碩士 === 國立交通大學 === 光電工程所 === 88 === We examined a method to evaluate the temperature effects on the dynamics of twisted nematic liquid crystal displays. We investigated on the relation between the temperature and the dynamics of 90° twisted nematic liquid crystal displays and bistable twisted nematic liquid crystal displays. In 90° twisted nematic liquid crystal displays, we examined a simple and good method to estimate the temperature effects on the decay time, rise time and delay time. Besides, in bistable twisted nematic liquid crystal displays, we also evaluated the temperature effects on the transition time of the 2p state in the similar way. In our experimental and computer simulation results, there was an optical jut in the homeotropic to 0°state transition. This jut would be influenced by temperature.
