1. An input device comprising:

  • a lens layer;

    a display device comprising a plurality of layers, the plurality of layers comprising a display activation layer;

    a plurality of first sensor electrodes arranged with a first sensor pitch on a first layer of the plurality of layers, each first sensor electrode comprising at least one display electrode of a plurality of display electrodes; and

    a plurality of second sensor electrodes arranged with a second sensor pitch on a second layer between the display activation layer and the lens layer, the second sensor pitch greater than the first sensor pitch along at least one dimension of a sensing region of the input device,wherein each first sensor electrode and each second sensor electrode has a substantially equilateral profile within first and second dimensions of the sensing region, andwherein the substantially equilateral profile of each second sensor electrode entirely overlaps the substantially equilateral profiles of multiple first sensor electrodes of the plurality of first sensor electrodes.
