[0002] The diffuser uses chemical or physical means to utilize the physical phenomena of refraction, reflection and scattering when light encounters two media with different refractive indices (densities) on the way. By adding inorganic or organic light diffusers to PMMA, PC, PS, PP, hips and other substrates, or by arranging an array of micro-feature structures on the surface of the substrate, the light is artificially adjusted to cause the light to refract, reflect and scatter in different directions, thereby changing the light's path and achieving full dispersion of the incident light to produce an optical diffusion effect. There are three types of light diffusers.
