1. A full-color reversible switching device controlled by electrochemistry, comprising a color-changing layer and an electrolyte;
wherein the color-changing layer comprises a substrate, a conductive layer and an active material layer, and the active material layer and the conductive layer or the substrate layer forms optical interference to produce a structural color;
the electrolyte is connected to the conductive layer or the active material layer, and_in response to an electrochemical reaction occurring between the electrolyte and a surface of the conductive layer or the active material layer, a thickness of the active material layer changes such that the change in the thickness of the active material layer directly effects a color change of said structural color.
