▎ 摘　　要

NOVELTY - The method involves preparing a transparent colorless polyimide film as a substrate (101) for touch device manufacturing. The laser induction technology is used to prepare graphene channels (3010) around the first stacked film layer (3011) for electrical communication. The first stacked film layer and the second stacked film layer (3012) have the same thickness and constitute the stacked film layer of the substrate. The laser induction technology is used to fabricate a graphene pattern on the side of the stacked film layer away from the substrate to prepare a driving layer. The driving layer is used to drive the sensing layer to work. The screen printing technology is used to prepare circuit connection lines on the drive layer. The substrate, the sensing layer, the laminated film layer, the driving layer and the optical double-sided adhesive are sequentially combined to prepare a graphene touch device. USE - Method for preparing graphene touch device based on additive manufacturing technology. ADVANTAGE - The electrical connection between the sensing layer and the driving layer inside the graphene touch device is realized, which ensures the flexibility of the graphene touch device when ensuring the internal connection of the graphene film pattern electrical. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of a method for preparing graphene touch device based on additive manufacturing technology.
