ABSTRACT:
An electrochromic display device includes a cermet electrochromic film. The cermet may comprise a conventional electrochromic material, such as tungsten oxide, and a noble metal, such as gold. In a preferred embodiment, the electrochromic cermet material includes a metal content of about 25 atomic percent. The electrochromic cermet is blue as prepared, and, when colored, is red. This electrochromic cermet material can be used in combination with other electrochromic materials, such as tungsten oxide, so as to result in a multicolor electrochromic display.
