Breakthrough Yields Brighter OLEDs, Could Be Used For Lighting

Typically with OLEDs, only 20 percent of the light is generated by the device. This makes there brightness inferior to LEDs, making them a poor choice for lighting. However, in a significant breakthrough, researchers at the University of Michigan and Princeton University have developed an OLED/microlense combination material that boosts illumination by over 60 percent, bringing it into the realm of respectability.

The research was led by Stephen Forrest, a professor of electrical engineering and physics at Michigan, and Yuri Sun, from Princeton University. The pair observed that in OLEDs electricity in generated by applying electricity to a thin organic layer, analogous to the semiconductor in an LED. However in OLEDs the material character internally reflects the light, forcing it to run parallel, instead of perpendicularly out of the bulb.
