Brick Layout and Stackup for a Touch Screen
First Claim
1. A touch sensor panel, comprising:
- a plurality of first lines formed on a single layer and supported on one side of a substrate;
a plurality of polygonal areas formed on the same layer as the plurality of first lines; and
a plurality of connecting traces routed adjacent to the polygonal areas and formed on the same layer as the plurality of first lines, each connecting trace coupled to a different polygonal area;
wherein the plurality of first lines and the plurality of polygonal areas form an array of capacitive sensors.

Abstract
A touch sensor panel is disclosed having an array of co-planar single-layer touch sensors fabricated on a single side of a substrate. The sense (or drive) lines can be fabricated in a single strip as columnar or zig-zag patterns in a first orientation, and the drive (or sense) lines can be fabricated as rows of polygonal (e.g. brick-shaped or pentagonal) conductive areas in a second orientation. Each sense (or drive) line in the first orientation can be coupled to a separate metal trace in the border area of the touch sensor panel, and each polygonal area in the second orientation can also be coupled to a metal trace in the border area of the touch sensor panel. The metal traces can allow both the row and column lines to be routed to the same edge of the substrate for flex circuit attachment.
