In one embodiment, a device includes a display stack including a number of layers. The layers include a cover layer and one or more other layers. The device also includes a touch sensor disposed on a surface of a particular layer of the plurality of layers of the display stack. The touch sensor includes a number of first electrodes oriented along a first direction. Each of the first electrodes includes a plurality of first conductive regions. The touch sensor also includes a number of second electrodes oriented along a second direction that is substantially perpendicular to the first direction. Each of the second electrodes includes 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.
