Fast switching dual-frequency liquid crystal cells and method for driving the same

摘要

A method for fast switching a dual frequency (FIG. 3) liquid crystal cell is disclosed. The liquid crystal cell has opposed substrates (12) with a dual frequency liquid crystal material (18) disposed therebetween. Each substrate has an electrode that is connected to a power supply (20) that is able to apply different voltage magnitudes at different frequencies. And each substrate (12) has an alignment layer that imparts a high pretilt angle to the liquid crystal material, wherein no application of voltage results in the material exhibiting an initial state. A transition driving pulse (104) of a first magnitude is applied to the material at a first
