Blue Flexible Transparent Organic Light-Emitting Devices

Abstract

Blue transparent organic light-emitting devices (TOLEDs) and blue flexible OLEDs (FOLEDs) have been fabricated on glass and plastic films, respectively. We have also fabricated blue flexible transparent OLEDs (FTOLEDs) having both flexibility and transparency by using indium-tin-oxide:cesium (ITO:Cs) as a cathode. A Cs-incorporated ITO electrode is useful for the fabrication of not only a TOLED on a glass substrate but also a flexible TOLED on a plastic film.
