Curved display devices refer to display devices with curved edges or curved fronts, including laminated curved cover plates and flexible display panels. It is currently widely used in the field of vehicle-mounted displays and various small household appliances. The surface of a curved display device can be in a variety of curved shapes, such as S-shaped, C-shaped, L-shaped, etc. In the related art, when laminating the curved cover plate and the flexible display panel of a curved display device, the flexible display panel is usually placed on a carrier film, and the curved cover plate is pressed down by a laminating jig to complete the lamination of the curved cover plate and the flexible display panel.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In the embodiments of the present invention, words such as "first", "second", "third", and "fourth" are used to distinguish between identical or similar items with substantially the same functions and effects. This is only for the purpose of clearly describing the technical solutions of the embodiments of the present invention and shall not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0048] In the embodiments of the present invention, “plurality” means two or more than two, and “at least one” means one or more than one, unless otherwise clearly and specifically defined.

[0049] In the embodiments of the present invention, the orientation or position relationship indicated by the terms "upper" and "lower" is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

During the bonding process, the display substrate 20 is first placed on the base, the clips 70 on both sides clamp the carrier film 60, and the carrier film 60 has a certain tension, then the flexible display panel 30 is placed on the carrier film 60, the glass cover plate 10 is fixed to the cover plate jig 40, and the bonding surface of the glass cover plate 10 is pressed down toward the bonding direction F of the flexible display panel 30, so that the flexible display panel 30 is deformed by force during the pressing process, and finally the flexible display panel 30 and the glass cover plate 10 are bonded together. During the bonding process between the flexible display panel 30 and the glass cover plate 10 , since the flexible display panel 30 will be subjected to a certain deformation force, the supporting film 60 will also be subjected to a downward force, which will cause the supporting film 60 to be unable to be placed stably, and easily cause bubbles to be generated between the flexible display panel 30 and the glass cover plate 10 .
