A space-efficient substantially transparent mutual capacitance touch sensor panel can be created by forming columns made of a substantially transparent conductive material on one side of a first substantially transparent substrate, forming rows made of the substantially transparent conductive material on one side of a second substantially transparent substrate and bringing column connections down to the second substrate. The columns can be routed off-panel at an edge of the second substrate. In some examples, the first and second transparent substrates formed from polyethylene terephthalate (PET). In some examples, the substantially transparent conductive material formed from Indium Tin Oxide (ITO).
