摘要
白光有机发光二极管可以作为照明、全彩色显示器的光源,成为显示领域研发的重点方向。但白光有机发光二极管的实现还存在性能控制较难,色坐标易漂移等问题。本文通过有机发光二极管器件白光实现及其色坐标计算,初步获得实现白光OLED器件红、绿、蓝三基色的优化比,通过实验验证制备了色坐标为(0.31,0.35)的白光OLED器件,进一步通过理论计算和实验优化,减少红光掺杂浓度和增加绿光掺杂比例,实现接近标准白光(0.33,0.33)的有机发光二极管器件制备。
White-light OLED devices can be used as a surface light source and for full color displays,which have become the focus of OLED research and development.However,there are some shortcomings in the realization of white-light OLED devices,such as insufficient luminous performance,difficult process control,and easy color drift.To solve these problems,the optimized ratios of primary colors(red,green,and blue)of organic OLED devices were preliminarily obtained through the realization of white light and calculation of the color coordinate.An experimental white-light OLED device was prepared with a color coordinate of(0.31,0.35).Further,theoretical calculations and experimental optimizations were carried out to reduce the red-light doping concentration and increase the green-light doping ratio to realize standard white-light(0.33,0.33)OLED devices.
