Abstract

The invention provides an electrochromic device and electronic equipment. The electrochromic device comprises a first substrate layer, a first conductive layer, an electrochromic layer, a second conductive layer and a second substrate layer which are stacked in sequence, and the surface resistance of the first conductive layer is greater than that of the second conductive layer. According to the electrochromic device disclosed by the invention, through matching of the first conductive layer with relatively high surface resistance and the second conductive layer with relatively low surface resistance, the effects of clearly displaying the color of the electrochromic layer and rapidly and uniformly changing the color of the electrochromic device are synergistically realized.

Description

technical field [0001] The invention belongs to the technical field of electrochromism, and relates to an electrochromic device and electronic equipment. Background technique [0002] Electrochromic devices have a wide range of applications in automotive, architectural, and consumer electronics. [0003] The electrochromic device is generally composed of a laminated first substrate layer, a first conductive layer, an electrochromic layer, a second conductive layer and a second substrate layer. Under the action of an external electric field, the material of the electrochromic layer undergoes a reversible redox reaction, and the optical properties of the electrochromic device exhibit a stable and reversible change in color or transmittance. In some application scenarios, such as shell decoration, users tend to see bright colors. Taking the side of the first base layer facing the user's eyes as an example, the ambient light passes through the electrochromic device and is refl...
