Aixtron participates in Germany’s ‘So-Light’ OLED R&D project

Deposition equipment maker Aixtron AG of Herzogenrath, Germany says that it is to participate in a new national R&D project focusing on the development of organic light-emitting diode (OLED) displays and lighting applications, with the target of strengthening Germany’s leading position in the fast growing OLED market.

The ten other partners in the project are Novaled AG Dresden, Sensient Imaging Technologies GmbH, Westfälische Wilhelms University of Münster, Fraunhofer IPMS Dresden, Symboled GmbH, Fresnel Optics GmbH, Hella KGaA Hueck & Co, Siteco Beleuchtungstechnik GmbH, AEG-MIS GmbH and the University of Paderborn.

Funded by the German Federal Ministry of Education and Research (BMBF), the €14.7m, three-year project ‘So-Light’ (Special organic Light) will focus on specific OLED applications, such as special lighting systems and displays. The technological focus will be on novel materials (transport materials, triplet emitter, redox dopants and matrix materials), improved optical systems, and process technologies for small-molecule-based OLEDs. Aixtron will take the lead in the latter area through the optimization of its proprietary OVPD (organic vapor phase deposition) technology. Other project deliverables will be application studies and demonstrator devices for specific applications such as automotive or architectural lighting and backlights for large displays.

The OVPD technology has been licensed by Universal Display Corp (UDC) of Ewing, NJ, USA exclusively to Aixtron for equipment manufacture. It is based on an invention by professor Stephen R. Forrest et al of Princeton University, USA that was exclusively licensed to UDC. Aixtron and UDC jointly developed and qualified OVPD pre-production equipment.

“OLEDs and its application for special lighting and signage purposes is one of our strategic research targets,” says professor Michael Heuken, vice president R&D at Aixtron. “The So-Light project partners share the vision that OLEDs will play an important role to provide environmentally friendly light sources combined with novel design opportunities,” he adds.
