What is an optical film?

The optical film is processed on the basis of the optical base film. 

The optical base film is mainly made of polyester chips as the main raw material. Because it needs to meet the performance requirements of high light transmittance, low haze, and high brightness, the optical base film is made of polyester The field with the highest technical barriers in the thin film industry. Domestic optical films for backlight modules mainly include reflective films, brightness enhancement films, and diffusion films. The optical base film for polarizer mainly includes TAC film (support layer), PVA film (polarizing layer), AG film (anti-glare layer), protective layer, WVDLC optical compensation film, etc. Generally speaking, there are mainly five types of optical films, namely, general prism film, multi-function prism film, polarizer and diffuser, etc. Each type of optical film also has different characteristics and has its own market.
