by：POLYVA 2022-02-01

The diffusion film is semi-transparent with a matte surface and has a light diffusion function. It is a film material that can promote the uniformity of the brightness of the light. Mainly used in LCD backlight module, flat lighting and other fields. Diffusion film characteristics Light passing through the diffusion layer with PET as the base material will pass through the medium with different refractive index, which makes the light have many phenomena of refraction, reflection and scattering, and can correct the light into a uniform surface light source to achieve optical diffusion Effect. In the backlight structure, it mainly plays the role of correcting the diffusion angle and covering the defects of the LGP, which will increase the light radiation area. The luminous light source can become a secondary light source with larger area, better uniformity and more stable chromaticity after passing through the diffusion film material. It has an excellent covering effect, can be used to replace the diffuser in the direct backlight, and has the advantages of good optical performance and low cost. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide range of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, warm and thoughtful service, and the spirit of assisting partners to achieve their own careers.
