Philips claims first AC-powered OLED module

Various sources
10 September 2010

Scientists from Philips Research have developed the first-ever organic light emitting diode (OLED) module that can be powered directly from a main electricity supply. The prototype opens the door to OLED systems that can be directly plugged into standard power outlets without the need for bulky power management circuitry. This will reduce the bill of materials and simplify luminaire design for future OLED-based systems aimed at mass-market general illumination applications.

Until now, the physical characteristics of OLEDs have meant they have had to be powered from low-voltage direct current (DC) sources. In contrast, the AC-powered white-light module developed by Philips Research can be plugged directly into a mains wall socket.

"We have combined proprietary interconnect and packaging technology to create this demonstrator," says Dr. Dirk Hente of Philips Research. "We're already seeing AC-driven LEDs coming onto the market. Our prototype marks a breakthrough step towards a similar evolution in OLEDs."

Philips Research has developed its AC-powered module in collaboration with Dipl.-Phys. Holger Spahr, Institut für Hochfrequenztechnik, TU Braunschweig, Germany as part of the TOPAS 2012 project. This project, funded by the German Federal Ministry of Education and Research (BMBF), brings together leading industrial and academic organizations to develop OLEDs for lighting systems of the future.
