1. A touch screen comprising:

  • a plurality of display pixels with stackups that each include a first element and a second element, the first element disposed in a first material layer of the stackups and the second element disposed in a second material layer of the stackups, wherein the plurality of display pixels includes;

    a first display pixel including a third element connected to the first element, the third element contributing to a first parasitic capacitance of the first display pixel, the third element disposed in a third material layer of the stackups, different from the first material layer and the second material layer; and

    a second display pixel lacking the third element and including a fourth element, the fourth element contributing to a second parasitic capacitance of the second display pixel such that the first and second parasitic capacitances are substantially equal.
