单层OLED器件模型的MATLAB分析计算

MATLAB Analysis and Computation of Single Layer OLED Device Model

近年来有机发光二极管(OLED)的工业应用特别是在平板显示器中的应用已被广泛研究。OLED发光是分别由阴极和阳极注入的电子和空穴在发光层中复合的结果。单层结构是OLED器件的基础。为了提高OLED器件的性能,需要详细理解电荷载流子的注入过程。借助MATLAB求解了无量纲单层OLED器件模型,介绍了有关分析计算方法和技巧。综合利用MATLAB提供的符号求解常微分方程、绘图等命令,可使工作量大为减少。该方法具有编程简单,使用方便、实用性强等特点。

Organic light-emitting diodes （OCED） have been extensively studied for industrial application, especially for flat panel displays in recent years. Light emitting in OLED is the result of the recombination of electron and hole in light emitting layer, which are injected from cathode and anode. Single layer structure is the basis of OLED device. To improve the efficiency of OLED device, a detailed understanding of the charge carrier injection processes is necessary. In this paper, the model of single layer OLED device in dimensionless form Was solved with the help of MATLAB, the analytical methods and skills were presented. The workload can be greatly reduced with synthesized use of a number of functions provided in MATLAB, such as symbolic solution of ordinary differential equations, plot etc. This technique is simple in programming, convenient in operation and practical.
