Claim:
1. A plastic film arrangement comprising: a plastic film; a touch module on the film comprising a plurality of conductors arranged in a coordinate system, the conductors being electrically insulated from each other, but capacitively coupled to crossover points forming a first matrix of conductors, and which points are located relative to one another either vertically and/or laterally or radially in the coordinate system; and an operating module on the film comprising further conductors forming a second matrix of conductors, the first and second matrix of conductors being combined to form a third matrix of conductors comprising the coordinate system, the operating module second matrix of conductors being electrically insulated from each other, but capacitively coupled to further crossover points in the second matrix, which first and second matrices of conductors are so connected to enable addressing of each crossover point from a corresponding conductor power source via a common connection; wherein the crossover points forming the third matrix are so located such that they divide the third matrix into at least two areas: a first area forming the touch module in which the crossover points are transparent and form the first matrix, which serves as a substructure for a multi-touch sensor and a second area forming the operating module in which the crossover points are arranged such that the third matrix is geometrically distorted in that a conductor is swapped out of the first matrix and which swapped out conductor is functionally replaced by a conductor in the second matrix; and wherein the conductors associated with the crossover points are electrically retained, wherein all of the conductors which form the third matrix are powered via the common connection.
