High performance and low level of image sticking fringe field switching mode liquid crystal display with photo-alignment layers

Abstract

A novel photo-alignment fringe field switching mode liquid crystal display (PA-FFS-LCD) with a wide nematic temperature range from −40 °C to 95 °C was developed. The new 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 about 1600 owing to use an isomerization-type photo-alignment material. Image sticking was not recognized owing to a suitable arrangement of pixel and common electrodes.
