1. A capacitive touch screen comprising:
- a display device comprising a functional display element attached to a substantially transparent substrate;
a first plurality of electrodes attached to the substantially transparent substrate, wherein the first plurality of electrodes are substantially parallel in a first direction;
a pattern through which visible light emitted by the functional display does not pass, wherein each of the first plurality of electrodes are aligned within or positioned over one or more portions of the pattern; and
a second plurality of electrodes, wherein each of the second plurality of electrodes crosses each of the plurality of first electrodes and each of the second plurality of electrodes is configured to capacitively couple with each of the first plurality of electrodes.
