    • 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.
    • 提供了用于驱动电化学显示元件的方法。 还提供了采用该方法的装置。 该方法包括通过向电化学装置的像素施加黑化脉冲来沉积金属的黑化步骤,以及通过施加白化脉冲来溶解沉积的金属的增白步骤。 当电化学显示装置的显示被更新时,根据在更新之前的黑化步骤中金属沉积所经过的时间来调整施加持续时间和/或施加白化脉冲的电压 美白步骤 该方法使得电化学显示装置的像素的足够的白化,优异的耐久性和更新时间的缩短。
