摘要
三刺激值计算是求取各种色度量的基础。采用三刺激值的基本定义及其计算方法推导得到了色纯度为(0.33,0.33)的白光有机电致发光显示器(OLED)所需要的红、绿、蓝三基色的最佳亮度配比:红光为28.2%,绿光为57.1%,蓝光为14.7%,为实验前结构的选择提供了一定的理论基础。通过实验对其进行验证,得到色纯度为(0.25,0.32)的白光OLED,是由于器件中有机材料对各种波长的光有一定的吸收作用,使实验结果和理论有一定的差别,并对其进行分析。
The computation of tristimulus values is a basic step for obtaining various colorimetric quantities. Firstly, for white-OLED with CIE coordinates (0.33,0.33), the best brightness proportion of red 28.2%, green 57.1%, blue 14.7% is calculated by the definition of CIE tistimulus values and their numerical computation, which will provide a certain theory basic for the choice of the structure before the experiment. Secondly, the theory is tested thought the experiment. White-OLED with CIE coordinates (0.25,0.32) is prepared. Because of light absorption of organic material, the result of experiment and theory has the certain difference, and the reason is analyzed.
