  • Patent number: 11701876
    Abstract: The present invention provides a lamination method for a special-shaped glass cover plate, including following steps. Step S1: forming a magnetic layer on a display panel. Step S2: arranging a first solenoid and a second solenoid at a regular-shaped portion and a special-shaped portion of the special-shaped glass cover plate, respectively. Step S3: supplying opposite electric currents to the first solenoid and the second solenoid. Step S4: changing magnitude of an electric current from the regular-shaped portion to the special-shaped portion. Step S5: when to attach the display panel to the special-shaped portion of the special-shaped glass cover plate, changing magnitude of the electric current of the second solenoid and a direction of the second solenoid to attach the display panel along the special-shaped portion.

  • Patent number: 11588131
    Abstract: The present application discloses a display panel and a display device. The display panel includes a display area and a non-display area; the non-display area includes a bonding area away from the display area, and a plurality of terminals are disposed in the bonding area; and the non-display area further includes an anti-overflow portion disposed around the plurality of terminals. The present application prevents the problem of ACF overflow by disposing the anti-overflow portion around the plurality of terminals in the non-display area, such that the peeling of the glass substrate is facilitated, and the yield of the product is improved.

  • Patent number: 11269379
    Abstract: A display screen assembly and a display device are disclosed. The display screen assembly includes a cover and a flexible display panel disposed in a stack arrangement. The cover is configured with peripheral edges bending toward the flexible display panel. The flexible display panel includes a first plane, a curved surface disposed around the first plane, and a second plane adjoining the curved surface. The curved surface includes a first curved surface and a second curved surface. The first curved surface bends and extends from peripheral edges of the first plane in a direction where the peripheral edges of the cover bend, and the second curved surface bends and extends from peripheral edges of the first curved surface with a predetermined radius in a direction toward the first plane.
