Mesh sensor design for reduced visibility in touch screen devices

摘要

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.

1. An input device comprising:
a display device having an array of pixels, each pixel comprising at least a first subpixel having a first color and a second subpixel having a second color that is different than the first color; and a plurality of sensor electrodes disposed on a viewing side of the display device and configured to sense objects in a sensing region of the input device, wherein at least a first sensor electrode of the plurality of sensor electrodes further comprises:
a plurality of spaced apart conductive traces forming a conductive mesh having a first periodicity defined by intersections of the conductive traces forming the mesh;a terminal portion of one of the conductive traces terminating at an edge of the first sensor electrode having an attached light occluding elementwherein 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.
