Claim Text:
1. An apparatus comprising: an array of capacitive sensor electrodes comprising a plurality of distinct capacitive sensor electrodes distributed over a sensing area; conductive traces connected to respective ones of the plurality of distinct capacitive sensor electrodes; and a shield electrode overlying, in the sensing area, conductive traces and portions of at least some of the sensor electrodes; wherein the shield electrode overlies, in the sensing area, and covers all of the conductive traces; wherein the shield electrode overlying portions of at least some of the sensor electrodes defines uncovered portions of the sensor electrodes as operational sensor electrodes of equal operational size; and wherein the shield electrode extends across the whole sensing area as a strip except at openings through the shield electrode to the underlying capacitive sensor electrodes, the openings defining multiple parallel shielding strips, each parallel strip associated with each row of capacitive sensor electrodes, the portions of the sensor electrodes that are uncovered defining operational sensor electrodes of equal operational size.
