Abstract
A system includes sensor electrodes, a touch controller, and a transmitter that provides a transmitter signal of a first frequency to an electrode capacitively coupled to a given object. The touch controller is configured to: generate a sensing signal that has a second frequency different from the first frequency during a touch sensing phase and has a DC waveform during a touch identification phase; generate touch sensing signal data based on the sensing signal with the second frequency and resulting signals received from the sensor electrodes during the touch sensing phase; sense a touch object based on the touch sensing signal data; generate touch identification signal data based on the sensing signal with the DC waveform and the resulting signals received from the sensor electrodes during the touch identification phase; and identify whether the sensed touch object is associated with the given object based on the touch identification signal data.
