Flexible electrochromic film for glasses

Technical Field

Background

At present, in recent years, with the deep research on electrochromic and the development of related application scenes, electrochromic series products gradually attract people's interest and begin to be industrialized preliminarily. In addition to the first proposed intelligent color-changing windows for buildings and anti-glare rearview mirrors for automobiles, the concept of intelligent color-changing glasses is also newly proposed in recent years. The traditional electrochromic products (such as a color-changing window and an automobile rearview mirror) mostly use conductive glass as a substrate, and liquid-phase color-changing materials are arranged in the middle. In contrast, the AR color-changing glasses are characterized by smaller area, which also puts higher requirements on color-changing uniformity and color-changing speed; chinese patent No. CN210894854U discloses a lens for AR glasses, in which the use of a first transparent substrate and a second transparent substrate cannot be adapted to the curvature requirements of different types of glasses.
