We propose a color realization method of a reflective display based on quick response-liquid powder display (QR-LPD). We use the particle-moving method in order to address the color particles cyan, magenta, yellow, and black (CMYK) into their respective cells. We fabricated a color addressed reflective display panel using indium-tin-oxide (ITO) glass with a rib width of 15 μ m, a cell size of 300 μ m× 300 μ m, an average particle diameter of 8 μm, and a particle charge to mass ratio (q/m) from +8.5 μC/g to -4 μC/g. Most particles are inserted into their cells on the upper substrate, with non-movable particles removed in a previous step. The fabricated color panel shows a well-addressed CMYK array in microscopic photographs. An additional color display is fabricated using line-by-line addressing in order to facilitate the addressing process.
