Light Diffusion FilmLight Diffusion Film DF series
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.

Composition
Features
Unique light diffusion behavior (anisotropic type diffusion / isotropic type diffusion)
Louver structure → Anisotropic Diffusion (ADF)
Columnar structure → Isotropic Diffusion (IDF)
Conventional light diffusion film
ADF / IDF
Incident light angle for diffusion can be controlled
Excellent uniformity of diffused light
High transparency (non-diffusion area)
Low-backscattering
Maintenance of polarization
Application
Projection screens, Reflective displays, Smart watches, etc.
