Electronic timepiece with electrochromic display element

摘要

An electronic timepiece with a digital display device employing electrochromic materials, such as titanate and niobate, as an electro-optical element. An electrochromic material produces different states of coloration depending upon the polarity of voltage applied thereto for a remarkably long period, and with a minimum of power consumption, whereby the timepiece enjoys a minimization in its size, a long life for its battery, and a variable design in the display.
