Currently, OLEDs require low-voltage direct current (DC) sources. The alternating current (AC) powered white-light module developed by Philips Research can be plugged directly into a wall socket. The prototype suggests future products could eliminate the cost and bulk of for power management conversion circuitry OLEDs need today.

¡°We have combined proprietary interconnect and packaging technology to create this demonstrator,¡± said Dirk Hente a researcher at Philips, speaking in a press statement. ¡°We¡¯re already seeing AC-driven LEDs coming onto the market. Our prototype marks a breakthrough step towards a similar evolution in OLEDs,¡± he said.

 OLEDs have some advantages in the quality of light they emit and their compact size compared to other light sources including existing LEDs, Philips said in a statement. The company already sells a line of commercial and industrial OLEDs for lighting.

 Philips Research developed its AC-powered module as part of the TOPSA 2012 project funded by the German Federal Ministry of Education and Research. The work was done in collaboration with the Institut f¨¹r Hochfrequenztechnik in Braunschweig, Germany.
