Multiple bridges single sided touch sensor

摘要

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.

1. A touch sensor panel, comprising:
at least one first line formed from a plurality of first sections and a plurality of second sections of a first conductive material on a first layer, each of the plurality of first sections having a width less than each of the plurality of second sections; at least one second line formed from a plurality of third sections and a plurality of fourth sections of the first conductive material on the first layer, each of the plurality of third sections having a width less than each of the plurality of fourth sections; and a plurality first bridges of a second conductive material, each of the plurality of first bridges configured to electrically couple fourth sections, wherein an intersection of one of the at least one first line and one of the at least one second line includes first bridges crossing over at least two first sections.
