Abstract
An apparatus may include a touch sensor where the touch sensor has a first set of electrodes and a second set of electrodes that are electrically isolated from the first set of electrodes, a shield layer positioned adjacent to the touch sensor where the shield layer has a first section and a second section where the first section of the shield layer has a different electrical characteristic than the second section of the shield layer, and a ground feature incorporated into the touch sensor.
