Abstract
An input device for capacitive sensing includes: a plurality of transmitter electrodes and a plurality of receiver electrodes. The input device is configured to: operate in a first mode by driving sensing signals onto each of the transmitter electrodes and receiving separate detected signals corresponding to each of the plurality of receiver electrodes; and operate in a second mode by driving a common sensing signal onto a plurality of the transmitter electrodes and receiving a common detected signal corresponding to at least one receiver electrode selected from the plurality of receiver electrodes.
