摘要：
Dynamics of a nematic liquid crystal in external switching field was examined for various initial states of electrostatic equilibrium. Two-step electric field was applied to study the switching dynamics from the first step equilibrium at Eo to the second step equilibrium at Et the results of which could be explained by a change in effective rotational viscosity and the Erickson-Leslie theory. Extension to a gray scale switching process is a possible application.
