CAPACITIVE SWITCH SENSORS ON DECORATIVE IN-MOLD FILMS BACKGROUND

摘要

This invention is related to process for the production of a interior trim piece, comprising the steps of:—providing a film layer—applying conductive ink/paint to the back surface of the film layer to provide a circuit path and—attaching a substrate on the back surface of the film layer. This invention further relates to a interior trim piece comprising a film layer with a circuit path on its back surface, whereas the circuit path is made from conductive ink/paint.
