Reducing display artifacts when resuming display updating in an integrated input device

A method of input sensing with a display device having an integrated capacitive sensing device, the method comprising:

• driving a first register element coupled to a first gate electrode to select a first display line for display updating during a first display update period;
• transferring charge from the first register element to a second register element during the first display update period;
• driving the second register element coupled to a second gate electrode to select a second display line for display updating during a second display update period;
• driving one or more sensor electrodes for input sensing during a non-display update period;
• charging a third register element during the non-display update period;
• transferring charge from the third register element to a fourth register element during the non-display update period;
• and
• driving the fourth register element coupled to a third gate electrode to select a third display line for display updating during a third display update period.

A processing system for a display device having an integrated sensing device, the processing system comprising:

• a driver module comprising driver circuitry, the driver module having outputs configured for coupling to a plurality of register elements and a plurality of sensor electrodes, the driver module configured for:
• driving a first register element coupled to a first gate electrode to select a first display line for display updating during a first display update period and transfer charge to a second register element during the first display update period;
• driving the second register element coupled to a second gate electrode to select a second display line for display updating during a second display update period;
• driving one or more sensor electrodes for input sensing during a non-display update period;
• driving a third register element during the non-display update period to transfer charge to a fourth register element;
• and
• driving the fourth register element coupled to a third gate electrode to select a third display line for display updating during a third display update period;
• and
• a receiver module configured for coupling to a plurality of receiver electrodes and configured for receiving resulting signals with the plurality of receiver electrodes when the one or more sensor electrodes are driven for input sensing.
