11.3: A Curvature Sensing Circuit for Flexible Display

A sensory system able to measure the geometric profile of a flexible display is proposed. The sensory system is embedded within the flexible display and manufactured by the thin-film transistor process. The sensory system provides an alternative user-display interaction for flexible display applications. A numerical interpolation technique is proposed for the display curvature computation. The sensor performances of three different materials are respectively investigated for the accuracy consideration. Preliminary results seem promising through an embodiment of the design.
