Photographs and schematic of (a) transparent state and (b) colored state of ECD. c Photographs of the colored state with applied voltage of −2.0 V, −1.5 V, −1.0 V and transparent state (2.0 V) of ECD. d Optical transmittance spectra of the transparent (2.0 V) and colored states with external voltages of −1.0 V, −1.5 V, and −2.0 V. e Absorption spectra of the transparent and colored states of ECD. f Variation in the optical density relative to charge density measured at 550 nm. g Normalized transmittance during the pulse potential cycling. ECD electrochromic display.
