The electrochromic displays (ECDs) are able to modulate their optical transmittance by applied voltage. Their energy saving features such as low-power consumption, and excellent optical memory effect enable them to provide as smart windows. Recently, we have investigated poly(3,4-propylenedioxythiophene) derivatives (PRs) to achieve high color contrast and bistability. Further, precise control on the potential at electrodes afforded high stability, and low-power consumption. Through the relationship on the thickness and the potential at each electrode, we could design a charge transfer mechanism. This mechanism was applied on the electrochemical capacitors along with high energy density and power density. The energy stored in ECDs could be transferred to the other electronics. In this process, the remaining energy in the ECDs could be confirmed by their color. For the future, this strategy presents a new path to achieve various electrochemical devices for multiple functions. |
