초록
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?밣erot (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 25혻×혻25 쨉m2 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.
