OLED Breakthrough Yields 75% More Efficient Lights

Posted by kdawson on Friday July 17, 2009 @02:23AM from the mehr-licht dept.

Mike writes "Researchers at Korea's Advanced Institute of Science and Technology recently announced a breakthrough in OLED technology that reduces the ultra-thin lights' energy consumption by 75%. The discovery hinges upon a new method of creating 'surface plasmon enhanced' organic light emitting diodes that boast 1.75 times increased emission rates and double the light intensity." OLEDnet notes: "The finding was published in the April issue of Applied Physics Letters and the June 25 issue of Optics Express. It will be also featured as the research highlight of the August issue of Nature Photonics and Virtual Journal of Ultrafast Science."

43% less power, you mean by JasperKlewer · 2009-07-17 02:35 · Score: 5, Interesting

The lights radiate 75% more energy. That means a reduction of power of 1 - (1/1.75) = 43%, right?

Many vapor and physical deposition processes in semiconductor manufacture take place in a high vacuum. Making OLEDs probably already requires a vacuum at one stage for such deposition. I would say the efficiency issues with this process hinge on cost, not energy, and even that seems quite manageable.
