"more sustainable, efficient, bistability (up to 24 hours without power), low power consumption (0.7 μW/cm2 for static content), full-color capabilities, less eye strain... natural light transmission/ reflection rather than light emission... both conductor/ ion-storage, enabling flexible, all-polymer electrochromic fabrication with 1 layer transparency, conductivity, ion-storage... better withstands humidity/ temperature/ long-term electrochemical cycling... solution processing... scalable photolithography"
