Modeling and Computer Simulation of the Electrooptic Response of Polymer-Stabilized Ferroelectric Liquid Crystal Cells

Abstract

The dynamical electrooptic (EO) response of mesogenic side-chain polymer-stabilized ferroelectric liquid crystal cells has been investigated based on the continuum theory. From numerical calculations, the transition from the bistable EO response to the monostable EO response for pulse-applied voltages is clearly demonstrated with increasing degree of polymer stabilization, where free energy originating from the polymer stabilization is formulated and adopted. The reduction of the fall time constant is revealed in this transition. These behaviors are shown to be in qualitative agreement with the results of independent experimental measurements.
