Blue LED breakthrough for efficient electronics


R&D – OLEDs (organic light emitting diodes) are the latest and greatest in television technology, allowing screens to be extremely thin and even curved, with little blurring of moving objects and a wider range of viewing angles. In these “RGB” displays, each pixel contains red, green and blue modules that shine at different relative brightness to produce any color desired.

But not all OLEDs are created equal.

Phosphorescent OLEDs, also known as PHOLEDs, produce light through a mechanism that is four times more efficient than fluorescent OLEDs. Green and red PHOLEDs are already used in these new TVs—as well as in Samsung and LG smartphones—but the blues are fluorescent. more> http://tinyurl.com/ng4l8uk
