An ultrafast electrochromic display is fabricated based upon well defined nanotube arrays of poly(3,4‐ethylenedioxythiophene), PEDOT (see Figure). The thin nature of the nanotube walls (10 – 20 nm) offers a short ion‐diffusion distance, which results in an ultrafast switching rate (color‐switching time < 10 ms). The arrayed long nanotube structure furnishes strong coloration.
