Abstract

A bistable twisted nematic (BTN) LCD exhibits optical bistability, fast response time, high contrast, and wide viewing angle. For high speed operation of a high resolution BTN panel without any cross-talk problem, the drive scheme must be optimized for matrix addressing. In our previous works, we introduced a high speed addressing method and a method for the optimization of the drive scheme for matrix-addressed operation of a BTN LCD. In this work, we introduce the optimization method of drive scheme by using a weighting function and studied dependence of the weighting function of a BTN LCD on elastic constants of liquid crystal.
