OLED Breakthrough Yields 75% More Efficient Lights

Now here's something to keep your eye on. LED (light emitting diodes) give off virtually no heat and use less electricity than a compact fluorescent bulb. I can't wait until those get cheaper. Now OLEDs (organic light emitting diodes) are...well I'm not sure what makes them different than regular LEDs besides the organic parts. It seems like cool though. Any scientists out there want to read the article to see if you can make heads or tails why the OLEDs are 75% more efficient?
