Simulation of improved electro-optical properties of film-type low-twist-angle nematic liquid crystal displays

This paper describes the optimum design for film-type low-twist-angle nemat ic liquid crystal displays (FLTN-LCDs) using a computer simulation of the d ynamic behavior of the liquid crystal molecules. The numerical calculation shows that the response time of the FLTN-LCDs is 3 times faster than that o f conventional TN-LCDs. To improve the other electro-optical characteristic s, we determined that the twist angle should be about 60 degrees. then we o ptimized the material and the dt sign parameters of the FLTN-LCDs for that twist angle. Under the optimized conditions. we were able to obtain FLTN-LC Ds with good electro-optical characteristics, such as fast response time, g ood grade-scale capability, high contrast ratio. and wide viewing angle.
