Abstract:
The disclosure is directed to piezoelectric film structures and sensors, and display assemblies using same. The piezoelectric film structure is transparent and includes: a substrate; a bottom optical layer disposed on or above the substrate; a bottom conducting layer disposed on or above the bottom optical layer; at least one piezoelectric layer disposed on or above the bottom conducting layer; a top conducting layer disposed on or above the at least one piezoelectric layer; and a top optical layer disposed on or above the top conducting layer. The sensor includes the piezoelectric film structure electrically connected to a signal processing system. The display assembly includes the sensor operably arranged relative to a display device. The piezoelectric film structures and sensors can be configured to determine one or more touch-sensing features associated with a touch event.
