A novel laser transfer technology has been developed for manufacturing large-sized organic light emitting diode (OLED) displays. OLED materials are transferred from glass donors to a substrate by laser-induced pattern-wise sublimation (LIPS). RGB pixels are precisely patterned by LIPS. The LIPS OLED device performance has been examined in comparison with conventional evaporated device. Using this technology, we have fabricated a 27.3-inch active matrix OLED display.
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.
