Universal Display Awarded DOE Grants

Universal Display Corp. of Ewing, N.J., announced it was awarded two new Small Business Innovation Research phase I grants for $100,000 each from the US Department of Energy (DOE) for the enhancement of white organic LED (OLED) lighting using the company's phosphorescent OLED (PHOLED) technology and materials. Under the first grant, Universal Display will team up with its research partners at the University of Michigan and the University of Southern California to demonstrate a white OLED (WOLED) lighting device. Research will focus on a device structure that employs only two emissive PHOLED dopants, instead of the current three-dopant approaches, to achieve white emission. The second grant, also in conjunction with the University of ichigan researchers, aims to increase WOLED device efficiency. Specifically, research will focus on increasing light outcoupling efficiency. This will be done by reducing the refractive index contrast between the OLED layer of the device and the substrate. The team seeks to demonstrate a novel device structure with a record 50-percent total outcoupling efficiency.
