Abstract
A method for manufacturing a touch sensor includes the steps of: a) forming both a first touch conductive trail pattern (TCTP) and a first auxiliary conductive trail pattern (ACTP) on a first side of a dielectric substrate; and b) forming both a second TCTP and the second ACTP on a second side of the dielectric substrate, wherein each of the first and second ACTPs has micro auxiliary conductive units electrically disposed in an area range of the first and second TOTPs, and a shading rate of the micro auxiliary conductive units is below 1%. The first and second TCTPs and the first and second ACTPs jointly constitute a touch sensor. A sheet resistance of each of the first and second TCTPs is between 80 and 150 ohm/sq, and a sheet resistance of each of the first and second ACTPs is between 0.05 and 0.2 ohm/sq.
