Emerging Technologies

Organic light-emitting diodes (OLEDs) are ultra-thin light sources that consist of thin layers of organic semiconductor materials and can generate light in almost any color. Up to now, they were primarily used in mobile device displays and high-end TVs. However, as flexible area light sources they open up completely new design possibilities and are increasingly moving into the spotlight of the high-end automotive and the lighting industry.

VON ARDENNE is working on the development of scalable technologies for the production of OLEDs on flexible substrates such as metal strip, polymer films, and flexible glass. We do this in cooperation with industrial partners and research institutions.

Our pilot coating equipment R2Flex300, which was installed at Fraunhofer FEP, transfers the layer system technology developed by our partners on 300 mm wide flexible substrates by means of roll-to-roll coating. It is our aim to produce highly efficient white OLEDs that are suitable for lighting purposes.

We use VON ARDENNE linear organic evaporators as technological key components for the deposition of OLED materials.
