摘要: A high-dynamic-range liquid crystal display (HDR-LCD) which studies as a dual-panel display can much enhance the contrast ratio of image and reduce the power consumption upon the locally controlled dynamic backlight. A simple modulated algorithm, Delta-Color Adjustment (DCA) method, was proposed to determine the RGB-LEDs backlight modulation for high image quality. By implementing the DCA method on a 37 '' HDR-LCD TV with 8 x 8 backlight zones, the contrast ratio of a high contrast image can reach similar to 40000:1 with clear image detail and 40% power reduction. Furthermore, by controlling the R, G, and B LEDs individually, the color gamut can be enlarged to 125% NTSC.
