Abstract:
Embodiments of the present invention generally provide a processing system for a display device having an integrated sensing device. The processing system includes a driver module coupled to a plurality of source lines and a plurality of transmitter electrodes. Each transmitter electrode includes one or more common electrodes configured for display updating and input sensing. The driver module is configured for selecting a first display line for display updating and driving the sources lines with first display update signals to update the first display line. The drive module is further configured for driving a first transmitter electrode of the plurality of transmitter electrodes for input sensing during a non-display update period and driving the source lines with restore signals during a restart period. 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.
