Definitions

  • Light generated in the active element may be waveguided in various parts of the structure, including the electrodes, the organic layers, and/or the substrate (if it is transparent). This waveguided light may be absorbed within the structure of the active element or may be coupled out of the edges of the structure.
  • lateral does not limit the relative position of the topographical feature on the z-axis (i.e., the elevation or depression of the topographical feature relative to the active element).
  • the topographical feature can be positioned directly lateral to the active element.
  • the topographical feature can be positioned laterally at an elevation above the active element. Positioning of the topographical features laterally to the active element has the benefit of avoiding or reducing disruption to the emission of non- waveguided light.

Abstract

La présente invention concerne des diodes électroluminescentes organiques (OLED) possédant une efficacité de désaccouplement améliorée grâce à l'utilisation de caractéristiques topographiques qui diffusent la lumière. Lesdites OLED comprennent un substrat sur lequel est disposé un élément actif. Les caractéristiques topographiques sont situées dans une position telle qu'elles se trouvent dans le chemin de la lumière à longueur d'onde émise depuis l'élément actif. Dans certains modes de réalisation, les caractéristiques topographiques présentent des centres de diffusion qui diffusent la lumière à longueur d'onde émise depuis l'élément actif. Lesdits centres de diffusion peuvent être des microparticules. Dans certains modes de réalisation, les caractéristiques topographiques présentent une surface réflectrice qui réfléchit la lumière à longueur d'onde émise depuis l'élément actif. L'invention concerne également un procédé de fabrication d'une diode électroluminescente organique.
