Optical-band visibility for touch-sensor mesh designs
First Claim
1. An apparatus that comprises:
- a touch sensor that comprises a mesh of conductive material configured to extend across a display, wherein;
the mesh comprises first lines of conductive material that are substantially parallel to each other and second lines of conductive material that are substantially parallel to each other;
the first lines extend across the display at a first angle relative to a first axis;
the second lines extend across the display at a second angle relative to the first axis;
first lines that are adjacent to each other are separated from each other along the first axis by a first separation distance;
second lines that are adjacent to each other are separated from each other along the first axis by a second separation distance;
the first and second angles of the first and second lines and the first and second separation distances of adjacent ones of the first and second lines collectively form optical bands with respect to the display that have an optical-band visibility that is a product of an optical-band contrast function and an optical-band frequency function;
the optical-band contrast function is

Abstract
In one embodiment, an apparatus includes a touch sensor that includes a mesh of conductive material configured to extend across a display. The mesh includes first lines of conductive material that are substantially parallel to each other and second lines of conductive material that are substantially parallel to each other. The first lines extend across the display at a first angle relative to a first axis, and the second lines extend across the display at a second angle relative to the first axis. First lines that are adjacent to each other are separated from each other along the first axis by a first separation distance, and second lines that are adjacent to each other are separated from each other along the first axis by a second separation distance.
