Abstract
A multi-layer touch panel having an upper and a lower electrode that cross over one another. The electrode pattern for either electrode at the cross over area is complementary to the other electrode at the cross over area.
Claims30
A multi-layer touch panel, comprising:
- an upper electrode comprised of an interconnected upper mesh of micro-wire conductors;
- a lower electrode comprised of an interconnected lower mesh of micro-wire conductors;
- a dielectric disposed between the upper electrode and lower electrode;
- wherein the upper electrode crosses-over the lower electrode at a cross-over area, thus defining an upper electrode cross-over area having a first conductor pattern, and a lower electrode cross-over area having a second conductor pattern;
- wherein the first conductor pattern has a first variable active areal conductor density and the second conductor pattern has a second variable active areal conductor density;
- and,
- wherein the first and second variable active areal conductor densities are complementary to one another.

- an upper electrode comprised of an interconnected upper mesh of micro-wire conductors;
- a lower electrode comprised of an interconnected lower mesh of micro-wire conductors;
- a dielectric disposed between the upper electrode and lower electrode;
- wherein the upper electrode crosses-over the lower electrode at a cross-over area, thus defining an upper electrode cross-over area having a first conductor pattern, and a lower electrode cross-over area having a second conductor pattern;
- wherein the first conductor pattern has a uniform active areal conductor density and the second conductor pattern has a variable active areal conductor density;
- and,
- wherein at least a portion of the second conductor pattern has a higher active areal conductor density than the active areal conductor density of the first conductor pattern.
