Electrochromic display device
First Claim
1. Electrochromic display apparatus, comprising:
- an electrolyte containing an electrochromic material,a plurality of display electrodes in said electrolyte,said display electrodes being electrically connected in at least one group to enable selection of display electrodes,means for selecting at least some display electrodes,means to effect deposition of a visible coating of coloured species derived from the electrochromic material onto said selected display electrodes, andmeans to effect deposition of an invisible coating of the coloured species onto all unselected display electrodes,whereby the potentials of selected and unselected display electrodes are equalised.
