  • 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: 20230156106
    Abstract: A display module includes a curved display panel and a curved cover plate that are attached by an adhesive, wherein at least one corner formed respectively by a cover plate body and a cover plate edge of the curved cover plate is a cambered corner. A thickness of a target structure at a target corner is greater than thicknesses of the target structure at other positions, the target structure being at least one of the cover plate edge and the adhesive, and a radius of curvature of the curved display panel is greater than a radius of curvature of a side, distal from the curved display panel, of the target structure.

  • 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.

  • Patent number: 7973506
    Abstract: The invention discloses a method for controlling a power car window lift. The method includes the following steps: detecting an operation state signal of the car window with a detection element; inputting the detection signal of the detection element into the controller; and the controller sending a control signal to an actuator, which controls the operation state of the car window lift. The main control element of the controller is a thyristor or an equivalent functional element. The car window lift's operation state signal includes a car window closed obstacle signal, a car window closed-in-place signal, a car window opened-in-place signal, and a car window opened obstacle signal. The invention further discloses a device for implementing the method for controlling the power car window.
