Patent ID: 7289176

Claim:
A liquid crystal display system, comprising: a first substrate with a first substrate electrode; a second substrate substantially parallel to the first substrate, the second substrate including a second substrate electrode; a bistable, cholesteric liquid crystalline material disposed between the first and second substrates; at least two interdigitized electrodes, electrically separated from each other and arranged on the second substrate; and a controller coupled to the first and second substrate electrodes and the interdigitized electrodes, the controller to control a color reflected by the liquid crystal display system by controlling a first voltage on a first lead of at least two interdigitized electrode teeth and a second voltage to a second lead of at least two interdigitized electrode teeth to control a pitch distance of the bistable, cholesteric liquid crystalline material, wherein the pitch distance determines the color reflected by the liquid crystal display system; and controlling a reflection state of the bistable, cholesteric liquid crystalline material by controlling a voltage different between substrate electrodes on the first and second substrate electrodes.
