Abstract
An electrochromic display device, e.g. in an electronic timepiece, comprises a driver (19) for transferring coloration electric charge from a first display electrode group to a second display electrode group by applying a voltage therebetween. During the memory period between display changes, transfer signal generator (18) controlled by a transfer control signal generator (17) applies an auxiliary positive signal to the bleached electrodes and a negative signal to the coloured electrodes, whereby degradation of the display (20) during a memory period is prevented. Some of the electrodes may be dummies, screened from view, to allow the total coloured area to remain constant. <IMAGE>
