A plastic film touch sensor, use of the plastic film and method of making a multimodal input device

摘要

The invention relates to a plastic film for a multimodal input device, in particular one that links a touch module and a control element. For example, such input devices are found in the center consoles of automobiles, in dishwashers or washing machines, telephones or the like. For example, such input devices are found in the center consoles of automobiles, in dishwashers or washing machines, telephones or the like. The invention shows for the first time how touch modules on the one hand and control modules on the other hand can be connected by means of the layout of the conductors in the form of a geometrically distorted matrix on a single plastic film forming a carrier for a combined input device. For this purpose, printed conductors are outsourced in the edge region of the printed conductor matrix of the touch module and connected to the operating elements. This creates a geometrically distorted matrix of conductors on the plastic film.
