The Flexible Display Center (FDC) at Arizona State University announced that it has manufactured the world's largest full-color flexible OLED display, on display now at the SID Display Week in Boston. The display measures 7.4 inches diagonally and was created using mixed oxide thin film transistors (TFTs). ASU claims that the material choice makes these displays particularly cost-effective to produce, because manufacturers can reuse existing production lines rather than investing in specialized equipment. The FDC worked together with Army Research Labs scientists on this project with the intent of creating full-color flexible OLED displays for use in "thin, lightweight, bendable and highly rugged devices" — wrist-worn computers for soldiers, for instance. There's no word on when we'll see ASU's developments show up in retail products, but the university's advancements in production techniques may bode well for commercial and military use alike.
