| 摘 要： | 显示器的色域决定了显示器能够显示的颜色范围,且色域覆盖率也是显示器测试的一个重要参数。由于颜色三属性中包含亮度,所以对显示器进行色彩和色域测试时应该考虑亮度因素Y,这就需要在三维的色空间下进行分析。文中分析了LCD显示器背光源亮度对色域覆盖率和色饱和度的影响,以及色饱和度对色域覆盖率的影响。用MATLAB绘制出在不同的...

| Abstract: | The color gamut determines the range of colors that the monitor displays,and the color gamut cov erage rate is an important parameter in the quality evaluation of LCD monitor.As brightness is one of the three at tributes of color,it should be considered when the color and color gamut are analyzed in 3D color space.The ef fect of the brightness of LCD backlight on color gamut coverage and color saturation is analyzed,and the effect of the color saturation on the color gamut coverage is also analyzed.3D color gamut coverage is obtained by the different formulas in the different color spaces using MATLAB.The effect of the brightness on the color gamut area and chroma is analyzed and compared.The results show that CIEDE2000 formula is most suitable to evalu ate the color of monitor among CIEDE2000 formula,CIEL*a*b*formula and CIEL*u*v*formula. |
