USDC & Plextronics develop new hole-injection-layer technology for OLED displays

June 27, 2008--The U.S. Display Consortium (USDC; San Jose, CA), a public/private partnership chartered with developing the flexible electronics and displays industry supply chain, announced that a recent project with Plextronics (Pittsburgh, PA) has aided in the development of a new hole-injection-layer (HIL) technology to enable commercialization of high-performance, low-cost, organic light-emitting diode (OLED) displays.

Plextronics is an international technology company that specializes in printed solar, lighting, and other organic electronics. It completed the $590,000 project with USDC to produce a new HIL technology that is expected to improve device performance by reducing surface roughness; improving charge injection; and allowing fine-tuning of work function. The materials that Plextronics developed utilize a new approach to conductive polymer chemistry that enables significant performance improvement, and represent a cost-competitive replacement for currently used PEDOT: PSS materials.

According to Shawn Williams, Plextronics' VP of technology, "Our company has added significant in-house capabilities to allow scale-up for our new Plexcore OC as a result of our collaboration with USDC. Also, we have successfully implemented Plexcore OC in partner devices and the material has been tested in newer device architectures." Plextronic's device design, process technology, and Plexcore branded inks enable the formation of active electrical layers, which are the key drivers of printed electronics.

The USDC program is a collaborative effort of private industry and the U.S. Army Research Laboratory, located in Adelphi, MD.
