Curved surface electrochromic transparent device with high efficiency and uniform color change and its preparation method

Abstract

The invention relates to a curved surface electrochromic transparent device with high efficiency and uniform discoloration and a preparation method thereof. Clean with water; enter the vacuum chamber, and under vacuum, plate various transparent film layers on the surface of the first substrate and the second substrate; under the condition of satisfying the normal operation of the circuit, it can be electrochromic and transparent on the curved surface with high efficiency and uniform discoloration Within the visible area of ​​the device, multiple conductive channels are correspondingly designed on various transparent film layers; transparent conductive strips are correspondingly extended inside the multiple conductive channels. In the present invention, the uniformity of the film thickness is realized by reasonably setting the sputtering process parameters and controlling the gradient change of the running speed from one side edge to the other side edge when the target sputters the first substrate and the second substrate. Furthermore, the formed curved surface electrochromic transparent device with high efficiency and uniform discoloration can be uniformly discolored.

Description

technical field [0001] The invention relates to a curved surface electrochromic transparent device, in particular to a curved surface electrochromic transparent device with high efficiency and uniform color change and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and the improvement of living standards, people have higher and higher requirements for the appearance and use experience of industrial products. For electrochromic devices with intelligent and fast color changing functions, changeable and soft curved surfaces that are more in line with public vision, and curved surface shapes such as aerodynamic streamline shapes that meet the requirements of products in the fields of locomotives, ships, aerospace and other fields, electrochromic devices are more and more popular in engineering. Attention of developers and users. [0003] The core component of curved surface electrochromic device is the combination...

AI Technical Summary

Problems solved by technology

[0005] Since the surface of the transparent substrate to be acted on is a special-shaped curved surface (including single and hyperboloid surfaces), the sputtering angle and sputtering distance will vary greatly during the sputtering process of the target material, resulting in uneven film thickness of the prepared film. And then affect the color uniformity of the electrochromic device

[0006] In addition, some large-area electrochromic devices also have the problems of excessive potential drop and insufficient driving force for color change, resulting in poor uniformity of color change and slow response speed.
