Driving method for electrochromic display unit
专利汇可以提供Driving method for electrochromic display unit专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the deterioration in display quality caused by a coloring density difference among segments, by stabilizing the voltage of the opposite electrode during the write operation by performing the 1st erasing drive, write drive and 2nd erasing drive in sequence.
CONSTITUTION: The electrochromic display unit consists of display electrode 2 and opposite electrode 3 equipped with electrochromic substance layers 7 and 7' respectively. To drive this unit, only segments to be erased in the next display pattern are driven for the 1st constant-voltage erasing for tens m sec.Whundreds m sec. before write operation and then, only segment to be written in the next display pattern are driven for constant-voltage erasing for hundreds m sec. Further, only erasing segments in a new display pattern, i.e. erased segments are driven again for the constant-voltage erasing
