Abstract
LEDs have uniform problems include brightness aspect and color aspect,which would reduce the image quality of LED displays.This paper gives a method to correct the color gamut of LED displays.The method can solve the uniform problems,while correct the color gamut of LED displays accurately.This paper establishes a linear mathematical model of LED displays'colors,analyzing the target color gamut of LED displays.Then,the correction method with the target color gamut as LED displays'color gamut is introduced.Furthermore,white balance in color gamut correction method is introduced to fix the color coordinates of colors accurately.Experimental results showed that this method can correct the color gamut of LED displays into target color gamut accurately.
