A drive system is provided for driving an electrochromic display cell including an electrochromic material, a predetermined number of display electrodes, and a counter electrode confronting them, different combination of the display electrodes defining different desired display patterns. The drive system comprises a coloration circuit and a bleaching circuit driven at the same time. The coloration circuit is adapted for conducting coloration operations by applying a coloration voltage to selected ones of the display electrodes. The bleaching circuit is adapted for conducting bleaching operations by applying a bleaching voltage to the remaining display electrodes.
