Universal Display awarded three new OLED lighting DOE grants

The US Department of Energy (DOE) has awarded three new OLED lighting small-business grants to Universal Display. The largest project is in Phase II already, and is focused on the development of “ultra-high-efficiency” phosphorescent OLEDs for lighting applications". UDC will produce a white OLED that features 120lm/W efficiency by improving out-coupling of light from the OLED structure through high-index substrates and low-voltage operation.

The second will focus on thermal management issues and optical improvements. UDC will make 15cm square panels with various designs, to see the thermal impacts of each. Lower temperature operation will help to extend the lifetime of the OLEDs.

The last project addresses light extraction issues. UDC will develop low-cost thin materials that has improved light extraction.
