Abstract

This paper presents the development of SPICE equivalent circuits for the electrical and optical modelling of Ferroelectric Liquid Crystal (FLC) on silicon devices. An electro-optical model has been evaluated in a previous publication and although it can simulate the optical output from a display cell it does not accurately model the drive current required to switch the FLC material from one state to the other. A new SPICE model which can be used in the design of the CMOS backplane that drives the FLC display has been developed and the results of optimising this model to fit electrical measurement data are presented.
