GE Global Research, the centralized research organization of General Electric, and GE Consumer & Industrial, today announced the successful demonstration of the world’s first roll-to-roll manufactured organic light-emitting diode (OLED) lighting devices. This demonstration is a key step toward making OLEDs and other high performance organic electronics products at dramatically lower costs than what is possible today.
OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They represent the next evolution in lighting products. Their widespread design capabilities will provide an entirely different way for people to light their homes or businesses. Moreover, OLEDs have the potential to deliver dramatically improved levels of efficiency and environmental performance, while achieving the same quality of illumination found in traditional products in the marketplace today with less electrical power.
“For businesses, architects, lighting designers and anyone interested in pushing the envelope to achieve increasingly energy-efficient lighting — and vastly expanded lighting design capabilities — today marks the day that viable, commercialized OLED lighting solutions are coming into view,” said Michael Petras, GE Consumer & Industrial’s Vice President of Electrical Distribution and Lighting. “We have more work to do before we can give customers access to GE-quality OLED solutions, but it’s now easier to envision OLEDs becoming another high-efficiency GE offering, like LEDs, fluorescent or halogen.”
The development of this low cost roll-to-roll manufacturing process has the potential to eliminate the manufacturing hurdles that currently exist in preventing a more widespread adoption of high performance organic electronics technologies such as OLED lighting. The few organic electronics products on the market today are made with more conventional batch processes and are relatively high cost.
GE, as part of its ecomagination initiative, has made substantial investments in OLED research that has resulted in world records for OLED lighting device size and efficiency. In 2004, researchers were able to demonstrate an OLED device that was fully functional as a 24-inch by 24-inch panel, which produced 1,200 lumens of light with an efficiency on par with today’s incandescent bulb technology. This was the first demonstration that OLED technology potentially could be used for lighting applications. Since then, GE has more than doubled the level of OLED efficiency using device architectures that are scalable to a large area and can be produced cost-effectively.
The efforts to increase the efficiency and performance of OLED lighting have coincided with the development of a low-cost, roll-to-roll process for manufacturing these devices. The ultimate goal of GE’s research program is to introduce OLED lighting products to market by the year 2010.
