15-meter roll-to-roll device is world’s longest OLED

It is the first OLED source produced using a unique roll-to-roll (R2R) process that combines the performance of an evaporated OLED stack with solution processing of auxiliary layers. Moreover, the combination improves the process reliability and enables fabrication of devices of any length. To produce the device, Fraunhofer FEP deposited an indium-tin oxide (ITO) anode onto a protective multi-layer barrier foil produced by Holst Centre. The roll was processed at Holst Centre, where slot-die coating was used to structure the anode and deposit the first layer of the OLED stack. Fraunhofer FEP then evaporated the rest of the OLED layers and finalized the devices by lamination of Holst Centre barrier. The resulting devices have good homogeneity and efficacy of 15 lumen/W at a light output of 1000 cd/m².
