Efficiency Jump for White OLEDs
November 21, 2006 | Source: Technology Review
In an advance that could hasten the day when energy-efficient glowing plastic sheets replace traditional lightbulbs, a method for printing microscopic lenses nearly doubles the amount of photons coming out of the materials, called organic light-emitting diodes, or OLEDs.
The technology increases the light output of the thin, flexible OLEDs by 70 percent, bringing them closer to being competitive with white-light sources.
