The diffusion film is a semi-transparent film with a matte surface and a light diffusion function. It is a thin film material that can improve the uniformity of brightness. Diffusion films are mainly used in LCD backlight modules, flat panel lighting and other fields. Diffusion film is based on polyester (PET) film or polycarbonate (PC) film, and uniform functional coating and anti-blocking coating with uneven structure are made on both surfaces. When light continuously passes through these coatings, the point light source becomes a uniform surface light source due to the diffuse reflection and diffusion of the uneven structure medium. This causes light refraction, reflection and scattering, forming an overall optical diffusion effect. The interlayer structure of the diffusion film is mainly composed of a substrate, a diffusion layer and an anti-adhesion layer.
