Abstract: Each display electrode (1,2) is connected to a respective switch through a conductive path (3,4,5). The display electrodes are divided into a number of subsets each of which is formed in respective layers so that the electrodes of an upper subset overlap the edges (10) of the electrodes of the lower subset. The layers are separated by intermediate layers of electrically insulating material (11). The conductive paths from each higher subset pass through gaps between electrodes of any lower subset and through the insulating layers to connect their respective electrodes to the corresp. switches.

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: A chromium electroplating electrolyte comprising a source of trivalent chromium ions, a complexant, a buffer agent and a sulphur species selected from sulphites and dithionites, the complexant being selected so that the stability constant K1 of the chromium complex as defined herein is in the range 10 M preferably the chromium ions have a molar concentration lower than 0.01M. Complexants within this range include aspartic acid, iminodiacetic acid, nitrilotriacetic acid, 5-sulphosalicylic acid and citric acid.
