摘要
介绍了求解OLED器件黑点扩散模型的一种半解析/半数值计算方法。该方法综合利用Matlab提供的求解常微分方程、矩阵行列式、数值积分等函数,可使模型分析计算的工作量大为减少。给出了杂质浓度的计算公式,对于其中涉及的积分方程,基于数值逼近原理,采用多项式拟合函数近似求解。该方法具有编程简单、使用方便、实用性强等特点。
A semi-analytical/semi-numerical method was presented for solving dark spot diffusion model of organic light emitting diode（OLED）.The workload of model analysis and computation was greatly reduced by utilizing a number of functions in Matlab,such as symbolic solution of ordinary differential equations,matrix determinant,numerical integration and etc.Formulas for calculating impurity concentration were presented,where the related integration equation was solved with polynomial fitting function based on the principle of numerical approximation.This technique is simple in programming,convenient in operation,and practical in universality.
