用于调色系统的白光OLED厚度的设计

Design of white-OLED thickness based on mixing colors system

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.
