Abstract
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, adhering the two substrates together with a substantially transparent adhesive, bringing column connections down to the second substrate using vias, and routing both the column and row connections to a single connection area on the second substrate. In addition, in some embodiments some of the row connections can be routed to a second connection area on the second substrate to minimize the size of the sensor panel.
