The chromaticity coordinates have been measured with high precision by HRD-1 double monochromator using the developed software.

报导应用开发的软件功能，将HRD1双单色仪用于光源色的测量，该方法具有速度快、重复性好、精度高的优点。

The error analysis of the measuring results show that the spectral transmittance of LCD at different gray levels has obvious influence upon the chromaticity coordinates distribution.

测量结果的误差分析表明，LCD在小同灰度时的光谱透过率的变化对色坐标分布有较大影响。
