Abstract
A touch sensor panel can include a plurality of drive lines crossing a plurality of sense lines, forming an array. The plurality of drives lines and the plurality of sense lines can be formed by interconnecting sections of at least one conductive material with a plurality of bridges. The geometry and size of one or more of the plurality of bridges and the arrangement of the sections can be altered to reduce the overall resistance of a section, improve optical uniformity, and/or increase conductance. Additionally, the sensitivity to and differentiation between touch, hover, or proximity can be enhanced based on the number of bridges and the number of hot spots.
