Electrically non-interfering printing for electronic devices having capacitive touch sensors

A method of manufacturing a capacitive sensor having visible graphic indicia for an electronic device, the method comprising the steps of:

• depositing a layer of semitransparent, electrically conductive material on a substrate;
• and
• selectively depositing, in a form of the visible graphic indicia, second layer of electrically conductive material on the substrate;
• wherein the second layer of electrically conductive material is electrically coupled to at least a portion of the layer of semitransparent, electrically conductive material;
• further wherein a combined material formed by the layer of semitransparent, electrically conductive material and the second layer of electrically conductive material has a greater reflectivity than does the layer of semitransparent, electrically conductive material.

A electronic device comprising a user interface for receiving a touch input, the user interface comprising:

• a cover layer;
• and
• a capacitive sensor layer disposed beneath the cover layer for detecting the touch input, the capacitive sensor layer comprising at least two types of capacitor sensor material, wherein a first type of capacitor sensor material is at least semitransparent and a second type of capacitor sensor material has a greater reflectivity than the first type of capacitor sensor material, wherein the at least two types of capacitor sensor material are electrically coupled together;
• further wherein the second type of capacitor sensor material is arranged as at least one graphic visible through the cover layer.
