ABSTRACT:
An electrochromic device which incorporates a reversibly color-changing organic polymer film as the display electrode. The display polymer film is capable of undergoing reversible oxidation and/or reduction to a charged, colored, conductive state. Upon reversing the charge, the polymer returns to its virgin color. The display films are comprised of linear fused heterocyclic ring systems, optionally with connecting units, or linear monocyclic ring systems and connecting units. The device requires low currents to operate and switch from the virgin state to the colored state. It also can optionally be operated to exhibit several colors.
