Roll-to-Roll Fabrication Processes for Large-Area OLED Lighting Panels

Flexible plastic substrates were used for roll-to-roll production of organic light-emitting diodes (OLEDs) and silver-nanowire transparent electrodes were also prepared on the plastic substrates by a roll-to-roll process. All processes for fabricating OLEDs, including the moisture barrier layer, which is essential for obtaining long lifetime OLEDs, were performed in roll-to-roll processes. In this presentation, we will discuss in detail the process sequence and method for easily manufacturing long lifetime and large area OLED panels through roll-to-roll processes.
