The erase time of a heptyl-viologen dihydrogenphosphate electrochromic display system is extremely temperature sensitive. A major contributory factor has been found to be the deposit resistance variation with temperature. In a practical display, the erase speed at room temperature and below is too high and biasing of the display at a temperature of 35-40 degrees C has been found to be necessary.
