Definitions

  • the present invention relates to a tandem organic light emitting device, and more particularly, an electron layer doped with a metal dopant and an electron layer doped with an organic dopant are sequentially stacked on one side of the charge generation layer, thereby driving voltage in the charge generation layer driving region.
  • the present invention relates to a tandem organic light emitting device having improved power efficiency and lifespan.
  • the conventional charge generating layer has a high driving voltage, which has a problem of lowering power efficiency and lifespan of the organic light emitting device.
  • the hole layer may have a multilayer structure, and a first hole layer and a second hole layer may be sequentially formed based on the emission layer.
  • the first electrode 200, the second electrode 300, the organic light emitting layer 400 of the internal space partitioned by the base substrate 100 and the rear substrate (not shown) and the sealing material formed on the edge facing each other And internal spaces other than the space occupied by the charge generation layer 500 may be filled with an inert gas or formed in a vacuum atmosphere.
  • the electron layer 430 includes the second electron layer 432 and the third electron layer 433, electrons are injected from the second electrode 300. (Not shown), the second electronic layer 432 and the third electronic layer 433 is moved to the light emitting layer 410.

Abstract

La présente invention concerne un élément électroluminescent organique en tandem, plus particulièrement un élément électroluminescent organique en tandem qui peut diminuer une tension d'excitation dans une région d'excitation d'une couche de génération de charge en stratifiant séquentiellement une couche d'électronique, qui est dopée avec un dopant métallique, et une couche électronique, qui est dopée avec un dopant organique, sur un côté de la couche de génération de charge, présentant ainsi un rendement de puissance et une vie utile augmentés. À cet effet, la présente invention concerne un élément électroluminescent organique en tandem qui est caractérisé en de qu'il comprend : un substrat de base ; une première électrode formée sur le substrat de base ; une seconde électrode formée en face de la première électrode ; deux, ou plus, couches électroluminescentes organiques, formées entre la première électrode et la seconde électrode, qui comprennent une couche électroluminescente, une couche de transfert de trous formée entre la couche électroluminescente et la première électrode, et une couche électronique formée entre la couche électroluminescente et la seconde électrode ; et une couche de génération de charge formée entre les couches électroluminescentes organiques voisines, la couche électronique formée entre la couche électroluminescente et la couche de génération de charge présentant une structure multicouche, tout en comprenant une première couche électronique dopée avec un dopant métallique et une seconde couche électronique dopée avec un dopant organique.
