Abstract

A method for producing a pane having an electrically conductive coating is described. The method includes applying an electrically conductive coating onto a substrate, identifying defects of the coating, focusing the radiation of a laser having an annular beam profile on the coating, wherein the annular beam profile surrounds the defect, and producing an annular de-coated region by simultaneously removing the coating in the region of the beam profile.
