In this paper we present a new possibility to obtain analogue grey level in surface stabilized ferroelectric liquid crystal displays (SSFLCD). Our simulation results show that the switching time under certain applied voltage can be changed by varying the surface anchoring coefficient. Consequently, the percentage of the FLC switching area according to the applied data voltage can be controlled by a certain distribution of the surface anchoring strength within a single pixel. Since the optical transmission is the integral of the whole pixel, by applying appropriate addressing schemes, analogue grey levels become possible. This is confirmed by our simulation and experiment results.

Abstract
In this paper we present a new possibility to obtain analogue grey level in surface stabilized ferroelectric liquid crystal displays (SSFLCD). Our simulation results show that the switching time under certain applied voltage can be changed by varying the surface anchoring coefficient. Consequently, the percentage of the FLC switching area according to the applied data voltage can be controlled by a certain distribution of the surface anchoring strength within a single pixel. Since the optical transmission is the integral of the whole pixel, by applying appropriate addressing schemes, analogue grey levels become possible. This is confirmed by our simulation and experiment results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
