Philips plugs OLEDs into wall socket
9/8/2010 1:58 PM EDT
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.

WOW!! That is a great news from Philips and another innovation in the area of lighting. This technology can definitely be the driver for the low power consumption in all the consumer lighting applications in the future. OLED displays which were already being employed in the consumer electronics such as active dial wrist watches are the corner of the Philips innovation. Power consumption is the key eveywhere!!!

Does anyone have tech. info about this device? How do they do it? How does the efficiency compare with current production LEDs?

There is also a patent application by Jacobs & Hente, resembling the press release, at the World Intellectual Property Organization site www.wipo.int # WO/2009/156925. It has a sketchy circuit diagram but no hard information.

I wonder about the cost of this new technology compared to the state-of-the-art. Any ideas out there?

well I do agree that removing the conversion mechanism feels like a big deal (and I really appreciate the URL by matthoff) it's unclear what's lost in efficiency with the proposed solution... unclear to me on the first scan of the URL anyway. I admit that I envisioned a light bulb replacement without high- to low-voltage conversion and this sure isn't that.

These days everyone is looking to reducing the cost of using energy. What this does is to promote the notion of going GREEN. Something is always lost in conversion. By using AC instead of DC, you win what is lost.
