Abstract

Disclosed is a plastic film and to a touch module produced therefrom. The module is constructed from two conductive layers with an insulation layer in between, as are used in capacitive touch pads and/or touch screens, for example. The problem of connecting the respective x or y sensors across two planes in a cost-effective manner employs foldable sensor planes in the plastic film suitable for mass production. The connections and conductor tracks are concentrated on one plane on a sensor side wherein the sensor planes are arranged on flexible materials. The registering of the two planes relative to each other is simplified via a secure mechanical connection of the two planes via a fold in the film.
