Patent ID: 8633915

Claim:
A touch sensor panel, comprising: a plurality of patterns of conductive material disposed along a first direction, formed on a single layer and supported on one side of a substrate; and a plurality of distinct patches of the conductive material supported on the same side of the substrate as the plurality of patterns of conductive material, the plurality of distinct patches disposed in substantially the same single layer, and plural groups of the plurality of distinct patches disposed along a second direction, different from the first direction, the distinct patches in a particular group connected together via at least one of a plurality of conductor traces; wherein at least sections of the plurality of distinct patches are separate from, non-overlapping with, and adjacent to sections of the plurality of patterns of conductive material such as to form a substantially co-planar, single layer array of mutual capacitance sensors, each mutual capacitance sensor responsive to a fringing electric field between a section of one of the plurality of distinct patches and an adjacent, non-overlapping, co-planar section of one of the plurality of patterns of conductive material; and wherein: the plurality of patterns of conductive material disposed along the first direction is configured as one of a drive line or a sense line for the array of mutual capacitance sensors, and the plurality groups of the plurality of distinct patches disposed along the second direction is configured as the other of the drive line or the sense line for the substantially co-planar, single layer array of mutual capacitance sensors; and in operation, the drive lines driven with one or more stimulation signals to establish the fringing electric field for coupling charge onto the sense lines.
