A substantially transparent mutual-capacitance touch sensor panel 300 has sensors fabricated on a single side of a substrate for detecting multi-touch events. Substantially transparent row and column traces 302, 304 can be formed on the same side of the substrate, separated by a thin dielectric material, using diamond, rectangular, or hexagonal rows and columns. The row and column traces form an array of sensors each centered where the first and second traces cross. Dummy shapes 320, 322 of the same material as the row and column traces are formed alongside the rows and columns to substantially cover the top side of the substrate with a uniform stack of material providing optical uniformity. Metal traces in the border areas can also be formed on the same side of the substrate as the rows and columns and allow both the rows and columns to be routed to a small flex circuit bonded to only one side of the substrate. |
