laminating the anode substrate 110 and the coated aluminum foil 100 together the oled layer structure 120 is obtained in an exemplary embodiment the aluminum foil can be flexible and can be sealed on the backside for example with a polymer film in another exemplary embodiment the aluminum foil 130 is coated with the same organic layer 150 as the anode substrate 110 according to another embodiment only the first substrate 230 is coated as illustrated in fig3 the coated substrate 180 comprises an anode layer 220 at least one organic layer 210 and a cathode layer 200 and the second uncoated substrate 170 comprises an electrically conductive soft material after laminating the coated substrate 180 and the uncoated substrate 170 together the oled layer structure 190 is obtained in an exemplary embodiment the first and the substrate is rigid in another exemplary embodiment the first substrate is rigid and the second substrate is flexible or vice versa in still another exemplary embodiment the first and the second substrate is flexible the provided substrates may be transparent or opaque depending on the side of the oled that let pass the emitted light suitable substrates for example can be made from glass such as borosilicate glass or sodalime glass other suitable materials are.
