Working principle of the Zn-SVO electrochromic display

Caption

a, Schematic diagram of the bar-coating process. The inset shows a digital photograph of the SVO/cellulose paste. b, Schematic illustration of a Zn-SVO electrochromic display platform. c, Schematic illustration of the colour overlay effect via the combination of orange, yellow, and green colours. The upper colour code represents the colour of the top SVO electrode, while the lower colour code represents the colour of the bottom SVO electrode. d, Visible-near infrared transmittance spectra of the display under different colour states. e, Digital photograph of the display having an orange colour, showing an OCP of 1.56 V. f, Digital photographs of a 0.5 V regulated LED powered by the Zn-SVO electrochromic display at 1 min and 40 mins. g, Digital photographs of the Zn-SVO display showing six colours obtained through the colour overlay effect.
