An improved touch screen has enhanced optical performance and aesthetic quality. The electrodes on the touch screen employ additional fine traces of conductive material to reduce the overall electrode trace resistance to increase electrical performance without sacrificing optical quality. The additional fine traces of conductive material may be placed on the top of the ITO traces or in channels inside the boundaries of the ITO traces. The additional traces preferably run the length of the ITO traces to reduce the resistance in the longer dimension. Further, the additional traces are very small in width such that in the aggregate they cover only a small portion of the ITO electrode trace in lateral dimension to reduce the visibility of the additional traces. The conductive material may also be formed as a plurality of geometric shapes substantially forming a line in the longer dimension of the transparent conductive traces to reduce the visibility of the conductive material.
