Effect of diffusion film

Generally, the traditional diffusion film mainly adds chemical particles to the diffusion film base material as scattering particles, while the existing diffusion plate has fine particles dispersed between the finger layers, so the light will be refracted between the two layers when passing through the diffusion layer. When passing through media with different rates, light will undergo a lot of refraction, reflection and scattering at the same time, resulting in the effect of optical diffusion.
