| 摘要 |
The present invention relates to a method for the production of a combined piezo/luminescent film for use as actuating element, especially in vehicles, comprising the steps: provision of a film-type base material (1); application of a piezoelectric varnish (2) onto the base material at least in a first partial area (A1, A2) so as to form a piezoelectric switch surface in the first partial area; application of a luminescent varnish (3) onto the base material in at least a second partial area (B1, B2) so as to be able to illuminate the switch surface in the second partial area; covering at least of the first and second partial area with a top layer (4) that is bonded to the base material. In addition, the present invention describes an actuating element with a combined piezo/luminescent film produced in such a manner.
