White-balance characteristic of quantum-dot backlight
摘要
Abstract
In order to realize color gamut extension and white balance of backlight source in liquid crystal displays,this paper researches light mixing theory of quantum-dot backlight in CIE1931 chromaticity system by using Gaussian curve fitting spectrum,and establishes spectral function model of quantum-dot backlight source,and further proposes a conversion method between quantum-dot spectrum and color coordinates.First,based on maintaining effective spectral information,the complex spectral data is fitted to conform to the superposition of Gaussian function.Then,color coordinate calculated by CIE1931XYZ system is used to solve spectral function and Gaussian parameters.Finally,the white balance of backlight source can be achieved.Experimental verification achieves the spectral power function and analyses the color characteristics of quantum-dot backlight with color temperature of 5 560 K,6 500 K and 10 000 K as a reference.Accurate and efficient mutual conversion between the spectrum and color coordinate can be achieved.These results simplify the form of spectral function and numerical computation,achieve the data compression,and provide a necessary technical basis and theoretical guidance for white-balance experiment of quantum-dot backlight source.关键词
