Holst Centre and Solvay showcase a large flexible 69 cm² OLED lighting panel. The panel has a 30lm/Watt efficiency.
These large-area demonstrators contain several layers deposited by solution processing at Holst Centre and additional layers applied by conventional vacuum deposition at Solvay.

Use of printing technologies on flexible substrates will enable large scale manufacturing of OLEDs for general lighting applications, and will bring some additional features: thin, flexible, and potentially transparent light sources that could be integrated in ceiling, walls, windows.

Holst Centre and Solvay says that the partners are already working on a second generation of demonstrators encompassing more solution-processed layers. This achievement clearly demonstrates the potential for high efficacy OLEDs on flexible plastic foils, opening ways to a production of low-cost, solution-processed OLED lighting tiles.
