Abstract:
1. An apparatus for a liquid crystal display, the apparatus comprising: a polarizer film configured to receive light from the liquid crystal display; and an optical polarizer screen configured to filter light for the liquid crystal display, wherein the optical polarizer screen comprises a plurality of grooves, each groove being defined by a first side and a second side, the first side comprising a first polarizer and the second side comprising a second polarizer that differs from the first polarizer, wherein one of the first and second polarizers is transparent to light having a first polarization and reflective to light having a second polarization and the other of the first and second polarizers is transparent to light having the second polarization and reflective to light having the first polarization such that the optical polarizer screen is configured to output a plurality of regions of light of the first polarization and a plurality of regions of light of the second polarization.
