Abstract

Embodiments relate to a coating system. A substrate includes a first coating region and a second coating region adjacent to the first coating region. The coating system includes a first gravure mechanism and a second gravure mechanism, where the first gravure mechanism is configured to apply a first functional layer onto the first coating region, and the second gravure mechanism can receive the substrate having the first functional layer and apply a second functional layer made of a material different from that of the first functional layer onto the second coating region. In the coating system, with provision of first gravure mechanism and the second gravure mechanism, when the substrate is continuously transported in a same direction, the two functional layers made of different materials can be sequentially applied onto corresponding regions of the substrate.
