Abstract

A novel approach to obtain a fast responding STN LCD is described. Response times are reduced to less than 50ms for 1/240 duty operation without sacrificing sharp threshold behaviour, using a low viscosity nematic mixture. Driving method is also investigated to avoid the contrast reduction, which comes from the "frame response" phenomena in fast-responding LCDs. A multi-line selection method, where 2 or more scanning lines are selected at a time, is.proved to be a promising candidate to overcome the problem. A 5.7" diagonal color STN LCD with improved contrast, uniformity and response times has been developed, using the new nematic mixture and the driving method as well.
