Light extraction is the process of removing light from the device itself. So when the device emits a photon, it gets trapped in the glass, in the organic layers themselves in the metals. And the-- what our challenge is, is to get all of that light into the viewing angle. So that when somebody sees the OLED they're seeing the full efficiency of that device. Rather than having light lost in the various segments.

The thing that actually converts electricity into light is the emitter itself. So there are a number of scientific challenges that are still out there in OLEDs, particularly in emitters. Even though you can go to the cell phone store and buy yourself a cell phone that's powered by OLED emitters, and active matrix OLEDs are present in cell phones and in televisions, and it leads people to think that all of the issues are solved.

OLEDs are based on organic (carbon-based) materials. Unlike LEDs, which are small point sources, OLEDs are made in sheets that provide a diffuse-area light source. While developing rapidly, OLED technology is less mature than LED technology, whose rapid advancement has created a moving target for OLED products in terms of lighting performance and pricing. Still, OLED manufacturers are optimistic that with a few key breakthroughs, OLEDs will offer a value proposition complementary with LED lighting approaches.
