Coating system and method

Abstract

A coating system and a coating method. The coating system includes: a first detector, a second detector, a control device, and a deviation correction device, where the first detector is configured to detect first coating information of a first surface of a substrate; the second detector is configured to detect second coating information of a second surface of the substrate, the first surface being one surface of the substrate, and the second surface being the other surface of the substrate; the control device is configured to calculate a deviation value for both sides of the first surface and the second surface according to the first coating information and the second coating information, and send a deviation correction instruction to the deviation correction device according to the deviation value; and the deviation correction device is configured to perform coating deviation correction on the substrate according to the deviation correction instruction.
