Fraunhofer's COMEDD developed new color tunable OLED lighting panels. These new panels will be presented at the LOPE-C 2013 exhibition (June 11) for the first time. To develop these new panels, the Fraunhofer used vertical stacking of OLED emitters which can be controlled separately.

They say that by using different process technology, COMEDD was able to achieve the right stack architecture including the optimized thickness of the individual OLEDs for an appropriate efficacy.

COMEDD will also show OLED Microdisplays and flexible OLED lighting panels at the exhibition. It seems that those will be the same flexible panels shown back in 2011. These 30-cm wide panels were developed using a roll-to-roll process.
