摘要：
An apparatus and method to reduce an average scan rate to detect a conductive object on a sensing device. The method may include detecting a presence of a conductive object in a first area of a sensing device using a first scan of the sensing device, and detecting the presence of the conductive object to determine a position of the conductive object within the first area using a second scan of the first area of the sensing device. The apparatus may include a plurality of sensor elements coupled to a switch circuit. The switch circuit may include two settings for first and second scans.
