Summary:Abstract The formation of metal traces (102,104) in the border areas (106,108) of a touch sensor panel (110) to provide improved reliability, better noise rejection, and lower manufacturing costs is disclosed. The metal traces (102,104) can be coupled to rows (100) on the touch sensor panel (110) 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.
