Abstract
An electrochromic device is disclosed, including two electrochromic elements, which are switched in a time separated manner. Each electrochromic element is arranged of electrochemically active material, and connected to a counter layer by a solidified electrolyte. In at least one embodiment, the electrochromic device further includes at least one resistive device which restricts the electrochemical reaction of one of the electrochromic element, such that a color of this electrochromic element is not substantially altered until the other electrochromic element is reacted to a predetermined extent.
