DuPont Gets DOE Grant For OLED Development
By Greg Tarr -- TWICE, 11/16/2009
Wilmington, Del. - Chemical industry giant DuPont said Monday the U.S. Department of Energy (DOE) has awarded it a $2.25 million grant for a two-year project to develop a solid-state lighting source using manufacturing techniques for low-cost OLED solutions.
DuPont said it will use the funding in the development of low-cost, energy-efficient OLED lighting solutions.
The project will leverage DuPont's experience in solutions processing for OLED displays to address the unique requirements of solid-state lighting, which is expected to significantly reduce energy consumption compared with incandescent and fluorescent lamps.
Dupont Solution processing is a cost-effective technique for the manufacture of OLEDs due to its lower capital investment, reduced fixed costs and efficient use of materials. The benefits are seen through manufacturing large areas at low cost while delivering completely new, highly efficient lighting concepts, DuPont said.
DuPont released a study from the Next Generation Lighting Industry Alliance showing that more than 20 percent of U.S. electrical energy in 2009 is used for lighting. The U.S. domestic market for lamps, ballasts, lighting fixtures and lighting controls is $15 billion and $75 billion, globally. Solid-state lighting technologies, which include OLEDs, have the potential to save 348 trillion kilowatt-hours of electricity by 2030 compared with traditional light sources, DuPont sai.d
Compared to LEDs, which are small point sources manufactured on relatively small semiconductor wafers, OLEDs have a surface-area light source that can be made on large sheets of glass or in a roll-to-roll process, allowing significant economies in manufacturing, DuPont said.
