OLED Breakthrough Yields 75% More Efficient Lights

Posted by kdawson on 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."

    I'm just going to buy lights that are 75% brighter.

  2. 43% less power, you mean by JasperKlewer · · Score: 5, Interesting

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

    Now _that_ is a cool name for a scientific journal. I can imagine reading it now...

    [Me]: Wow, OLED's use 75% less energy now!
    -turns pages-
    [Me]: Oh, fusion! That was fast!

    Sounds like a great new technology but I get frustrated when product seems to take forever to get to market.

    (1) OLED Breakthrough Yields 75% More Efficient Light
    (2) ...reducing the ultra-thin lightsâ(TM) energy consumption by 75%
    (3) increases photoluminescence emission rates by 1.75 times
    (4) increases light intensity twofold.

    *Four* numerical figures, and no two of them compatible in any way.

    (1): "a 75% more efficient light" would mean an increase to 175% or original, a factor of 1.75 times better.
    (2): "reducing by 75%" means a factor of 4 better.
    (3): "increases photoluminescence emission rates by 1.75 times" means a 2.75 time increase, a factor of 2.75
    (4): "increases light intensity twofold" is a factor of 2.

    All incompatible. Wonder what the real numbers are?
