DN609 light diffuser BOPET films are manufactured using optical polyester slices in extremely clean and neat environments, which translates into a superior cleanliness, optical uniformity, optical definition, high transmittance, excellent smoothness, high thermal stability and great coating properties. These BOPET films are primarily used as the base film for LCD diffuser films, which are an important backlight component to an LCD module.
