Problems solved by technology

The superposition of sufficiently precise grid structures suitable for eliminating the moiré effect can only be realized at enormous cost, which is not economical, since even the smallest differences between the superimposed grid structures, such as for example a difference of only 10 μm, lead to moiré effects. Hall effect

Embodiment Construction

[0083] figure 1 Two basic possible ways of implementing a capacitive or resistive two-piece touch screen are shown. first, figure 1 a shows the realization of a structure of rows and columns of conductor path segments (strips and strips), where sensors such as receivers are represented by thicker and darker conductor path segments arranged horizontally and transmitters such as by vertically running Thinner segment representation. The present invention solves the problem of figure 2 c and image 3 The illustrated prior art creates problems in the intersection area due to the layer construction with the respective grid structure.

[0084] figure 1b shows a so-called diamond-shaped structure, where for example the transmitter is again represented by a diamond-shaped or diamond-shaped structure shown horizontally and deeper, and at the second higher level the receiver is shallower and arranged so that the terminal contacts are rotated by 90° . Here, the problem of overla...

Abstract

The invention relates to a layered body, in particular a layered body with two electrically functional layers, and to the use of the layered body, for example in a touch screen with improved resolution. By changing the grid structure at the intersection area, the moiré effect caused by pattern superposition can be avoided.

Description

technical field [0001] The invention relates to a layered body, in particular a layered body with two electrically conductive functional layers, as well as a production method and the use of the layered body, for example in a touch screen with improved resolution. Background technique [0002] An electrical functional layer is known from DE 10 2009 014 757 in which electrically conductive non-transparent paths are arranged on the surface of a transparent support, patterned in such a way that the functional layer is transparent to the human eye and electrically conductive. [0003] A disadvantage of layered bodies with only one electrically functional layer is that detection is possible here only in one direction. There is therefore a need for layered bodies which already combine two electrically functional layers, for example stacked at angles ranging from 85° to 95° in the layer structure. [0004] The use of a grid structure involves varying degrees of absorption or brigh...
