[0049] In order to more clearly illustrate the present invention, the present invention will be further described below in conjunction with the embodiments and drawings. Similar components in the drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following specific description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0050] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not indicate any order, quantity, or importance, but are merely used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. "Include" or "comprising" and similar words mean that the elements or objects that appear before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0052] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] In the description of the embodiments of the present disclosure, the orientations or positional relationships indicated by technical terms such as "center" and "edge" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present disclosure.

[0054] The bonding of a double-curved surface not only causes bending deformation in the normal direction of the arc, but also stretching in the tangential direction of the arc, resulting in stretching deformation, such as arc-shaped watches, spherical displays, and "four-sided curved" waterfall screen displays. The inventors found that under normal circumstances, the amount of stretching required in the tangential direction is L = [θ-2sin(θ / 2)]R, where θ is the curvature of the arc and R is the radius of curvature of the arc. If the deformable variable of the bonded flexible panel is greater than or equal to L, a conformable bonding surface can be formed; in extreme cases, if the deformable variable of the bonded display device is 0, a bubble of size L will be generated. Therefore, when designing a display device with a double curvature shape, the curvature θ and the radius of curvature R are both key factors.

[0055] In some embodiments, the flexible panel needs to be first bonded to a silicone profiling jig corresponding to the curved cover plate, and then the silicone profiling jig is controlled to move upward in a vacuum environment to bond the flexible panel to the curved cover plate. However, this bonding method cannot allow the flexible panel to deform evenly and allow the joints of the flexible panel to fit tightly, and the problem of false bonding bubbles is prone to occur. Due to uneven deformation, local excessive stretching causes display failure or local accumulation and extrusion causes wrinkle deformation. In order to make the flexible panel fit the curved cover plate, the deformation of the flexible panel needs to occur evenly, and the bonding area needs to be precisely controlled so that it deforms in segments.

[0056] Based on the above considerations, an embodiment of the present application provides a bonding device and a bonding method for bonding a flexible panel to a curved cover plate, using segmented pressurization to precisely control the bonding position, allowing the flexible panel to undergo uniform deformation during the curved bonding process, and at the same time making the flexible panel tightly bonded to the curved cover plate at the connection point, thereby avoiding bubbles generated by the tight pressing ratio.
