Two-frequency addressing of a cholesteric texture change electro-optical effect

The Grandjean to focal conic texture change of cholesteric substances is examined by utilizing a two-frequency addressable cholesteric material. Conditions for multiplexed addressing of this brilliant electro-optical effect are studied. The storage property makes it suitable for application in displays of high information content. However, relatively high driving voltages, temperature sensitivity of driving conditions, and relatively slow response indicate possible indoor applications in displaying slowly changing information.
