The goal of this program was to reduce the long term technical risks that were keeping the lighting industry from embracing and developing organic light-emitting diode (OLED) technology for general illumination. The specific goal was to develop OLEDs for lighting to the point where it was possible to demonstrate a large area white light panel with brightness and light quality comparable to a fluorescent source and with an efficacy comparable to that of an incandescent source. It was recognized that achieving this would require significant advances in three areas: (a) the improvement of white light quality for illumination, (b) the improvement of OLED energy efficiency at high brightness, and (c) the development of cost-effective large area fabrication techniques.
