Patent abstract

A touch sensor panel configured to mitigate the effect of parasitic capacitance on the ability of a capacitive touch sensor panel to reliably detect touch and proximity events. The touch sensor panel includes circuitry that can electrically drive a set of conductive shields that partially encapsulate various conductive components of the touch sensor panel. The touch sensor panel can also include circuitry that work to calibrate the touch sensor panel against variations in signal phase due to a parasitic capacitance.
