What is a light guide plate in an LCD screen?

The light guide plate mainly uses some optical grade acrylic/PC sheets, and then uses high-tech materials with a very high reflectivity and no light absorption, and then uses laser engraving and V-shaped cross grid on the bottom surface of the optical grade acrylic sheet. The engraving and UV screen printing technology are printed on the light guide points.

The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light enters each light guide point, the reflected light will generally diffuse to all angles, and then the reflection conditions will be destroyed. The light guide plate is emitted from the front. Through various light guide points of different density and size, the light guide plate can be made to emit light uniformly. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the light guide plate to improve the use efficiency of light; under the condition of the same area of luminous brightness, the luminous efficiency is high and the power consumption is low. The single-sided microstructure array light guide plate generally adopts the manufacturing process of extrusion molding.
