Abstract

This paper presents the development of an electrical SPICE model of a Ferroelectric Liquid Crystal (FLC) on silicon microdisplay. Previous work has investigated the use of an electro-optical SPICE model to simulate the optical response of an FLC cell to a given electrical signal. However, the design of the backplane drive scheme for the display also requires an accurate model of the electrical load represented by an FLC cell. The model presented here provides a good fit to electrical measurement results and, in addition, can be combined with elements of the electro-optical model to allow the optical response of the cell to be modelled at the same time. This paper also presents results of charge collection current measurements which highlight the differences in the behavior of the cell when it is switched between positive and negative voltages and then in the other direction.
