The formation of metal traces in the border areas of a touch sensor panel to provide improved reliability, better noise rejection, and lower manufacturing costs is disclosed. The metal traces can be coupled to rows on the touch sensor panel in an interleaved manner, so that any two successive rows can be coupled to metal traces in border areas on opposite sides of the touch sensor panel. In addition, by utilizing the full width available in the border areas in some embodiments, the metal traces can be formed from higher resistivity metal, which can reduce manufacturing costs and improve trace reliability. The wider traces can also provide better noise immunity from noise sources such as an LCD by providing a larger fixed-potential surface area and by more effectively coupling the drive lines to the fixed potential.
Conductive traces for routing a plurality of rows in a touch sensor panel to a single edge of the touch sensor panel, comprising:
A touch sensor panel comprising:
A mobile telephone including a touch sensor panel, the touch sensor panel comprising:
A digital media player including a touch sensor panel, the touch sensor panel comprising:
