Optical and Thermal Analysis for Polymer Light-emitting Diode as A Flat Panel Light Source
摘要
Abstract
The light out-coupling efficiency of polymer light-emitting devices (PLED) flat panel based on poly [2-me-thoxy-5-(2-ethyl-hexyloxy )-l, 4-phenylenevinylene] (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 panel' s 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.关键词
