Abstract
Embodiments include a method (as well as an input device and processing system) that includes driving a display signal onto at least one of a plurality of display electrodes for updating a display, and driving an input sensing signal onto at least one of a plurality of sensor electrodes, where driving the input sensing and driving the display signal at least partially overlap in time. The method further includes receiving, using a coupling electrode disposed proximate to the at least one display electrode, a coupling signal that represents an effect of a signal on at least one of the display electrodes, on a signal on at least one of the sensor electrodes, acquiring resulting signals with at least one of the sensor electrodes, and adjusting the resulting signals based on the coupling signal.
