A driving circuit for an electrochromic display cell wherein write and erase of a segment is effected by an alternating or pulse signal. A write or erase potential is applied across a segment and common electrode during a half cycle of the alternating/pulse signal which is predetermined to have a (activation) period less than that which is required to effect complete coloring or bleaching of the segment. Therefore, several cycles of the alternating/pulse signal are necessary to effect complete coloring or bleaching of the segment. |
