The Fraunhofer FEP announced new large-area flexible OLED lighting panel prototypes that have been fabricated on ultra-thin glass and encapsulated with a ultra-thin glass foil in the same process.

The new process developed at the Fraunhofer institute is able to deposit OLEDs on the flexible glass and encapsulation it using an additional flexible glass layer - all in a a single roll-to-roll manufacturing step.

The process uses a high-performance adhesive, that was developed in collaboration with tesa. This adhesive glass film is subsequently laminated to the OLED-coated ultra-thin glass. The panels use Nippon electric Glass' G-Leaf ultra-thin glass, and the panels are 10x25cm in size.
