摘要：

A method for the determination of rotational viscosity gamma(1) and pretilt angle theta(o) in twisted nematic liquid crystal cells is proposed. The method is based on the analysis of transient current of a cell excited by a de voltage pulse. The accuracy of gamma(1) and theta(o) values determined by the method is demonstrated by means of numerical calculation of exact basic equations. Experimental results for a ZLI2293 (Merck) cell are presented, and the gamma(1) values obtained are found to be in excellent agreement with values in the literature.
