Abstract
A driving technique is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display electrodes, different combinations of the display electrodes defining different desired display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display electrodes. In transition of a visual display from a specific display pattern to another, voltages are applied to only the one or more display electrodes which are not common to the two display patterns, while no voltages are applied to the one or more display electrodes common to the two display patterns. Applications of a coloration voltage to particular one or more display electrodes and a bleaching voltage to different one or more display electrodes in transition of a visual display are initiated at a same time to reduce the time period required to transcend from one visual display to another.
