The application provides an electronic device, a camera module, an electrochromic element and a preparation method thereof; wherein, the electrochromic element comprises a first substrate and a second substrate arranged oppositely, the first substrate and the first substrate A plurality of conductive layers are sandwiched between the two substrates, and the conductive layers on the same side of the substrate are partially stacked to form a plurality of connected discoloration areas between the first substrate and the second substrate, and the discoloration The area is filled with color-changing material. The electrochromic element forms a structure of a plurality of conductive layers in a way of stacking cakes, that is, the conductive layer structures are stacked in the Z direction (thickness direction), and the adjacent conductive layers are separated by an insulating layer; this conductive layer The stacking method of the layers can make no gaps between adjacent color-changing areas, avoid black circles (or non-color-changing areas) between adjacent color-changing areas, have clear and accurate color-changing boundaries, and have a large amount of effective light, which is beneficial to the structure. characteristics of miniaturization. |
