Abstract
The embodiments of the present invention discloses an electrochromic grating, a display panel and a display device. The electrochromic grating comprises: a cathode, a first electrochromic layer, an ion transport layer, a second electrochromic layer and an anode arranged in a stack: Under an effect of a same electric field, materials of the first electrochromic layer and the second electrochromic layer have contrary light transmission properties in an oxidation state: and the materials of the first electrochromic layer and the second electrochromic layer have contrary light transmission properties in a reduction state That is the material of the first electrochromic layer in the oxidation state is a dark state, and the material of the second electrochromic layer in the reduction state is a dark state. Or the material of the first electrochromic layer in the reduction state is a dark state, and the material of the second electrochromic layer in the oxidation state is a dark state. Since the first electrochromic layer and the second electrochromic layer can be in dark state simultaneously when the materials of the first electrochromic layer and the second electrochromic layer are in t…
