Abstract

The performance of optical light-coupling of Top-emitting organic light-emitting diode (OLED) is mainly suppressed by surface plasmon polaritons (SPP) on the interface between metal and organic layer, and micro-cavity effect between two metal electrodes. To reduce their influence and enhance the light extraction efficiency, an electromagnetic model of top-emitting organic light-emitting diode (TEOLED) with metallic grating anode is proposed in this report. The numerical simulation is implemented to research the performance of metallic grating anode that can enhances the light extraction efficiency of OLED by recovering the energy of surface plasmon polariton mode between organic-metal interface. The simulation based on the Finite Element method (FEM) and Finite difference time domain (FDTD) shows the field distribution and transmission spectrum of proposed TEOLED model, and then indicates the ability of metallic grating anode to improve the light extraction efficiency significantly, which provides a new approach to enhance the efficiency of top-emitting OLED.
