DuPont been awarded a $2.25 million grant from the U.S. Department of Energy (DOE) for a two-year project to develop a solid-state lighting source. It will use organic light emitting diode (OLED) solution-processing manufacturing techniques to meet its goals.

The project will leverage DuPont’s experience in OLED development for
displays, while tailoring the technology to the requirements for
solid-state lighting, a technology that can reduce energy consumption
compared with incandescent and fluorescent lamps.

Compared to light-emitting diodes (LEDs), which are small point sources
manufactured on relatively small semiconductor wafers, OLEDs have a
surface area light source which can be made on large sheets of glass or
in a roll-to-roll process, allowing for economies in manufacturing.
Also, DuPont says OLED lighting can use less energy and provide the
same quality of light or better.

The project also reflects DuPont’s recently announced commitment to
focus on meeting four emerging global trends, one of which is
decreasing dependence on fossil fuels.
