1. A device comprising:

  • a cover material;

    a black mask including an inner edge located closer to a viewable area of the device than an outer edge;

    a touch sensor comprising;

    a substrate;

    transparent touch sensor lines capable of measuring a touch signal;

    non-transparent conductive routing traces configured to transmit the touch signal and coupled to the touch sensor lines, the conductive routing traces including an inner edge located closer to the viewable area of the device than an outer edge, wherein a distance from an outer edge of the device to an inner edge of the conductive routing traces is greater than a distance from the outer edge of the device to the inner edge of the black mask; and

    an opaque passivation layer at least partially disposed between the conductive routing traces and the cover material; and

    an optically clear adhesive laminating the cover material to the touch sensor.
