Abstract

Abstract: Reversible electrodeposition (RED) devices have been considered as the optical transmittance or reflectance switchable display for the reflective display applications. In this study, transparent/colored mirror switchable RED device is demonstrated by integrating the Fabry–Perot (FP) interferometer. Indium‐tin‐oxide (ITO)‐based FP interference effect is utilized for color filter to emit particular wavelength. Color‐switchable RED cells are researched using ITO (red, green, and blue (RGB)) films and tungsten (W) films as partially reflective layers for the cavities. The red/green/blue colored mirrors are developed according to ITO thickness as the Ag film deposit. Then, the ITO (RGB) pixelated RED devices are investigated by differential deposition process. In the 25 × 25 µm 2 sized ITO (RGB) micro‐subpixels mirror, the high transparent and high reflectivity states are successfully achieved, which can be applied to reflective‐type transparent displays. Abstract : High‐resolution reflective‐type transparent/colored mirror switchable reversible electrodeposition device is demonstrated by integrating indium‐tin‐oxide‐based Fabry–Perot interferometer. The subpixel size of each of the red, green, and blue (RGB) colors is 25 × 25 µm 2, showing white reflection state and high transparent state. These results can be expected to utilize for high‐resolution transparent reflective display applications.
