Ferroelectric Liquid Crystal Display (FLCD) ppt

FLCD - Ferroelectric Liquid Crystal Display is a relative of the traditional LCD display that has become ubiquitous in the 32" and under-display market. Traditional LCD displays are usually of the Super Twisted Nematic (STN) variety. The FLCD was introduced by Thorn EMI in 1992. The intervening years have seen development solve initial problems with longevity, temperature sensitivity, and vibration sensitivity.

The FLCD is unique compared to the traditional LCD in that it does not need to have a voltage continuously applied to a pixel in order to keep it off. With an FLCD, a voltage is only necessary for the initial switching. This leads to substantial power savings, on the order of 75%. Another advantage of FLCD is the very rapid response time, about 1000 times faster than a standard LCD. The rapid response is essential to eliminating video anomalies when producing fast-moving video images. They have very wide viewing angles as well, which is quite desirable in a consumer-oriented, large screen display.

FLCDs don't need expensive, active switching electronics, which should reduce costs for a large display. They can use simpler, passive matrix switching systems. Some work has been done on producing time-multiplexed, 3D displays using FLCD technology, and this would require the increased switching speed of an active matrix design.
