多元色液晶电视显示器色重显特性

Color Reproduction Characteristic of Multi-primary-color LCD TV Display

为研究多元色液晶显示器的色重显特性,采用特定色块测量的方法,以实测色度参数构建多元色液晶显示器的重显色域,分别在二维、三维色空间分析其色域特性,并与其他重要标准色域做了比较。结果表明,多元色液晶显示器的三维色域范围大于宽目标色域Pointer色域,特别是在高明度区更加明显。色度测量结果还显示,额外增加的黄元色的色饱和度并不高,也未使色域覆盖率得到显著提高,但高亮度黄元色使多元色液晶显示器的光效率得到很大提高。

In order to research the color reproduction characteristic of multi-primary-color LCD display, a set of specific color blocks are adopted in the experiments to construct the reproduction color gamut of multi-primary-color LCD display based on the measured value of color parameters. The characteristics of color gamut in 2D and 3D color space are analyzed respectively, and other important standard color gamuts are compared. The results show that the 3D color gamut of multi-primary-color LCD display is larger than the targeted wide color gamut, Pointer color gamut, especially in the high luminance area. It is also shown by the chromatic measure results that the saturation of the additional primary, Yellow, is not high and doesn＇t significantly improve the coverage ratio of color gamut either, but it does significantly improve the optical efficiency of multi-primary-color LCD display.
