Abstract
Disclosed herein is an apparatus for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly. The assembly includes a liquid crystal display having a back side and a front side, a polarization-maintaining, light-diffusing layer adjacent to the front side of the liquid crystal display, and a front light-polarizing layer disposed adjacent to the polarization-maintaining, light-diffusing layer. A method for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly also is disclosed.
