High-Efficiency Organic Light-Emitting Diodes with a Complete Cascading Carrier Injection Structure

Abstract

In the present work, we study a comprehensive model to quantitatively investigate the position progression of electron transporting materials (ETMs) on exciton recombination probability and electric field distribution across the emissive and electron transport layer in dual-emissive layer organic light-emitting diode (OLED) devices via electrical simulation. The simulation outcomes show that the recombination profile across the emissive layers (EMLs) is highly influenced by the structural arrangement of ETMs. Moreover, experiment results also reflect similar behavior traits.
