High Performance Fringe Field Switching Mode Liquid Crystal Display with Photo-alignment Technology for Vehicular Application

Abstract

We have developed a novel photo-alignment FFS-LCD (PA-FFS-LCD) with a wide nematic temperature range from -40°C to 95°C. Our developed PA-FFS-LCD shows fast gray-to-gray response time (< 20 ms at 25°C and < 300 ms at -30°C), wide viewing angle, and high contrast ratio over 1500. Image sticking was not recognized owing to a suitable configuration of pixel and common electrodes. The developed LCD can be used for vehicular application.
