Apparatus to reduce negative pixel from capacitive touch

A mutual capacitance touch sensor panel, comprising:

• a plurality of drive electrodes formed in a first layer, each drive electrode of the plurality of drive electrodes extending along a first direction;
• a plurality of sense electrodes formed in a second layer different from the first layer, each sense electrode of the plurality of sense electrodes extending along a second direction different from the first direction;
• and
• a plurality of ground bars formed in the first layer, wherein the plurality of drive electrodes, the plurality of sense electrodes, and the plurality of ground bars are included in an array of touch pixels, each touch pixel in the array of touch pixels including one drive electrode and one sense electrode, the array of touch pixels including:
• a first touch pixel adjacent to a second touch pixel, and a third touch pixel adjacent to the second touch pixel disposed with a first ground bar of the plurality of ground bars between the first touch pixel and the second touch pixel and a second ground bar of the plurality of ground bars between the second touch pixel and the third touch pixel, wherein the first ground bar extends along the first direction and the second ground bar extends along the second direction, wherein the first touch pixel is surrounded by first portions of the plurality of ground bars, the second touch pixel is surrounded by second portions of the plurality of ground bars, and the third touch pixel is surrounded by third portions of the plurality of ground bars.
