a good bond is formed to reduce the risk of falling off. At the same time, the glue is closely combined with the upper polarizer to avoid gaps.

Benefits of technology

It effectively reduces the risk of decorative strips falling off, improves the flatness and aesthetics of the product surface, and ensures the realization of the four-sided effect.
