A color-reflective LCD with high optical performances and cost-effective structure has been proposed by cholesteric liquid crystal technology. By way of color dithering algorithm and waveform module (WF) in SOC, we demonstrated a 13.3-inch Ch-LCD with a high resolution of 202 PPI, high reflectance of 30%, and high color gamut of 20%, which is suitable for electronic signage applications.
