Abstract: A touch sensor panel configured to detect objects touching the panel as well as objects that are at a varying proximity to the touch sensor panel. The touch sensor panel includes circuitry that can configure the panel in a mutual capacitance (near field) architecture or a self-capacitance (far field and super far field) architecture. The touch sensor panel can also include circuitry that works to minimize an effect that a parasitic capacitance can have on the ability of the touch sensor panel to reliably detect touch and proximity events.

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.
