Philips plugs OLEDs into wall socket

SAN JOSE, Calif. – Philips Research has developed an organic light emitting diode module that can be powered directly from a standard wall outlet, accelerating the move to create mainstream OLED products.
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 für Hochfrequenztechnik in Braunschweig, Germany.
