Researchers from the University of Michigan, in collaboration with Universal Display are developing a low-cost roll-to-roll (R2R) process to produce flexible OLED lighting panels. The goal is to achieve a panel cost of less than $10 per klm - a tenfold reduction compared to current costs.

The roll-to-coll system can continuously produce encapsulation panels, at high speeds and reduce costs. The front plane (organic stack) deposition is done via OVPD. The researchers say the will demonstrate reliable, encapsulated 25 cm2 flexible white OLED panels with an efficacy of 50 lm/W and a CRI >85 on barrier-coated plastic films or thin glass.
