Abstract: A layer electrode for touchscreens, in particular one which is suitable for the construction of capacitive touchscreens, wherein the detection accuracy of the touchscreen is virtually independent of an increase in the number of electrode arrays in the touchscreen. This is achieved in that, within the transparent field of view of the touchscreen, conductivity centres are formed through first electrode arrays which are connected directly to supply lines into the edge region and to a controller.

This capacitive sensor element comprises at least one multilayer body made up of two structured electrically conductive layers and an insulating layer in between. The invention provides a layout with redundant conductive strips for an arrangement of crossing conductive strips, through which the requirement for register accuracy in the two-layer lamination of layer electrodes is reduced, in particular with respect to connecting the connections to the plugs in the edge area of a module using a corresponding sensor element.

In particular, the invention relates to a method for the back-injection molding of layer electrodes (1) for producing touch-sensitive sensors for example for touch screens. Parts of the layer electrode (1), which after the back-injection molding should still be able to move freely, are covered by a sacrificial film (3) before and during the back-injection molding.

Abstract: The invention relates to a layer electrode for touchscreens, in particular one which is suitable for the construction of capacitive touchscreens. In the case of a growing number of pixels within the layer electrode, various possibilities are proposed for reducing the loss of surface area within an outer electrode array due to the passage of supply lines to inner electrode arrays. For this it is proposed to change the shape of the electrode arrays, the shape of the galvanic isolations between the electrode arrays and finally the arrangement of the supply lines for the electrode arrays.

In each information area a first zone (10) with electrically conductive material is provided, over the entirety of which electrically conductive material is conductively connected to it. In each background area a plurality of second zones with electrically conductive material is provided, which are galvanically separated from each other. Each first zone (10) preferably occupies a surface area that is at least five times larger than each of the second zones. The electrically conductive material is preferably provided with an average surface coverage which varies over all information areas and background areas (18) by less than 25%.

Abstract: A body (1, 1?, 1?) produced by an in-mold process has a first film (2, 2?, 2?) with at least one electrical or electronic functional layer (25). In a functional area (20a, 20a?, 20a?) of this functional layer, at least one electrical or electronic component is provided, and at least one electrical connection for this is provided in a contact area (20b, 20b?, 20b?). The first film is partially back-injection molded with a plastic main material (3, 3?, 3?) such that the contact area (20b, 20b?, 20b?) is at least partially free from this plastic main material (3). Suitable formation of the first film (2, 2?, 2?) guarantees that a tab (F) separated from the plastic main material (3, 3?, 3?) is provided which adjoins a back-injection molded part of the first film in an area of surface (20c, 20c?, 20c?) of the body which is at a distance from an edge (31, 31?) of the body delimiting the surface (30) with the first film.

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 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.

Abstract: Disclosed is a plastic film and to a touch module produced therefrom. The module is constructed from two conductive layers with an insulation layer in between, as are used in capacitive touch pads and/or touch screens, for example. The problem of connecting the respective x or y sensors across two planes in a cost-effective manner employs foldable sensor planes in the plastic film suitable for mass production. The connections and conductor tracks are concentrated on one plane on a sensor side wherein the sensor planes are arranged on flexible materials. The registering of the two planes relative to each other is simplified via a secure mechanical connection of the two planes via a fold in the film.

Abstract: In a multi-layer body with a carrier and at least one conduction layer first areas and second areas are galvanically isolated from each other by third areas. In the third area sections are omitted from conductor traces and replaced by replacement pieces. The multi-layer body thereby has an optically homogeneous effect (e.g. is uniformly transparent or uniformly reflective).

Abstract: Transparent electrically conductive functional layer, production process and use thereof. The invention concerns a transparent electrically conductive functional layer, in particular a laminate body. The invention makes it possible for the first time to produce thin conductive functional layers for use in resistive touch screens, for example in a printing process. By way of example with a coverage of 5% and adequate conductivity the functional layer still works at 95% transparent for the human eye.

Abstract: A touchpad apparatus extends, without having to be covered by a cover, up to an outer housing edge of an operating device. In two possible cases, not only touchpads and connections between the touchpads in the touchpad area are formed by patterns of conductive strips which cannot be resolved by the human eye, but also contact connection lines which connect contact elements to each other at two sides of the touchpad area.
