Abstract
Systems and methods for differential parallel touch sensing are provided. An input device includes a display with an integrated touch sensor. The touch sensor includes a plurality of sets of sensor electrodes. Each set of sensor electrodes has a positive transmitter electrode, a negative transmitter electrode, and a differential pair of receiver electrodes. The differential pair of receiver electrodes includes a positive receiver electrode coupled to the positive transmitter electrode and a negative receiver electrode coupled to the negative transmitter electrode. The differential pair of receiver electrodes is disposed between the positive transmitter electrode and the negative transmitter electrode. The touch sensor as includes a sensor circuit that is configured to: drive the positive transmitter electrode with a positive sensing signal, drive the negative transmitter electrode with a negative sensing signal, receive resulting signals from the differential pair of receiver electrodes, and process the resulting signals.
