Main approach to obtain a multistabilized SmA LC device is to drive the orientations of the SmA LC through applying an in‐plane or an out‐plane electric field. To get better electric‐optical performances of the SmA LC device, an idea of the improvements on the electrode structure and the surface treatment of the cell is introduced here The experimental observations on the modification SmA LC device exhibit not only a high contrast ratio but also a low driving voltage.
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.
