Last month we reported that the US DOE funded $1.2 million (out of $1.5 million) to a research at the University of Rochester aimed towards increasing the efficiency and light output of OLEDs by improving the device’s light extraction through the use of an internal scattering layer. Today we have some new information on that project.
The three-year effort aims to increase the light output of OLEDs by 3.5 times. The idea is to try and make the light within the OLED scatter randomly and then capture it in metal rods inserted into the organic diode. The researchers will collaborate with eMagin in this project.
The project is being led by Chemistry Professors Lewis Rothberg and Ching Tang. Profession Tang invented OLEDs during his work in Kodak back in the 1970s. Tang is widely recognized as one of the leaders in the organic electronic industry and in photovoltaics. In February it was announced that Tang won the 2011 chemistry Wolf Prize for these discoveries.
