Optical Properties of the Retro-reflective Polarization Film Fabricated by Stacking Anisotropic and Isotropic Materials
As Liquid Crystal Display (LCD) market with ultra-high definition is growing, high contrast ratio and high light efficiency are required. The anisotropic reflective film can improve light efficiency of the back light unit of LCD TV due to the retro-reflective polarization film, which is named as the double brightness enhanced film fabricated by stacking an optically anisotropic and isotropic layer. We have calculated the transmittance, the reflectance and the polarization degree of the proposed film with respect to the layer number. We also demonstrate the optical performance of the anisotropic reflective film.
