Definitions

  • Electrochromic display units consist of at least fol ⁇ constricting three layers of an active electrochromic layer changes color due to oxidation or reduction, ei ⁇ ne electrolyte layer which transports ions for the oxidation or reduction, and an ion storage layer, which store the ions or release.
