Improvement of the electro-optical properties of film-type low twisted nematic liquid crystal displays

We calculated the electro-optical characteristics of FLTN-LCDs using comput er simulation of the dynamic behavior of liquid crystal molecules. Through the numerical calculation, it was clarified that the response time of the F LTN-LCDs is about 3 times faster than that of usual TN-LCDs when the identi cal cell gap is employed. To improve the other electro-optical characterist ics, we determined a twisting angle to be about 60 degrees from the view po int of an inherent colorization and a gray scale capability and then optimi zed the material and design parameters of the FLTN-LCDs for the twisting an gle of 60 degrees. Under the optimized conditions, we were able to obtain F LTN-LCDs with a fast response time, a good gray-scale capability, a negligi ble inherent colorization, a high contrast ratio and a wide viewing angle.
