A method is provided for driving an electrochemical display element. An apparatus employing the method is also provided. The method comprises a blackening step for depositing a metal by applying a blackening pulse to a pixel of the electrochemical device, and a whitening step for dissolving the deposited metal by application of a whitening pulse. When the display at the electrochemical display device is being updated, the duration time of application and/or voltage of application of the whitening pulse is adjusted in accordance with the time elapsed since the deposition of the metal in the blackening step before the update in the whitening step. This method enables sufficient whitening of the pixel of the electrochemical display device, excellent durability, and shortening of the time for update.
