Optical Design of Encapsulation for High EQE and Color Purity in OLEDs

Abstract

An optical encapsulation structure has been proposed to realize high external quantum efficiency (EQE) and color purity in flexible bottom-emission organic light-emitting diodes (OLEDs). It was designed based on the Fabry-Perot Interferometer (FPI) using optical simulation. The structure showed three sharp peaks in red, green and blue wavelength bands, respectively. © 2020 The Society for Information Display
