LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.

Flexible OLED aimed US Army

US researchers are claiming the largest flexible colour OLED display using mixed oxide thin-film transistors – a 7.4in device for the US Army, writes Steve Bush.

“It meets a critical target set by the US Department of Defense to advance the development of full-colour, full-motion video flexible OLED displays for use in thin, lightweight, bendable and rugged devices,” said Arizona State University’s Flexible Display Center (FDC).

“One of the primary directives of the FDC has been to pursue approaches to flexible technologies that take advantage of existing manufacturing processes,” added Centre director Nick Colaneri. “This focus drove us to pursue a display based on mixed-oxide TFTs, which are widely regarded as an alternative to low-temperature polysilicon.”
