Virtual geometries for integrated display and sensing devices

摘要

Embodiments of the present invention generally provide a processing system for a display device integrated with a capacitive sensing device. The processing system includes a driver module including driving circuitry. The driver module is coupled to a plurality of common electrodes configured to be driven for display updating and capacitive sensing. A first transmitter electrode includes a first set of common electrodes of the plurality of common electrodes. A second transmitter electrode includes a second set of common electrodes of the plurality of common electrodes. A first common electrode of the second transmitter electrode is interleaved between a first pair of common electrodes of the first transmitter electrode. The processing system further includes a receiver module coupled to a plurality of receiver electrodes and configured for receiving resulting signals with the receiver electrodes and a determination module configured for determining positional information based on the resulting signals.
