First Claim
Patent Images
1. A touch-sensitive device comprising:
- a first visible light transparent substrate having a touch-interface surface and a display-interface surface, the touch-interface surface disposed toward touch input, and the display interface disposed toward the output of a display;
a second visible light transparent substrate having a first surface and a second surface and also having a touch sensing area comprised of an electrically conductive micropattern disposed on or in the second visible light transparent substrate, wherein the micropattern includes conductors with width between about 1 and 10 micrometers;
wherein the first surface of the second visible light transparent substrate is disposed toward the display-interface surface of the first visible light transparent substrate;
and wherein the first visible light transparent substrate includes a feature that reduces the visibility of the micropattern.
