摘要

运用传输矩阵法及MATLAB软件模拟计算了以MEH-PPV为发光材料的PLED面光源出光率

分析了发光层、PEDOT层、ITO层对器件出光率的影响。模拟分析了玻璃表面半球形、圆台形、圆锥形3种微形貌对器件出光率的影响。仿真结果表明

玻璃表面为圆锥形微散射层对提高器件出光率最有利

且出光均匀性最好。最后分析了PLED面光源工作状态下的热特性

发现发光层的热量容易积聚不易导出。该研究为大面积有机发光照明的优化设计提供了理论依据。

Abstract

The light out-coupling efficiency of polymer light-emitting devices (PLED) flat panel based on poly (MEH-PPV) was simulated by applying the transfer matrix method and software MATLAB. The influence of emitting layer

PEDOT layer

ITO layer on the performance of the PLED flat panels out-coupling efficiency was studied. The influence of different micro shapes on glass surface

such as flat panel

hemispherical shape

circular mesa

and conical shape

is simulated by software TRACEPRO. The results show that the light out-coupling efficiency is the largest and the uniformity of flat panel light output is the best when the glass surface is with micro conical shape. At last

the thermal properties were studied during the working of PLED flat panel. A great quantity of heat in emitting layer can not be diffused quickly. These results provided a basis for the optical and thermal optimization of PLED flat panel light source.
