DOE SOLID STATE LIGHTING INITIATIVE
The U.S. Department of Energy (DOE) initiated its solid-state lighting (SSL) program in 2000 to fund the research and development of inorganic LEDs and OLEDs as prospective next-generation lighting sources. Since then, Universal Display has made considerable progress in WOLED development through a number of DOE research contracts.
Thanks to these programs, Universal Display has been recognized for setting performance records with its proprietary PHOLED and WOLED technologies. In 2004, we demonstrated an OLED with a record 20 lm/W. Then, in 2007, the DOE honored Universal Display for its team’s demonstration of a 30 lm/W device, at a CRI of 70, and a new record external quantum efficiency (EQE) of 30% at 850 nits using a novel light extraction technique. Most recently, we reported a record power efficiency of 102 lm/W. These achievements represented important steps toward DOE’s long-term SSL research goal of a 150 lm/W device in a cost-effective, market-ready white lighting OLED product.
