SINGLE-LAYER TOUCH-SENSITIVE DISPLAY
First Claim
1. A touch sensor panel, comprising:
- a plurality of columns of a conductive material formed on a single layer and supported on one side of a substrate; and
a plurality of patches of the conductive material supported on the same side of the substrate as the plurality of columns, the plurality of patches formed on the same layer as the plurality of columns adjacent to the plurality of columns and arranged in a plurality of rows, each patch in a particular row connected together;
wherein each of the plurality of patches and each of the plurality of columns form a portion of a capacitive sensor.

Abstract
A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is disclosed. The drive and sense lines can be fabricated as column-like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.
