Claim:
1. An integrally-formed capacitive touch panel, comprising: a singular lens substrate made of glass, said singular lens substrate having a top surface for receiving physical tactile input and a bottom surface; a mask layer formed on a periphery of said singular lens substrate; and a sensing circuit integrally coupled with said bottom surface of said singular lens substrate, wherein: said sensing circuit and said mask layer are integrally formed on said bottom surface of said singular lens substrate, a first part of said sensing circuit is covered by said mask layer, a second part of said sensing circuit that is not covered by said mask layer forms a sensing region, and said sensing circuit comprises: a first sensing circuit; an insulation layer; and a second sensing circuit, wherein: said singular lens substrate, said mask layer, said first sensing circuit, said insulation layer, and said second sensing circuit are integrally formed, said insulation layer is only present in one or more areas where said first sensing circuit and said second sensing circuit overlap to prevent contact of said first sensing circuit and said second sensing circuit, there is no other substrate laminated or bonded to said singular lens substrate of said integrally-formed capacitive touch panel, said first sensing circuit comprises a first conductive electrode and a first metal trace, said second sensing circuit comprises a second conductive electrode and a second metal trace, and said first conductive electrode and said second conductive electrode are made of transparent material and located in said sensing region.
