Claim:
1. An input device comprising: a display film stack configured to display an image thought a top surface, the display film stack comprising: an electrically conductive shield having an areal extent approximately equal or greater than an active area of the plurality of sensor electrodes, the electrically conductive shield disposed below the matrix array and routing traces relative to the top surface; a compressible layer disposed below the display film stack, the compressible layer configured to allow the display film stack to deflect in response to a normal force applied to the top surface of display film stack; and a processing system coupled to the plurality of routing traces and to the electrically conductive shield, the processing system configured to operate the plurality of sensor electrodes for touch sensing and to operate the electrically conductive shield with a signal that mitigates changes in background capacitance across the plurality of sensor electrodes as the displace stack bends.
