At present, the main components of light diffuser plates are transparent resin substrates and a small amount of light diffusers doped therein. The transparent resin substrates here include polycarbonate, polymethyl methacrylate, and polystyrene & PP & PC & PMMA. The manufacturing method of the light diffuser plate is to heat the transparent resin substrate doped with diffusion particles to a high temperature of 210°C to 230°C, extrude it into a continuous flat plate of a preset thickness in a molten state, and harden it into a plate with a polymer component after cooling.
