摘要：
A combined constant potential and constant voltage driving technique is utilized which is much more effective to drive an electrochromic display. The electrochromic display manifests the electrochromic phenomenon to place the display in a colored state or a bleached state in response to current applied thereto. A constant potential driving manner is employed in coloring the electrochromic display, while a constant voltage driving manner is employed in bleaching the same.
