Abstract
A fast flexoelectro-optic switching device containing bimesogen-doped and polymer-stabilized vertical standing helix (PSVSH) in a cholesteric liquid crystal. The PSVSH device exhibits a response time of less than 0.7 millisecond, high contrast and negligible hysteresis which is suitable for applications including blur-free displays, field-sequential color displays and active optical elements.
