An optical touch panel integrated with fingerprint recognition function has been proposed and confirmed. Through tactical design with slanted grating and appropriate pitch, efficient coupling of waveguide mode for touch sensing and sufficient non-overlapping area for fingerprint detecting were obtained simultaneously, meaning great potential for intelligent touch devices.
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.
