Plastic Film having Lines for a Multi-Modal Input Device and Method for Producing
First Claim
1. A plastic film comprising:
- a plastic film;
a plurality of conductors on the film electrically insulated from each other, but capacitively coupled to crossover points forming an electrical matrix, and which points are formed either vertically and/or laterally, on one or on two planes;
wherein the crossover points forming the matrix divide the matrix into at least two areas;
a first area in which the crossover points are transparent and form a homogeneous matrix which serves as a substructure for a multi-touch sensor and a second area in which the crossover points are arranged such that the matrix is geometrically distorted but electrically retained, wherein all of the conductors form the electrical matrix which is powered via a connection to the matrix.

Abstract
A plastic film for a multi-modal input device has conductors that link a touch module and an operating element. Such input devices, for example, are in central consoles of motor vehicles, dishwashers, washing machines, telephones, or the like. Touch modules and operating element modules are interconnected by the layout of conductors in the form of a geometrically distorted electrical matrix on a single plastic film which forms a carrier for a combined input device. The conductors are electrically insulated from each other, but capacitively coupled to crossover points in the electrical matrix, the crossover points dividing the matrix into at least two areas. Strip conductors extend from the matrix at an edge area of the matrix of the touch module and connected to the operating elements forming a geometrically distorted matrix of conductors on the plastic film.
