Problems solved by technology

[0003] The disadvantage of the known ITO electrical functional layers is that the material is very expensive if the transparency or conductivity can be optimized
Furthermore, a resistive touch screen with a conventional ITO layer can only achieve "single touch" functionality, that is, only x and y coordinates can be detected forever, because the control unit can only ever handle one signal or position

Embodiment Construction

[0049] Figure 1a and 1b An example of a pattern of conductive tracks 1 on a transparent carrier (not visible since it is transparent) is shown.

[0050] Figure 2a and 2b An example of a pattern similar to Figure 1 is shown, but here the conductive traces are not parallel to each other to avoid waviness.

[0051] image 3 A cross-sectional view is shown with a transparent substrate 2, which is a transparent film (as is usual for substrates), but it could also be a transparent conductive layer of suitable thickness. A pattern of conductive traces 1 is disposed thereon.

[0052] Figure 4 shown with image 3 The same cross-sectional view, but with an additional transparent thin layer 3 and another additional layer 4 on the rear side of the substrate 2 in addition to the conductive tracks 1 and the substrate 2, where layer 3 is provided with respect to a conventional substrate Surface conductivity, layer 4 is, for example, an antireflection layer.

Abstract

The invention relates to a transparent electrically conductive functional layer, especially a layered body. The invention enables, for the first time, the production of thin conductive functional layers for use in resistive touch screens, for example during the touching process. For example, the functional layer is effective with a 5 % covering of conductive segments and sufficient conductivity up to 95 % transparency to the human eye.

Description

technical field [0001] The present invention relates to an electrical functional layer, in particular to a laminated body, its manufacturing method and use. Background technique [0002] The production of resistive touchscreens controlled by sensor means requires transparent, conductive and possibly structured functional layers, which until now were formed from transparent ITO (indium tin oxide). In the case of a resistive touch screen, two conductive layers arranged oppositely form contact (contact at a given position) by pressing, and the pressed point is identified by determining the resistance. Since touch screens are always associated with stored images (displays and / or images), high transparency and conductivity sufficient to determine the point of pressure are required. Hitherto, these laminates have been formed of ITO, for example, on a plastic film. [0003] The known electrical functional layers of ITO have the disadvantage that the material is very expensive if ...
