Abstract
In one embodiment, a touch sensor includes a substrate and a plurality of columns of electrodes disposed on a side of the substrate. Each column includes a drive electrode and a plurality of sense electrodes. The plurality of columns includes a first column, a second column, and one or more interior columns between the first and second columns. The drive electrode of a particular interior column of the one or more interior columns includes a main electrode line that extends a length of the particular interior column such that a first sense electrode and a second sense electrode of the sense electrodes of the particular interior column are located on opposite sides of the main electrode line of the drive electrode.
