1. A touch screen comprising:
a display having an active area;
a plurality of row electrodes disposed over the active area of the display formed in a first metal mesh layer, the plurality of row electrodes including a first row electrode and a second row electrode; and
a plurality of routing traces formed in the active area in a second metal mesh layer different from the first metal mesh layer, the plurality of routing traces including a first routing trace and a second routing trace;
wherein:
the first routing trace is coupled to the first row electrode;
the second routing trace is coupled to the second row electrode; and
the first routing trace and the second routing trace both cross from inside the active area of the display to a border region outside the active area over a first edge of the display that is parallel with the plurality of row electrodes.
 
19. A device comprising:
an energy storage device;
communication circuitry; and
a touch screen comprising:
a display having an active area;
a plurality of row electrodes disposed over the active area of the display formed in a first metal mesh layer, the plurality of row electrodes including a first row electrode and a second row electrode; and
a plurality of routing traces formed in the active area in a second metal mesh layer different from the first metal mesh layer, the plurality of routing traces including a first routing trace and a second routing trace;
wherein:
the first routing trace is coupled to the first row electrode;
the second routing trace is coupled to the second row electrode; and
the first routing trace and the second routing trace both cross from inside the active area of the display to a border region outside the active area over a first edge of the display that is parallel with the plurality of row electrodes.
