The green-based 180 Hz Stencil-FSC method was proposed to effectively suppress color breakup for a field-sequential-color liquid crystal display (FSC-LCD). Nevertheless, this method has an issue on green color desaturation. Therefore, we further propose the “limited backlight signal ratio” (LBSR) to determine a proper backlight signal to increase image color saturation and simultaneously suppress color breakup. To realize a thin and high image quality eco-display, in addition, the light spread function model and the number of backlight divisions for a side-lit backlight are optimized and combined with the LBSR stencil-FSC method.
