U.S. Department of Energy Honors PPG Scientists for Advances in OLED
PPG develops low-cost integrated glass substrate for commercial OLED lighting
PITTSBURGH -- March 20, 2013
PPG Industries (NYSE:PPG) has been recognized by the U.S. Department of Energy
(DOE) for “significant achievements” in advancing organic light-emitting diode
(OLED) lighting technology. Dennis O’Shaughnessy, Ph.D., PPG associate
director for flat glass research and development, accepted the award on behalf
of the PPG team during the 2013 Solid-State Lighting (SSL) R&D (Research and
Development) Workshop in Long Beach, Calif.
PPG’s advances are the result of a two-year project initiated with the DOE in
2010 to promote the commercialization and mass production of OLED lighting.
The PPG team led by Abhinav Bhandari, Ph.D., project engineer, has
demonstrated a float glass-based integrated substrate with scalable
light-extraction technologies and transparent conductive films for OLED
The results indicate significant cost and performance advantages over
conventional indium tin oxide (ITO)-coated display-grade glass substrates.
PPG’s light-extraction technologies are compatible with the conventional float
glass manufacturing process and result in significant enhancement of device
efficiencies, according to O’Shaughnessy.
Dick Beuke, PPG vice president, flat glass, said the new glass substrate is
one of several major initiatives PPG is advancing to reduce energy use in the
U.S. “At PPG, we are proud to be developing glass technologies to make OLED
lighting more viable for mass use,” he said. “This research enhances and
complements the work our scientists are doing in architectural glass and
coatings to make homes and buildings more energy efficient, and in solar
technology to help that industry achieve grid parity.”
Mehran Arbab, Ph.D., PPG director, glass science and technology, said, “OLED
lights have the potential to emit four times as much light per watt as
incandescent bulbs. Widespread commercial use of this technology could
significantly reduce energy use in homes, buildings and workplaces.”
PPG was the only company honored in the OLED lighting area at the three-day
workshop, which brought together nearly 300 researchers, manufacturers and
industry insiders who are promoting and monitoring the latest developments in
SSL technology. The DOE supports SSL R&D efforts to accelerate market
introduction of high-efficiency, high-performance SSL products. Its mission
for the SSL R&D portfolio is to “create a new, U.S.-led market for high
efficiency, general illumination products through the advancement of
semiconductor technologies, to save energy, reduce costs and enhance the
quality of the lighted environment.”
