Segment Color Control (SCC) 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 by using locally controlled dynamic backlight. A novel method, segment color control (SCC) method, was proposed with low, complexity, and had been demonstrated on a 37" HDR-LCD. By using the segment color control method, the contrast ratio of image on a 37" HDR-LCD TV was successfully improved to similar to 40,000:1 with clear image detail, and about 10%similar to 50% power saving. Furthermore, the SCC method further widened the color gamut from 108%NTSC to 125%NTSC.
