Flexible OLED displays using plastic substrates

Organic light-emitting diodes (OLEDs) displays using plastic substrate have many attractive features. They are ultrathin and light, in addition, it will be realized the-flexible display to utilize the flexibility of the substrate. The key,issue in achieving such displays is how to protect OLEDs from moisture and oxygen. We developed a barrier film on a plastic substrate and a passivation film on the OLED device itself. As a result, the device showed good e mission characteristics after storage, and its characteristics:were almost the same as those of a device fabricated on a glass substrate. We also developed a 3-in full-color flexible OLED display.
