A high‐dynamic‐range liquid crystal display (HDR‐LCD) can much enhance the contrast ratio of image and reduce power consumption upon the locally controlled dynamic backlight. Delta‐color adjustment(DCA) method with simple adjustment progress, was proposed and demonstrated on a 37″ HDR‐LCD to further reduce the power consumption, increase the contrast widen the NTSC ratio and can still maintain image details.
