Oncell single-layer touch sensor

A device comprising:

• a display stack comprising a plurality of layers, wherein the plurality of layers comprises a cover layer and one or more other layers;
• a touch sensor disposed on a surface of a particular layer of the plurality of layers of the display stack, wherein the touch sensor comprises:
• a plurality of first electrodes along a first direction, each of the first electrodes comprising a plurality of first conductive regions;
• and
• a plurality of second electrodes oriented along a second direction that is substantially perpendicular to the first direction, each of the second electrodes comprising a second conductive region, the second conductive region of each of the second electrodes being interdigitated with a respective adjacent first conductive region of multiple first electrodes of the plurality of first electrodes such that the second electrode does not intersect in a touch sensitive area the multiple first electrodes of the plurality of first electrodes;
• and
• one or more computer-readable non-transitory storage media embodying logic that is configured to, when executed by one or more processors, cause the one or more processors to control the touch sensor.
