GE Demonstrates World's First ''Roll-to-Roll'' Manufactured OLEDs

GE Global Research today announced the successful demonstration of the worlds first roll-to-roll manufactured 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.

Researchers have long dreamed of making OLEDs using a newspaper-printing like roll-to-roll process, said Anil Duggal, manager of GEs Advanced Technology Program in Organic Electronics. Now weve shown that it is possible. Commercial applications in lighting require low manufacturing costs, and this demonstration is a major milestone on our way to developing low cost OLED lighting devices.

Duggal continued, Beyond OLEDs, this technology also could have broader impact in the manufacturing of other organic electronic devices such as organic photovoltaics for solar energy conversion, sensors and roll-up displays.

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 & Industrials 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 its now easier to envision OLEDs becoming another high-efficiency GE offering, like LEDs, fluorescent or halogen.

The demonstration of a low-cost, roll-to-roll process for OLED lighting represents the successful completion of a four-year, $13 million research collaboration among GE Global Research, Energy Conversion Devices and the U.S. Commerce Departments National Institute of Standards and Technology (NIST). The goal of the collaboration was to demonstrate a cost-effective system for the mass production of organic electronics products such as flexible electronic paper displays, portable TV screens the size of posters, solar powered cells and high-efficiency lighting devices.

ECD Senior Vice President Nancy Bacon said, This program was a major step in developing high volume roll-to-roll manufacturing for OLEDs and other organic semiconductor devices. The success of this program is testimony to the effectiveness of NISTs advanced technology program model, and our 20-year history of pioneering research in roll-to-roll technology. We currently are utilizing this technology to mass produce our flexible, durable and lightweight UNI-SOLAR brand solar laminates. ECD looks forward to continuing collaboration with GE to further develop this technology for future commercialization.

GE researchers provided the organic electronics technology and were responsible for developing the roll-to-roll processes, while ECD provided its unique roll-to-roll equipment-building expertise to build the machine that manufactures the OLED devices. The machine is being utilized for further manufacturing research at GEs Global Research Center in Niskayuna, New York.

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 unique commercial equipment and technology needed to enable high performance-based organic electronics products does not currently exist. The few organic electronics products on the market today are made with more conventional batch processes and are relatively high cost. A roll-to-roll manufacturing infrastructure that enables high performance and low cost devices will allow a more widespread adoption of organic electronics products.
