Ungrounded user signal compensation for pixelated self-capacitance touch sensor panel

A method comprising:

• sensing, during a self-capacitance portion of a touch frame, first one or more self-capacitances associated with a first plurality of touch pixels on a touch sensor panel;
• sensing, during a mutual capacitance portion of the touch frame, first one or more mutual capacitances associated with the first plurality of touch pixels;
• and
• based on the first one or more self-capacitances and the first one or more mutual capacitances, sensing a single touch event associated with the touch frame.

A touch sensor panel comprising:

• a plurality of touch pixels, the plurality of touch pixels including a first touch pixel, a second touch pixel, a third touch pixel, and a fourth touch pixel;
• and
• sense circuitry configured to:
• during a first time period, drive the first touch pixel, and ground the fourth touch pixel;
• during a second time period, drive the second touch pixel, and ground the third touch pixel;
• during a third time period, drive the third touch pixel, and ground the second touch pixel;
• during a fourth time period, drive the fourth touch pixel, and ground the first touch pixel;
• during a fifth time period, drive the first touch pixel, and ground the second and third touch pixels;
• and
• during a sixth time period, drive the second touch pixel, and ground the first and fourth touch pixels.
