Abstract

The invention discloses a method for preparing a stretchable electronic device with a regular wrinkle structure, which belongs to the field of optoelectronic technology. The invention uses mechanical processing, 3D printing or injection molding to prepare a roller with a strip-shaped microstructure on the surface. Plating technology vapor-deposits a metal film on the surface of the elastic film as a metal spacer layer, and finally uses a roller rolling process to paste the flexible thin film electronic device on the surface of the elastic film to prepare a stretchable electronic device with a regular wrinkled structure. The preparation method of the stretchable electronic device with regular wrinkle structure proposed by the present invention is suitable for flexible thin film electronic devices with different materials, thicknesses and functions, the wrinkle shape is controllable, the preparation cost is low, the speed is fast, and the production The efficiency is high, and the performance of the device is uniform and stable, so it is more suitable for commercial production.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and specifically relates to a method for preparing a stretchable electronic device with a regular wrinkled structure, using a roller wheel with a microstructure on the surface to control the combination of an ultra-thin flexible electronic device and an elastic film to form a regular wrinkled structure, Furthermore, the problem of incompatibility between the preparation process and device performance encountered in the large-scale production and commercial application of stretchable electronic devices based on wrinkled structures is solved. Background technique [0002] In recent years, with the development of the electronics industry, stretchable electronic devices have gradually entered people's field of vision. Compared with traditional devices based on hard materials such as silicon and glass, stretchable electronic devices are flexible, bendable and stretchable, so they are suitable ...
