Abstract

An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous area and to include interior regions that are electrically discontinuous. The electrically continuous area may be patterned according to a one pattern, and the interior pattern may be patterned according to another pattern.

First claim

The invention claimed is:

1. A touch screen sensor, comprising:
an upper electrode layer comprising an array of composite electrodes comprised of a plurality of continuous micro-wire conductors disposed in a first pattern;
a lower electrode layer comprising a plurality of electrodes;
wherein the upper and lower electrodes are separated by a dielectric layer, and together define an electrode matrix having nodes where the upper and lower electrodes cross over;
wherein the comp…
