Abstract: A touch screen (500) can include electrodes (520, 540) (e.g., first and second touch electrodes, reference electrodes) on opposite sides (e.g., top and bottom) of a substrate (510). In some examples, vias (618, 638) can be used to couple the touch electrodes (520, 540) to conductive connections (518, 538) of flex circuits (502, 522) such that the connections (604, 624) to the flex circuits (502, 522) can be on the same side of the substrate (510) even if the touch electrodes (520, 540) are on opposite sides of the substrate (510). The conductive filling material of the via (618) can make direct contact with the conductive connections (604, 624) of the flex circuits (502, 522), for example.
