Quantitative prediction of the modulation behavior of twisted nematic liquid crystal displays based on a simple physical model

A method to perform a predictive search for a given amplitude and phase modulation response in twisted nematic liquid crystal displays is presented. The algorithm is based on a simple physical model that we recently proposed and that considers the effect of liquid-crystal layers located in the vicin...
