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.
