Patent ID: 8358276

Claim:
A capacitive touch sensor panel, comprising: a substrate formed from a dielectric material; a first plurality of traces of conductive material located on a first side of the substrate, each of the first plurality of traces comprising a first central trace arranged along a first dimension of a two-dimensional coordinate system and a plurality of first trace branches at least one of plurality of first trace branches protruding from both sides of the first central trace in a substantially straight line, the plurality of first trace branches extending substantially perpendicularly from the first central trace in a second dimension of the two-dimensional coordinate system; and a second plurality of traces of the conductive material located on a second side of the substrate, each of the second plurality of traces comprising a second central trace arranged substantially along the second dimension and a plurality of second trace branches extending from the second central trace , at least some of the plurality of second trace branches comprising first extension branches, at least one of the first extension branches protruding from both sides of the second central trace in a substantially straight line, the first extension branches extending substantially perpendicularly along the first dimension from one of the second central traces and a plurality of second extension branches extending substantially perpendicularly along the second dimension from each of the first extension branches, the plurality of second extension branches interdigitated with the plurality of first trace branches.
