1. A processing system for a capacitive sensing device, comprising:

  • a sensor module comprising sensor circuitry configured to acquire sensor data using one or more sensor electrodes of a plurality of sensor electrodes during one or more display blanking periods, wherein a first half sensing period occurs during a first display blanking period and a second half sensing period occurs during a second display blanking period, and wherein a display update period occurs between the first display blanking period and the second display blanking period, wherein each sensor electrode comprises at least one display electrode of a plurality of display electrodes, and wherein each display electrode is configured to be driven for display updating and capacitive sensing; and

    ;

    wherein the sensor module acquires sensor data using a first resulting signal from the first half sensing period and a second resulting signal from the second half sensing period.
