Abstract: A touch panel includes a. plurality of electrodes arranged in an electrode array, wherein the plurality of electrodes includes a plurality of touch panel elements. A controller is configured to measure a charge that flows into or out of an electrode of the electrode array when the electrode is charged or discharged to a particular voltage, and configured to connect neighboring electrodes in the electrode array to a reference potential and to a voltage waveform. A sensing system makes a first measurement of the charge flowing into or out of the electrode while a set of neighboring electrodes are driven with the voltage waveform, and makes a second measurement while the set of neighboring electrodes are connected to the reference potential. The controller further is configured to distinguish conductive from non-conductive objects, based on a comparison of the two measurements.
