摘要

三基色LED背光存在两个独立的配色自由度

约束条件为夜视辐亮度不超标及与参考点之间色坐标偏差最小

在这两个约束条件下存在惟一最优的配色方案。文章通过二元线性回归方法

得到色坐标和辐亮度之间的近似依赖关系

并给出通过最少三次试配色获得的辐亮度测量结果推出最佳色坐标配置的计算方法。通过对多于三次测量数据残差的分析

表明在基本测量精度和样本点选取范围内

辐亮度估计的偏差可以控制在2%以内。

Abstract

There are two independent chromatic variables while matching the color of LED backlight based on three primary colors. Night vision radiant luminance and the departure from the color coordinates of certain reference point are two restrictions

under which there exists one and only best color matching scheme. By means of two variables linear regression analysis

approximate relations between radiance and color coordinates are given. Through trial and error procedure from least three rounds of radiant luminance measurement

the best configuration of color can be calculated. According to the analysis of mean residual

the error of estimated radiation can be less than 2% in basic accuracy of measurements and proper range of sampling points.
