A highly efficient OLED lighting product using allphosphorescent technology, for the first time in the world, is presented. Using proprietary blue phosphorescent emitter, 45 lm/W white emission is achieved at 2800K color temperature. The produced panel has very low driving voltage and small color shift regarding the viewing angle. The successful commercialization of all-phosphorescent technology would bring great power saving feature for OLED to compete with other technologies.
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.
