Abstract
An input device includes a first sensor array having a first plurality of sensor electrodes disposed in a sensing area, wherein the first sensor array has a first pixel density, and a second sensor array having a second plurality of sensor electrodes disposed in the sensing area, wherein the second sensor array has a second pixel density different from the first pixel density. The input device also includes a processing system coupled to the second plurality of sensor electrodes and configured to electrically float a sensor electrode in the second plurality of sensor electrodes during a sensing period of the first sensor array.
