ABSTRACT:
A drive system is provided for an electrochromic display which includes an electrochromic material, a display pattern electrode and a counter electrode. The electrochromic phenomenon, or, reversible variations in the light absorption properties are developed when a predetermined voltage is applied between the display pattern electrode and the counter electrode. An erase pulse is applied to a bleached state display pattern electrode when a certain display pattern is held for a period longer than a memory period of the electrochromic display in order to regenerate the memory state and enhance the visibility.
