Plextronics has completed a $590,000 project with the U.S. Display Consortium (USDC) to enable broad commercialization of high-performance, low-cost, organic light-emitting diode (OLED) displays. The project involved development of a new hole injection layer (HIL) technology that is expected to reduce surface roughness, improve charge injection, and allow fine tuning of work function.
The materials that Plextronics developed use 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.
“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,” said Shawn Williams, Plextronics’ vice president of technology. “Also, we have successfully implemented Plexcore OC in partner devices and the material has been tested in newer device architectures.”
Plextronics’ 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 in Adelphi, Md.
