A method of driving an electrochemical display device comprises a working electrode (1,2) having a Prussian blue coating (4) thereon, a counter electrode (5,2) spaced from the working electrode and having a Prussian blue coating (4) thereon, and an electrolyte (8) in contact with the working electrode and the counter electrode, comprises applying a voltage that is greater than a predetemined voltage to the working electrode with respect to the counter electrode in order to cause colouration of the working electrode. A voltage which is less than the predetermined voltage is applied to the working electrode with respect to the counter electrode in order to cause bleaching of the working electrode. The predetermined voltage is between -0.6 volts and +0.2 volts. |
