Light Guide Film

Diffusion film + LGF
Diffusion film, which plays the role of optical diffusion in the product. The light passing through the diffusion layer with PET as the base material will pass through the medium with different refractive index, so that the light will have a lot of refraction, reflection and scattering phenomena, which can correct the light into a uniform surface light source to achieve the optical diffusion effect.
