摘要

设计了结构为上反射镜/有机层/下反射镜/柔性基板的可弯曲式有机电致发光器件(FOLED)。利用几何光学模型计算了器件在不同弯曲情况下

其发光光谱随观测角和曲率的影响

并与平整器件的光谱作了比较。结果表明:1)基板向内弯曲时

随着观测角的增大

器件的发光光谱峰值出现蓝移

且蓝移的程度相对平整器件要大;随着曲率的增大

器件的发光光谱峰值出现蓝移。2)基板向外弯曲时

随着观测角的增大

器件的发光光谱峰值出现红移

但红移的程度不大;随着曲率的增大

器件的发光光谱峰值出现红移

且与基板向内弯曲时蓝移的程度相当。

Abstract

The fabrication of flexible organic light-emitting devices (FOLED) is an important development direction in the next generation of display technology. Based on the geometrical optics model

the optical characteristics of our FOLED with a structure of top reflecting mirror/organic material/bottom reflecting mirror/ flexible substrate were discussed. The influence of viewing angle and curvature on the performance of the EL spectrum was studied

the spectrum of FOLED and that of plane OLED were contrasted as well. It was found that:1) When substrate was incurvate

the peak value of the spectrum was blue shift as the viewing angle increasing

and the extent was broader than that of plane OLED. The peak value of the spectrum was blue shift as the curvature increasing; 2) When substrate was excurved

the peak value of the spectrum was red shift as the viewing angle increasing

but the extent was slight; the peak value of the spectrum was red shift as the curvature increasing

the extent was close approximately with that of plane OLED.
