Claim 14:
15. A coating system for coating a substrate, the coating system comprising:
a first gravure apparatus configured to receive a substrate, wherein a surface of the substrate comprises two first coating regions and four second coating regions, the four second coating regions comprises two outer second coating regions and two inner second coating regions, each one of the two first coating regions have two edges respectively adjacent to one of the outer second coating regions and one of the inner second coating regions, the first and second coating regions are not overlapped, wherein the first gravure apparatus comprises a first gravure roller, the first gravure roller comprises a first roller body, a surface of the first roller body comprises two first engraving regions respectively corresponding to the two first coating regions, each one of the first engraving regions and the corresponding first coating region have an equal width, and the first gravure apparatus is configured to apply a first functional layer onto the two first coating regions; and
a second gravure apparatus arranged in a transporting direction of the substrate downstream from the first gravure apparatus and configured to receive the substrate having the first functional layer coated on the two first coating regions, wherein the second gravure apparatus comprises a second gravure roller, the second gravure roller comprises a second roller body, a surface of the second roller body comprises four second engraving regions respectively corresponding to the four second coating regions, each one of the four second engraving regions and the corresponding second coating region have an equal width, wherein the second gravure apparatus is configured to apply a second functional layer made of a material different from a material of the first functional layer onto the four second coating regions.
