Properties

Broad spectrum λ/4 films provide constant retardation (λ/4) to any wavelength. The front diffuser realizes a brighter reflective panel by controlling dispersing characteristics. We have combined those with polarizing films into one single unit.

Structures of inner reflective type LCD

The polarizing film,the retardation film and the front diffuser are combined into one unit.

Wavelength characterristics of board spectrum λ/4 films

Constant retardation (λ/4) is given to any wavelength.Conventional wavelength film shifts the retardation of blue and red lights from λ/4, resulting in deteriorated the contrast.

Optical properties of front diffuser

By controlling the diffusing property, brighter reflective panels can be realized.
