Abstract
AbstractReversible 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 µm2 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.
