Organic light emitting devices on polymer substrates

Abstract

We have developed an organic light emitting device fabricated on polymer film substrate (F-OLED). This device has thin film multi-layered structure; substrate / gas barrier film / transparent anode / organic emitting layers / metal cathode / passivation film, and also has a lot of attractive features, approx. 0.2mm thickness, approx. 1gr weight (including driving IC), slightly bendable and so on. It utilizes silicone oxynitride (SiON) on the substrate side as gas barrier film and silicone nitride (SiNx) as passivation film on the device side, so it makes possible to keep a good luminance after 500 hours storage test under 60deg.C.95%RH.
