Louver structure → Anisotropic Diffusion (ADF) Columnar structure → Isotropic Diffusion (IDF)

This unique light diffusion film has a refractive index distribution structure inside the film. By using light efficiently, it is able to contribute to high visibility and energy saving in display devices. The diffuse shape (anisotropic/isotropic) and diffusion angle can be adjusted depening on the purpose.
