中文摘要:

      目的 在液晶显示器上小范围内精确地控制颜色的显示。方法 实验选择国际照明委员会推荐的5个基本颜色中心， 使用线性插值的方式在各颜色中心小范围内建立三维查找表， 实现小范围内精确控制液晶显示器颜色显示的目的。结果 该方法对 L*， a*， b*的控制精度分别为0.05， 0.08和0.03， 对色差的控制精度是0.18ΔEab个色差单位。结论 使用小范围内建立三维查找表的方式可以实现小范围内更精确显示颜色的目的， 为在液晶显示器上实现颜色视觉评价提供特性化基础。

英文摘要:

      The aim of this study was to precisely control the color display in a small range on liquid crystal displays. The experiment chose the five basic color centers from CIE as the experimental color centers and used a linear interpolation method to establish the 3-dimension look-up table in a small range around color centers to achieve precise control of color display. With this method, the control accuracy of L*, a*, b* was 0.05, 0.08 and 0.03 respectively, and was 0.18 for color difference of CIELAB. The establishment of 3-dimension look-up table around color centers in a small range can achieve more accurate display of color in a small range, providing a basis of characterization for the realization of color visual evaluation on the liquid crystal display.
