Abstract
An input device having a plurality of low-visibility sensor electrodes and method for fabricating the same are provided. In one embodiment, an input device includes a plurality of sensor electrodes disposed over a display device. A first sensor electrode of the plurality of sensor electrodes includes a conductive mesh having a first periodicity defined by intersections of conductive traces forming the mesh. A terminal portion of one of the conductive traces terminating at an edge of the first sensor electrode has an orientation that is different than an orientation of a corresponding portion of the mesh defining the first periodicity. An end of the terminal portion proximate the edge laying over a subpixel has the same color as a subpixel of the display device which the end would lay over if the end had the same orientation as the corresponding portion of the mesh defining the first periodicity.
