Doubling The Light Outcoupiing Efficiency Of Quantum Dot Light Emitting Diodes

Abstract

We utilize the dipole model to analyze the light outcoupiing and angular radiation pattern of the quantum dot light emitting diodes (QLEDs). Red, green and blue QLEDs are used as examples and the simulation results match well with the experiment We then confirm that by combining a high refractive index glass substrate with macroextractors, the light outcoupiing efficiency can be doubled. And electroluminescent spectra analysis at different angle demonstrates that all three QLEDs have small color shift.
