  • 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.

  • Publication number: 20230020481
    Abstract: An embodiment of the present disclosure provides a display module, including a display panel: a cover plate on a light-emitting side of the display panel; and a heat dissipation layer on a back side of the display panel. The back side faces away from the light-emitting side. Edges of the cover plate, the display panel and the heat dissipation layer are bent toward the back side of the display panel to form a shape-matched arc surface. The display panel further includes a planar portion and edges surrounding the planar portion. At least part of an edge of an orthographic projection of the display module on a plane where the planar portion of the display panel is located is arc. The heat dissipation layer includes a stretchable structure in an arc surface region having an arc edge.

  • Publication number: 20220379357
    Abstract: A fabricating apparatus and method for a flexible display screen. The fabricating apparatus for the flexible display screen comprises a roller mechanism and a jig (21); the jig (21) has a bearing surface (211) for bearing a flexible display panel (1); the bearing surface (211) is a curved surface; the roller mechanism comprises a roller (31); and the axis (x) of the roller (31) is parallel to the plain line (y) of the bearing surface. The fabricating apparatus for the flexible display screen is used for attaching a support layer (2) to the flexible display panel (1), so that the flexible display panel (1) is better bonded to the support layer (2), thereby reducing the probability that the flexible display panel (1) is separated from the support layer (2) during normal use.
