摘要： An electrochromic display device having first and second electrodes, and a plurality of display electrodes, all immersed in a liquid electrolyte. Drive means act to first generate a potential difference between said first and second electrodes to cause a color species to be deposited on said first electrode and, thereafter, act to generate a potential difference between said first electrode and selected ones of said plurality of display electrodes to cause the color species to be transferred to the selected ones of said plurality of display electrodes. Heptyl viologen dibromide is suggested as one possible electrolyte.
