Abstract

A driver circuit for an electrochromic display device which includes segment electrodes and a common electrode. The driver circuit has a power source, switching means connected between the power source and the segment electrodes, and circuit means disposed between the common electrode and the power source. The circuit means is operative to couple the common electrode to either a positive terminal or a negative terminal of the power source, whereby an electric current will flow through the segment electrodes in bleaching and coloring directions with the use of a single power source.
