Arizona State University's Flexible Display Center (FDC) recently announced a breakthrough in flexible display technology by creating the world's first 'touchscreen' active matrix display on a flexible, glass-free substrate. Achieved through a collaborative effort between the FDC and its partners E Ink Corporation and DuPont Teijin Films, this revolutionary display is the first demonstration of a flexible electronic display that enables real-time user input. This is a result of Flexible Display Center's low-temperature thin film transistor technology, DuPont Teijin Films' high-performance Teonex® polyethylene napthalate (PEN) films and E Ink's VizplexTM -ink laminate to form active matrix electrophoretic (electronic paper) displays.
The touchscreen capability in the flexible display is enabled by integrating a low-power display controller that was co-developed by E Ink and Epson and demonstrated as part of E Ink's developer's kit. The flexible touchscreen display supports real-time user input either by stylus pen or by touch, and consumes power only when the electronic paper is activated. Once sketched on the display, information can be stored or sent wirelessly before erasing.
