Narrow Border for Capacitive Touch Panels
First Claim
1. A capacitive touch screen panel, comprising:
- a first transparent substrate that includes a first conductive layer disposed adjacent to a surface thereof;
a second transparent substrate that includes a second conductive layer disposed adjacent to a surface thereof;
a first set of conductive traces disposed on the first transparent substrate and in conductive communication with the first conductive layer; and
a second set of conductive traces disposed on the second transparent substrate and in conductive communication with the second conductive layer, wherein at least one of the first set of conductive traces and the second set of conductive traces are deposited by one of electro deposition and vacuum deposition.

Abstract
A touch screen sensor assembly and associated method for manufacturing the touch screen sensor assembly are provided. The touch screen assembly includes one or more transparent substrates that are arranged above a display. Each of the transparent substrates may include a conductive layer that is disposed adjacent to a surface of a corresponding one of the substrates. In addition, a set of conductive traces may be disposed on each of the transparent substrates and in conductive communication with the corresponding conductive layer. At least one of the sets of conductive traces may be deposited using electro deposition or vacuum deposition techniques so as to reduce a width of each trace, thereby reducing the size of a non-transparent border that surrounds the transparent substrates, maximizing the available portion of the transparent substrates for use in touch sensing.
