FERROELECTRIC LIQUID CRYSTAL TUNABLE FILTERS AND COLOR GENERATION

摘要

Discretely and continuously tunable filters and high contrast light valves employing FLC cells are provided. Discretely tunable filters employ bistable smetic C* FLC cells (LC1, LC2, LC4-LC7). Continuously tunable filters employ smetic A* FLC cells (C, C2, C3, C4). Single or multiple stage filters are provided. Blocking filters useful for color generation are also provided. The FLC filters provided can be temporally multiplexed.
