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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
