ABSTRACT:
A driving circuit for an electrochromic display cell wherein writing and erasing of electrode-segments are effected by relatively high write and erase transition potentials. After a predetermined transition period, the written and erased electrode-segments are stabilized at a desired coloration or transparency, respectively, by application of a maintaining write potential and a maintaining erase potential. The maintaining potentials are at a lower level than the respective transition potentials. In this manner, the write and erase charges or potentials on the electrode-segments are substantially maintained at a desired level to maintain the desired contrast ratio between the written and erased electrode-segment.
