Abstract
A sensing circuit includes: a plurality of sensor electrodes; a first capacitance between the sensor electrodes; a plurality of proximity sensing electrodes electrically isolated from the sensor electrodes; and a second capacitance between at least one of the sensor electrodes and the proximity sensing electrodes. A density of at least one of the proximity sensing electrodes is less than a density of at least one of the sensor electrodes.
