Abstract

In this work modelling of two dimensional of a fluorescence based Organic Light Emitting Diode (OLED) using plastic as flexible substrate is presented. The Finite Difference Time Domain (FDTD) mathematical modelling has been used to analyse the light extraction efficiency from fluorescence based Organic Light Emitting Diode (OLED). The OLED structure has been simulated by using 2D Hexagonal photonic crystal lattice. The Finite Difference Time Domain (FDTD) method is used to model and simulate the OLED structure. An enhancement of Internal Quantum Efficiency (IQE) and Light Extraction Efficiency (LEE) has been achieved by inserting Photonic Crystal above the emissive layer. The improvement in the extraction efficiency of OLED structure is achieved by increasing the radiative decay rate and by optimizing the angular distribution of light through the substrate.
