More Information
Summary: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 that includes driver circuitry, the driver module coupled to source lines and sensor electrodes. Each sensor electrode including one or more common electrodes configured for display updating and input sensing. The driver module is configured to select a first display line for display updating during a first display update period, drive the sources lines with first display update signals during the first display update period to update the first display line, drive a first sensor electrode of the plurality of sensor electrodes for capacitive sensing during a non-display update period, and operate the source lines in a restore mode during a restart period, wherein the restart period is after the non-display update period and before a second display update period.
