文章研究了微腔OLED的视角特性,结果表明,亮度和发光效率随着视角的增加逐渐减小,当视角增加到50°时,其亮度降为正面输出的1/3;发光效率下降了约40%左右;色坐标随着视角的增加产生漂移,而光谱峰值和半高宽基本不随视角的变化而变化。同时分析并讨论了视角特性产生的原因。

The angular dependence of QLED is studied and it showed that the brightness and current efficiency gradually decreased with increased view angle, the intensity and current efficiency at 50 degrees dropped to 1/3 and 40% respectively with respect to the normal direction. And Color coordinates produce drift at a certain extent with increased view angle, but spectral peak and FWHM didn＇t change depend on the angle. Reasons for the occurrence of angular dependence were discussed.
