A team from Arizona State University just broke new ground in OLED technology by creating the world’s largest flexible color display screen. Flexible display screens have evolved by leaps and bounds in the past few years, but this new energy-efficient display is reportedly more durable than glass. The project was part of a mandate from the US Department of Defense, which is searching for a flexible, color OLED (Organic Light Emitting Display) that can handle the rough conditions of a combat environment.

The flexible display prototype from Arizona State’s Flexible Display Centre (FDC) was created using advanced mixed oxide thin film transistors (TFTs) and it measures 7.4 diagonal inches. “This is a significant manufacturing breakthrough for flexible display technology,” said Nick Colaneri, director of the FDC in a press release. “It provides a realistic path forward for the production of high performance, flexible, full color OLED displays, accelerating commercialization of the technology in the process.”

The mixed oxide TFTs allow for a cost-effective approach to manufacturing displays that deliver high video performance with low power consumption. Furthermore, mixed oxide TFTs can be manufactured on existing amorphous silicon production lines, eliminating the need for specialized equipment and processing.

“One of the primary directives of the FDC has been to pursue approaches to flexible technologies that take advantage of existing manufacturing processes,” continued Colaneri. “This focus drove us to pursue a flexible, color display based on mixed-oxide TFTs, which are widely regarded as a strong, cost-effective alternative to low-temperature polysilicon. This display showcases the Center’s successful scale up to GEN II, and our ability to produce displays using mixed-oxide TFTs in standard process flows with our proprietary bond/de-bond technology.”

If you live in Boston, the new, full-color OLED display will be on display at SID Display Week, June 5-7, 2012 at the Boston Convention and Exhibition Center.
