A portable consumer electronic device comprising:

• an energy storage device;
• communication circuitry;
• and
• a touch screen including:
• a display;
• and
• a plurality of touch electrodes including a plurality of first touch electrodes and a plurality of second touch electrodes, the plurality of touch electrodes forming a two-axis array of touch nodes;
• wherein the plurality of second touch electrodes is configured for being sensed differentially and wherein capacitive coupling of the plurality of first touch electrodes configured as transmitter electrodes and the plurality of second touch electrodes configured as receiver electrodes is spatially patterned such that capacitive couplings above a threshold are separated along a first axis of the two-axis array of touch nodes by one or more capacitive couplings below the threshold.

A mutual capacitance touch sensor panel comprising:

• a plurality of touch electrodes including a plurality of transmitter electrodes and a plurality of receiver electrodes interleaved with the plurality of transmitter electrodes, the plurality of touch electrodes interconnected into groups forming a two-axis array of touch nodes;
• and
• a plurality of routing traces including a plurality of transmitter routing traces and a plurality of receiver routing traces, wherein the plurality of transmitter routing traces interconnect the plurality of transmitter electrodes and the plurality of receiver routing traces interconnect the plurality of receiver electrodes, wherein the plurality of transmitter routing traces or the plurality of receiver routing traces are oriented differently than the two-axis array;
• wherein a first group of the plurality of transmitter electrodes are interconnected by a first plurality of transmitter routing traces of the plurality of transmitter routing traces, and each of the first plurality of transmitter routing traces is parallel to an immediately subsequent transmitter routing trace of the first plurality of transmitter routing traces.
