Abstract
A touch sensor panel comprising a first touch node electrode of a plurality of touch node electrodes, the first touch node electrode coupled to a first sense connection comprising a first set of traces, the first sense connection configured to have a first resistance per unit length that varies along a length of the first sense connection, and a second touch node electrode of the plurality of touch node electrodes, the second touch node electrode coupled to a second sense connection comprising a second set of traces, the second sense connection configured to have a second resistance per unit length that varies along a length of the second sense connection differently than the first resistance per unit length varies along the length of the first sense connection. An effective resistance of the first sense connection and the second sense connection are equal.
