Title:
POLYCHROME ELECTROCHROMIC STRUCTURE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/172901
Kind Code:
A1
Abstract:
Disclosed is a polychrome electrochromic structure, comprising a working electrode, an electrolyte and a counter electrode, wherein the electrolyte is distributed between the working electrode and the counter electrode; the working electrode comprises an electrochromic layer; the electrochromic layer comprises a first reflection face and a second reflection face arranged opposite each other and in parallel; a dielectric layer is provided between the first reflection face and the second reflection face; the first reflection face, the second reflection face and the dielectric layer form an optical cavity; and the dielectric layer is mainly made of an electrochromic material. The polychrome electrochromic structure can realize the fusion of structural colors and electrochromism, thereby presenting a rich and colorful change in color, and is simple in structure, can be easily prepared, has a low cost, and has a wide application prospect. In addition, also provided are a preparation method and an adjustment and control method for the polychrome electrochromic structure, an electrochromic device and an image display device comprising the polychrome electrochromic structure, etc.
