[0002] Light diffusion plate, also known as light uniform plate, is widely used in LED lighting and liquid crystal flat panel display industry, and requires high light diffusivity and high light transmittance. At present, the main components of light diffusion plate are transparent resin substrate and doped with A little light diffusing agent, the transparent resin base material here comprises polycarbonate, polymethyl methacrylate, and polystyrene & PP & PC & PMMA, the manufacturing method of light diffusing plate is that the transparent resin base material doped with diffusing particles is heated to The high temperature of 210°C to 230°C is extruded into a continuous planar sheet with a predetermined thickness in a molten state, and hardened after cooling to form. As a sheet with a polymer composition, the light diffusion sheet will be charged with static electricity after molding. These static electricity will attract foreign objects in the production environment, which often reduces the light transmittance of the light diffusion plate, and cleaning these foreign objects will increase the production cost. Therefore, this technology has defects and needs to be improved
