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

The U.S. Display Consortium (USDC), a public/private partnership chartered with developing the flexible electronics and displays industry supply chain, today announced that a recent project with Plextronics, Inc., has aided in the development of a new hole injection layer (HIL) technology to enable broad 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.

Plextronics completed a $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. These HIL products will be cost competitive and a suitable replacement for currently used PEDOT: PSS materials.

According to Shawn Williams, Plextronics' vice president 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.

Entrepreneurial companies like Plextronics are creating new technologies capable of commercial-scale performance and manufacturability, commented Michael Ciesinski, USDC’s CEO. Plextronics’ development marks a significant technology milestone for the rapidly evolving flexible and printed electronics industry. USDC leverages the results of its programs by including member companies in the testing and validation of new developments.

Plextronics has achieved very impressive results from the competitive contract with USDC, U.S. Congressman Jason Altmire (PA-04) said.  Plextronics is a great example of how the high - tech companies taking root across our region are helping to make western Pennsylvania a center for technological innovation.
