Researchers develop higher-efficiency LEDs

Nilay Patel

Terrific-looking LED-backlit HD displays were all over CES this year, and it sounds like they're only going to get better -- scientists from Renessalaer Polytechnic Insitute and Samsung have developed a new polarization-matched LED that cranks out 18 percent more light while being 22 percent more efficient than traditional LEDs. The improved performance is due to a reduction in "efficiency droop," which causes regular LEDs to turn less power into light when fed higher currents -- the team replaced the traditional active layer of the LEDs with a new specially matched layer. No word on when any of this is coming to market, but we're holding out hope for CES 2010.
