  • Patent number: 11931993
    Abstract: A bonding method and a bonding device for a flexible panel. In the process of bonding a protective cover plate and the flexible panel, a heated-type optical adhesive is used, the optical adhesive at normal temperature has relatively low viscosity and the viscosity thereof is below a bondable threshold, so that before the flexible panel and the edge of the protective cover plate are bonded, the optical adhesive and the edge of the protective cover plate come into contact in advance and then can be effectively separated, thus poor bonding in a bending region is avoided, the risk of generating bubbles and cracks is small, and the bonding yield can be improved. Moreover, the optical adhesive is increased in viscosity after heated, thereby ensuring that the flexible panel is bonded to the protective cover plate.
