摘要
An electrochromic display device comprises an electrolyte contained between a pair of spaced-apart substrates. A set of electrodes are disposed on at least one of the substrates in contact with the electrolyte and a layer of electrochromic material is disposed on at least one of the electrodes to define a display electrode. The electrochromic material comprises a color-reversible salt of iron(III) hexacyanoferrate(II) which, depending on its oxidation-reduction state, exhibits different colors. A source of electric charge is connected through circuitry to effect reversible electrochemical oxidation and reduction of the salt of iron(III) hexacyanoferrate(II) to effect a corresponding reversible color change exhibited by the display electrode.
