The fruits of a 10-year funded agreement with the U.S. Army that began in 2004 has paid off for Arizona State University's Flexible Display Center (FDC), who has just created the first ever flexible touchscreen display. The display is based on active-matrix electrophoretic technology from E-Ink Corp out of Cambridge, MA, and will find initial application as a military device.
"Our displays have always been flexible, but so far the touchscreens have been glass, which are not rugged enough for many applications," said Sri Peruvemba, E-Ink's VP of marketing. "Now we have a partner that can build a flexible touchscreen to match our flexible display."
That partner is DuPont Teijin films, who manufacturers the plastic used in place of glass in conventional touchscreens. In this case, amorphous silicon thin-film transistors were fabricated on DuPont's flexible Teonex polyethylene napthalate substrate. The end result is a rugged, light-weight device suitable for battlefield scenarios.
Beyond military use, Peruvemba said the technology could become commercially available in as little as 18 months.
