Abstract

In an example, an input device includes: a plurality of transmitter electrodes including: a first transmitter electrode having a first set of sub-electrodes; and a second transmitter electrode having a second set of sub-electrodes, where the number of sub-electrodes in the first set is different than the number of sub-electrodes in the second set; a plurality of receiver electrodes; and a processing system, coupled to the plurality of transmitter electrodes and the plurality of receiver electrodes, the processing system configured to: drive, in a first mode, the plurality of transmitter electrodes with transmitter signals while receiving resulting signals from the plurality of receiver electrodes to determine changes in transcapacitance; and drive, in a second mode, the plurality of transmitter electrodes with absolute capacitive sensing signals to determine changes in absolute capacitance.
