PPG Industries has been awarded a USD 1.6 million grant for the development of a low-cost glass substrate to promote the commercialization and mass production of organic light-emitting diode lighting (OLEDs, made from organic materials that emit light when an electrical current is passed through them) by the U.S. Department of Energy. PPG researchers will, as part of the DOE grant, develop a coated glass substrate that is less expensive and better suited to the requirements of OLED lighting devices than existing ones, resulting in less expensive OLEDs which produce more light using less energy. According to Victoria M. Holt, PPG senior vice president, glass and fiber glass, PPG was selected for its technical expertise in glass, coatings and optical products. “The ultimate goal of the DOE is to reduce costs and energy use associated with lighting in the United States,” she said. “PPG will help make that possible by integrating OLED technology with compatible glass and coating technologies we already have in place.” PPG director of research and technology, glass and fiber glass, Mehran Arbab, said there are two PPG technologies well-suited to OLEDs. “Transparent conductive coatings and optical coatings are strong technology platforms for us. We use them to serve the solar, aerospace and architectural markets. This grant will enable us to refine them for more effective and affordable application to OLED lighting manufacture,” he explained. Universal Display Corp. (UDC), which received a related USD 4 million grant for a US-based OLED lighting panel pilot manufacturing facility, will work with PPG as a project subcontractor. UDC will build, test and collaborate in the evaluation of OLED devices engineered for the PPG substrate. PPG and UDC have partnered for almost 10 years in the development and commercialization of proprietary phosphorescent OLED materials. OLED lights are, because they are made with organic materials, environmentally friendly, and have, with advanced development, the potential to emit four times as much light per watt as conventional incandescent bulbs.
