High performance and low level of image sticking fringe field switching mode liquid crystal display with photo-alignment layers
A novel photo-alignment fringe field switching mode liquid crystal display (PA-FFS-LCD) with a wide nematic temperature range from -40 degrees C to 95 degrees C was developed. The new developed PA-FFS-LCD shows fast gray-to-gray response time (<20 ms at 25 degrees C and < 300 ms at -30 degrees 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.
