Abstract

A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.
