Universal Display Corporation has developed a prototype OLED display that emits green light for daytime operation and infrared in the dark.

New Jersey-based Universal Display Corporation has helped to develop a prototype OLED display that emits green light for daytime operation and infrared (IR) for use in the dark.

Developed thanks to a Small Business Innovation Research (SBIR) program, the initial prototype was designed to demonstrate that an OLED display could be built that would enable soldiers in the US army to view a single display in two modes.

When the OLED display prototype is switched to operate in an IR-emission mode, it can only be read by soldiers wearing night-vision goggles, making it suitable for use in covert operations.

The 100dpi prototype was built on flexible metal foil using low-temperature, poly-silicon backplane technology from Palo Alto Research Center (PARC), and was integrated into a system for the Army by L-3 Communications Display Systems, a division of L-3 Communications Corporation.

The project complements display developments underway at the US Army's Flexible Display Center at Arizona State University, of which Universal Display is a founding member.
