Electrochromic device with shoulder-to-shoulder structure and application thereof

Abstract

The invention relates to an electrochromic device with a shoulder-to-shoulder structure. The electrochromic device comprises a common electrode unit, at least one color changing unit and an electrolyte layer, wherein the common electrode unit includes an electrode layer and an electrode protection layer arranged on the electrode layer, each color changing unit includes a transparent conductive layer and a color changing layer arranged on the transparent conductive layer, the common electrode unit and each color changing unit are arranged on the same plane, two adjacent units are provided withan insulating area therebetween, and the electrolyte layer covers the electrode protection layer in the common electrode unit and the color changing layer in each color changing unit and connects theelectrode protection layer in the common electrode unit and the color changing layer in each color changing unit. According to the invention, an electrochromic device with a sandwich structure is flattened into the electrochromic device with a shoulder-to-shoulder structure, thereby being conducive to realizing multi-color and personalized pattern design of the electrochromic device, and reducingthe difficulty of integration, softening and large-area design.

Description

technical field [0001] The invention relates to the field of electrochromic and electronic display, in particular to a side-by-side electrochromic device and its application. Background technique [0002] Electrochromic materials are smart materials that can undergo stable and reversible color changes under external electrical stimulation and have optical modulation capabilities. With the electrochromic material as the core layer, matching the corresponding electrolyte layer and the counter electrode layer can be assembled to obtain a sandwich-structured electrochromic device, which can be applied to assembly windows (also called smart windows), displays, file encryption and Color-changing glasses and other fields. [0003] The traditional electrochromic device is a sandwich structure similar to a battery integrated with a variety of materials, including a five-layer structure composed of a transparent conductive layer, an ion storage layer, an electrochromic layer and an e...

Problems solved by technology

[0004] However, in traditional electrochromic devices, the injection and extraction of cations are carried out in the vertical direction, and the ion storage layer and the color-changing layer are respectively located on different functional layers in the vertical direction, so the colors and positions of the two must match to be able to The color-changing layer can display its own color or color change, which limits the diversification and personalized design of electrochromic device colors to a large extent, and is not easy to integrate and flexibly design the device

In addition, the complex preparation process and high cost of traditional electrochromic devices have greatly affected the wide-scale commercial application of electrochromic devices.
