Abstract
A touch sensor includes a substrate and a plurality of columns of electrodes disposed on a first side of the substrate. The substrate includes a first end and a second end opposite the first end. The columns each include a sense electrode and drive electrodes. The columns include a first column adjacent to the first end, a second column adjacent to the second end, and one or more interior columns. The touch sensor also includes a plurality of channels for routing tracks coupled to the drive and sense electrodes. Tracks for the first column are routed in a first channel on a side of the first column opposite from the first end of the substrate. Tracks for the second column are routed in a second channel on a side of the second column opposite from the second end of the substrate. Tracks for the interior columns are dispersed amongst the channels.
