Display screen multi-channel OCR fitting and disassembling method

The invention discloses a multi-channel OCR laminating and disassembling method for a display screen, and relates to the technical field of display screen production. The display screen comprises an array substrate, a first optical transparent resin layer, a touch sensor, a second optical transparent resin layer and protective glass which are sequentially arranged. The disassembling method comprises the following steps: confirming a material layer A corresponding to a bad position, integrally disassembling other material layers B corresponding to one side of the material layer A, removing optical transparent resin attached to the outer side of the material layer A or other material layers B, and refilling a new optical transparent resin layer; and replacing the material layer A with a new material layer, and laminating the material layer B. According to the method, the original layer-by-layer disassembling process rule is broken through, the material on one side of the bad layer is directly and integrally dis
