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.
