摘　　要：选择7种色温,分别测试了四元色液晶显示器的色度参数,并基于测试数据,分析了色温与液晶显示器亮度、彩度、色调和色域覆盖率的关系。结果表明,色温升高时,液晶显示器的亮度加大,色域覆盖率减小,还引起某些颜色色调和彩度失真。Based on the data of the test by choosing seven color temperatures and testing the colorimetric parameters of the four primary colors liquid crystal display, the relations of the color temperature and the brightness, ehroma, tone, color gamut coverage of the liquid crystal display are analyzed. The result shows that while the color temperature rises up, the brightness of the LCD increases, and the color gamut coverage decreases with the distortion of some color tones and chromas.

关 键 词：液晶显示器 色温 色调 彩度 色域覆盖率
