Abstract:
An input device having a plurality of low-visibility sensor electrodes and method for fabricating the same are provided. In one example, an input device includes a display device having an array of pixels and a plurality of sensor electrodes disposed on a viewing side of the display device. At least a first sensor electrode of the plurality of sensor electrodes includes a plurality of spaced apart conductive traces forming a conductive mesh, wherein mesh having a first periodicity defined by intersections of the conductive traces forming the mesh. A terminal portion of one of the conductive traces terminates at an edge of the first sensor electrode and has an attached light occluding element. The attached light occluding element is disposed over a subpixel having the same color as a subpixel which an intersecting trace would lay over when the intersection occurs in an interior region of the sensor electrode.
