The €11-million 3-years European Flex-o-Fab project was launched in January 2013 with an aim to help commercialize flexible OLEDs. The Holst Centre, the project's coordinator, announced that the Flex-o-Fab successfully completed its goals - including developing indium-free electrodes (based on ZTO with a supporting metal grid) and brighter OLEDs (light emission was enhanced by about 30% using a plastic substrate with outcoupling features).
The project used a distributed pilot production line and associated manufacturing chain involving partners and facilities at different locations across Europe. The project partners managed to migrate key processes from sheet-to-sheet processing to roll-to-roll production. .
