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.

Layer electrode for touch screen

The invention relates to a capacitive sensor element with a plurality of sensor fields, as they correspond for example to the arrangement on a touch screen. 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.

Capacitive sensor element and method for the production thereof

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.

Layer electrode for touchscreens

A film () which has at least one electric or electronic functional layer (), wherein at least one electric and/or electronic component is provided in a functional area of the functional layer (), and wherein at least one electrical connection is provided in a contact area of the at least one functional layer (), which electrical contact is galvanically coupled to at least one component, wherein the film () has a contact flap which provides at least one part of the contact area ('), has a further layer (&#x2033;), in a thickness of at least 300 nm and preferably at least 1 &#x3bc;m, particularly preferably of at least 7 &#x3bc;m, on the functional layer () at least in a transition area () between the functional area () and the contact area (), which comprises at least a partial area of the contact flap. Alternatively, in a transition area the flap can taper away from the functional area.

Film and body with such a film

A multilayer body with a carrier and a layer arranged thereon which comprises electrically conductive material in such an arrangement comprises an information area and a background area () which are galvanically separated from each other. In each information area a first zone () 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 () 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 () by less than 25%. A homogeneous appearance of the multilayer body is thereby ensured, and an item of information provided in the information area, provided by the shape, size and/or alignment of the first zone, is not visible without aids, and therefore cannot be copied.

Capacitively readable encoded multilayer body

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).

Multi-layer body

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.

Multilayer body forming display apparatus touchpad

A multi-layer body for providing a touch panel functionality has a plurality of areas of surface which have a different size defined by corresponding electrically conductive elements; in particular, larger areas of surface are arranged more in a central area of the entirety of the area of surface and smaller areas of surface are arranged more further toward an edge of the body.
