Abstract

Liquid crystal (LC) materials possessing the chiral smectic A phase have been designed to yield high induced tilt angels and low response times. The primary objective of our work is to design materials that can provide the optimum tilt angle of 22.5 degrees for applied voltages less than 5V/micrometers , making them CMOS compatible Optical response measurement to illustrate the feasibility of obtaining 256 gray levels are presented. The gray scale capability of the material is visually demonstrated using a 1 X 64 array driven by a dc balanced circuit.
