A Liquid Crystal Device and Method Thereof

KSU-324

Abstract: This invention provides a liquid crystal device and method.  After applying an electrical voltage on a liquid crystal to induce a reorientation of the liquid crystal, this invention involves a second electrical voltage with proper polarity to be applied to the liquid crystal to assist in the relaxation of the reorientation that was induced by the earlier electrical voltage.  Therefore the "switch-off" phase of the LC can be hastened or shortened – and the device can exhibit better performance through faster responses. 

Applications: This invention assists faster switching for all electrically driven liquid crystal devices such as liquid crystal (LC) displays, LC shutters, LC lenses, spatial light modulators, telecommunication devices, tunable filters, and beam steering devices among others..

Advantages: Active control of the switch-off phase of liquid crystal devices, allowing for faster response times.
