Delta-color adjustment (DCA) method for color controlled backlight of high dynamic range LCD-TVs

Abstract

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 back-light. 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.
