Abstract: A chromium electroplating electrolyte containing trivalent chromium ions, a complexant, a buffer agent and thiocyanate ions for promoting chromium deposition, the thiocyanate having a molar concentration lower than that of the chromium ions. The chromium preferably has a concentration lower than 0.01M. Preferably the complexant is selected so that the stability constant K1 of chromium complex is in the range 10 M . Complexants in this range include aspartic acid, iminodiacetic acid, nitrilotriacetic acid and 5-sulphosalicylic acid.

Abstract: An electrochromic display, preferably employing an organic electrochromic material such as heptyl viologen, has display electrodes with a rough surface in contact with the electrochromic material, and is operated at a current density such that the diffusion depth of the material conforms to the contours of the electrodes.
