1. A touch screen, comprising:
a substrate;
a first touch electrode on a first side of the substrate;
a second touch electrode on a second side of the substrate different from the first side of the substrate;
a first flex circuit coupled to first touch circuitry, the first flex circuit including a conductive connection, wherein the first touch electrode and the conductive connection of the first flex circuit are disposed on a same side of the substrate in the touch screen; and
a first via including a conductive material, the first via configured to electrically couple the first touch electrode to the conductive connection of the first flex circuit, the first via disposed through at least a first portion of the touch screen, the conductive material of the first via being in direct contact with the conductive connection of the first flex circuit.
