What are the working principles of light guide plate and light guide plate?

Working principle of light guide plate:

By using the optical acrylic plate, the light emitted from the lamp stays on the surface of the optical acrylic plate. When the light hits each light guide spot, the reflected light will spread to all angles, and then it will break the reflection condition and exit from the front of the light guide plate. The light guide plate can emit light uniformly through light guide spots with different densities and sizes. The purpose of the reflector is to reflect the light exposed from the bottom back to the light guide plate to improve the efficiency of light use.

Introduction:

The design principle of light guide plate comes from the LCD screen of notebook computer, which is a high-tech product that transforms line light source into surface light source. Based on optical grade acrylic (PMMA)/PC, the backlight module technology of LCD screen and notebook computer is adopted. Through the high light conductivity of the light guide spot, the light of the light guide plate is refracted into a uniform light state by computer calculation. This product is made by combining spectral analysis principle with digital UV printing technology under the conditions of constant temperature, constant humidity and dust-free. It has the remarkable characteristics of ultra-thin, ultra-bright, uniform light guide, energy saving and environmental protection, no dark area, durability, difficulty in yellowing, simple and quick installation and maintenance.
