Flexible organic light-emitting diodes (OLEDs) on continuous plastic film have been successfully fabricated using full roll-to- roll (R2R) processes, including depositions of gas-barrier layers, electrodes, layered-organic semiconductors, and lamination encapsulation. The OLEDs exhibit excellent stability and high performance comparable to OLEDs on glass, with the incorporation of R2R deposited high-gas-barrier layer with a WVTR below 10-5 g/m2day. Also a strong correlation between the gas-barrier performance and the stability of the OLEDs stored in high humidity environment has been confirmed.
