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.
Claims21
A method for producing a pane having an electrically conductive coating, comprising:
- applying an electrically conductive coating on a substrate;
- identifying a defect of the electrically conductive coating;
- focusing radiation from a laser with an annular beam profile on the electrically conductive coating, wherein the annular beam profile surrounds the defect;
- and
- producing an annular de-coated region by simultaneously removing the electrically conductive coating in the region of the beam profile.
A glass pane having an electrically conductive coating, comprising:
- a glass pane;
- an electrically conductive coating on the glass pane;
- and
- a defect in the electrically conductive coating,
- wherein the defect is isolated from the surrounding coating using radiation from a laser having an annular beam profile.
A method of using a glass pane having an electrically conductive coating, comprising:
- providing a glass pane having an electrically conductive coating with a defect, wherein the defect is isolated from the surrounding coating using radiation from a laser having an annular beam profile;
- and
- using the glass pane having an electrically conductive coating as a heatable window glass pane of a building or of a motor vehicle, or as a component of a glazing with electrically switchable or controllable optical properties.
A pane having an electrically conductive coating, comprising:
- a substrate containing at least one polymer;
- an electrically conductive coating on the substrate;
- and
- a defect in the electrically conductive coating,
- wherein the defect is isolated from the surrounding coating using radiation from a laser having an annular beam profile.
