preparation example Construction

[0050] A preparation method of a soft-pressed packaging structure of a flexible device with an island bridge structure, the soft-pressed packaging structure comprises a packaging film 1, a flexible device 2 and an elastic layer 3, the flexible device 2 is an island-bridge structure with functional units, and the packaging film 1 is covered on both sides of the flexible device 2 and conformed to the surface shape of the flexible device 2, and the elastic layer 3 connects the packaging film 1 and the flexible device 2 and fixes the shape of the packaging film 1; the preparation method includes the following steps:

[0051] S1, covering a packaging film 1 on one side of the flexible device 2;

[0052] S2, bonding the packaging film 1 and the flexible device 2 through the elastic layer 3;

[0053] S3, covering the other side of the flexible device 2 with another packaging film 1;

[0054] S4 , making the encapsulation film 1 conform to the surface of the flexible device 2 .

Abstract

The invention relates to the field of packaging of flexible electronic devices, in particular to a soft pressing packaging structure of an island bridge structure flexible device, which is characterized in that two surfaces of the flexible device are respectively covered with a packaging film, and the packaging films are conformally attached to the surface of the flexible device; an elastic layer is formed in a gap between the packaging film and the flexible device, and the flexible device is bonded with the packaging film through the elastic layer. The soft pressure packaging structure is low in cost and simple in preparation method, the packaging film is in conformal fit with the surface of the flexible device, and meanwhile, the gap between the packaging film and the flexible device is filled with the elastic layer, so that the robustness of the device is effectively guaranteed, the thickness of the bridge part is not greatly increased, the concave-convex configuration of the island bridge structure is kept to a great extent, and the reliability of the device is improved. The packaged island bridge structure device still has high flexibility and stretchability, and can be well attached to various complex surfaces in a conformal mode. The invention also relates to a preparation method of the soft pressing packaging structure of the island bridge structure flexible device.

Description

technical field [0001] The invention relates to the packaging field of flexible electronic devices, in particular to a soft-pressed packaging structure of a flexible device with an island bridge structure. The invention also relates to a preparation method of a soft-pressed packaging structure of a flexible device with an island bridge structure. Background technique [0002] Through the selection of materials and the design of the structure, flexible electronic devices have excellent flexibility and stretchability while realizing the functions of traditional rigid electronic devices, and can be attached to the surface of human skin or other organs with complex and large dynamic deformation. has gained a lot of attention in recent years. A commonly used design strategy for flexible electronic devices is to use island-bridge structures to integrate rigid electronic devices and flexible circuits. The island-bridge structure consists of a non-deformable "island" and a stretch...
