Abstract:
A touch sensor panel including a plurality of drive lines crossing a plurality of sense lines, forming an array, is disclosed. The plurality of drive lines and the plurality of sense lines are formed by interconnecting a plurality of substantially transparent conductive sections having a first resistivity. A substantially transparent conductive material, with a second resistivity that is lower than the first resistivity, is deposited over at least part of at least one of the plurality of substantially transparent conductive sections of at least one of the plurality of drive lines and the plurality of sense lines. A second layer of the substantially transparent conductive material, with the second resistivity, can be deposited thereafter. At least one dummy section is disposed in an area of the touch sensor panel around the conductive sections of at least one of the plurality of drive lines and the plurality of sense lines.
