Hole injection layer technology for low-cost OLED displays

A recent project by the U.S. Display Consortium (USDC), a public/private partnership chartered with developing the flexible electronics and displays industry supply chain, 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.
