Universal Display announced a new $750,000 SBIR Phase II project from the US Department of Energy (DOE) to develop light extraction technology for energy-efficient, solid-state lighting. The new project is titled "Novel Light Extraction Enhancements for White Phosphorescent OLEDs".
Extraction efficiency defines the amount of generated light that can be extracted, or emitted, from the device as useful light. In current OLED panels about 20% to 30% of generated light is effectively extracted as useful light.
This is the second $750,000 OLED lighting efficiency project awarded to UDC this month, the first one was about lowering the OLED device voltage.
