Abstract
An active-matrix touchscreen includes a substrate, a system controller, and a plurality of spatially separated independent touch elements disposed on the substrate. Each touch element includes a touch sensor and a touch controller circuit that provides one or more sensor-control signals to the touch sensor and receives a sense signal responsive to the sensor-control signals from the touch sensor. Each touch sensor operates independently of any other touch sensor.
