According to Digitimes, Taiwan's ITRI is building a Roll-to-Roll (R2R) R&D pilot line to produce flexible OLED lighting panels. The line will be operative by 2017, and will be able to produce about 700 panels per month.
ITRI's new OLEDs will be based on flexible glass substrates. Back in 2012 ITRI collaborated with Corning to develop a full roll-to-roll process on 100um flexible glass Willow glass substrates. It's likely that the new line will also use Corning's Willow glass.
