UDC nnounced that it has been awarded two new Small Business Innovation Research (SBIR) Phase I grants for $100,000 each from the U.S. Department of Energy (DOE) for the enhancement of white OLED lighting technology using the Company's high-efficiency PHOLED technology and materials.
In the first Phase I grant, Universal Display will team with its research partners at the University of Michigan and the University of Southern California to demonstrate a simplified path to a low-cost, highly-efficient WOLED™ white OLED 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 Phase I grant, also in conjunction with the University of Michigan researchers, aims to increase WOLED device efficiency. Specifically, research will key on increasing light outcoupling efficiency. This will be done through 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% total outcoupling efficiency.
