Q: What is the light guide plate?
Answer: The light guide plate is made of optical grade acrylic/PC sheet, and then the high-tech material with high reflectivity and non-absorbing light is used to print the light guide on the bottom surface of the optical grade acrylic sheet with UV screen printing technology point. The optical grade acrylic sheet is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the light guide plate. Front shot. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the light guide plate, so as to improve the efficiency of light use.

Answer: The main material of the light guide plate is optical acrylic (PMMA) plate, its chemical name is *acrylic *methyl resin, and its specific gravity is 1190kg per cubic meter. Transparent acrylic sheet has high light transmittance, strong expansion and impact ability, and is widely used. The quality of the acrylic sheets produced at present is also different due to different manufacturers and different processes. Especially the recycled boards are cheap, but they are easy to yellow and have poor light transmittance. It is not easy to choose acrylic sheets for the production of light guide plates. Transparent board with a yellowing light transmittance of over 92%-93%.
