TOUCH SCREEN STACK-UPS
First Claim
1. A multi-touch sensor panel, comprising:
- a first subassembly having a front side capable of being touched, and a back side opposite the front side;
a plurality of first traces of a first substantially transparent conductive material formed on the back side of the first subassembly;
a plurality of second traces of a second substantially transparent conductive material;
a dielectric material formed between the first traces and the second traces, the dielectric material being distinct from any adhesive layer;
a passivation layer disposed at least over the plurality of second traces; and
an adhesive disposed over the passivation layers, the adhesive begin distinct from the substrate;
wherein the second and first traces are oriented to cross over each other at crossover locations separated by the dielectric material, the crossover locations forming mutual capacitance sensors for detecting one or more touches on the front side of the first subassembly.

Abstract
A multi-touch sensor panel is disclosed that can include a glass subassembly having a plurality of column traces of substantially transparent conductive material that can be formed on the back side, wherein the glass subassembly can also act as a cover that can be touched on the front side. Row traces of the same or different substantially transparent conductive material can then be located near the column traces, and a layer of dielectric material can be coupled between the column traces and the row traces. The row and column traces can be oriented to cross over each other at crossover locations separated by the dielectric material, and the crossover locations can form mutual capacitance sensors for detecting one or more touches on the front side of the glass subassembly.
