Universal Display Corporation today announced that it has been awarded a Small Business Innovation Research (SBIR) Phase II grant for $750,000 from the U.S. Department of Energy (DOE) to develop power-efficient WOLED™ white OLED technology for future solid-state lighting applications.
Through this Phase II program, Universal Display is seeking to demonstrate novel WOLED device designs that offer further enhancements in power efficiency and operating lifetime based on the Company’s proprietary PHOLED technology. The DOE has developed a technology roadmap suggesting a feasible path for white OLEDs to achieve power efficiencies of 100 to 150 lumens per Watt (lm/W). Universal Display’s PHOLED technology is a critical element for achieving this goal. The Company recently announced a white PHOLED with a power efficiency of more than 30 lm/W and external quantum efficiency (EQE) of 29 % at 850 nits, which the Company believes is the highest EQE reported to date. Through programs such as this one, Universal Display hopes to achieve continued performance gains toward the DOE’s roadmap goals.
The new program will also leverage the Company’s proprietary OVPD™ organic vapor phase deposition processing technology. OVPD technology offers the potential to optimize organic layer thicknesses, doping concentrations and the interfaces between the layers, and also to provide excellent film uniformity over large areas.
