OLED device having improved light output

Abstract

An organic light-emitting diode (OLED) device, comprising: a reflective element, a partially reflective semi-transparent electrode through which light from the OLED is emitted, and at least one layer of organic light-emitting material disposed between the reflective element and the partially reflective semi-transparent electrode; wherein either the reflective element comprises a reflective electrode or a transparent electrode is positioned between the reflective element and the organic light emitting material, and further comprising a light scattering element optically integrated into the OLED device for scattering light emitted by the light-emitting layer and reflected by the reflective element and the partially reflective semi-transparent electrode.
