Title
(EN) LIGHT-EMITTING DEVICE AND METHOD OF MANUFACTURING A LIGHT-EMITTING DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT ET SON PROCÉDÉ DE FABRICATION DE CELUI-CI
Abstract
(EN)
The invention describes a method of manufacturing a light-emitting device (1), which light emitting device (1) comprises a first electrode layer (2) and a second electrode layer (15) and a light-emitting layer stack (13, 14) arranged between the first electrode layer (2) and the second electrode layer (15), which method comprises modifying an electrical property of the electrode material within a specific region (R1, R2) of the first electrode layer (2) such that an injection of charge carriers into the light- emitting layer stack (13) is inhibited over the modified region (R1, R2) of the first electrode layer (2) to give a corresponding dark region (D1, D2) in an outcoupling surface (16) of the light emitting device (1). The invention further describes a light- emitting device (1) comprising a first electrode layer (2) and a second electrode layer (15) and a light-emitting layer stack (13, 14) arranged between the first electrode layer (2) and the second electrode layer (15), and wherein the first electrode layer (2) comprises a specific region (R1, R2) in which an electrical property of the electrode material has been modified such that an injection of charge carriers into the light-emitting layer stack (13) is inhibited in that modified region (R1, R2) to give a corresponding dark region (D1, D2) in an outcoupling surface (16) of the light emitting device (1)

La présente invention concerne un procédé de fabrication d'un dispositif électroluminescent (1), qui comprend une première (2) et une seconde (15) couche d'électrode ainsi qu'une pile de couches électroluminescentes (13, 14) placée entre la première (2) et la seconde (15) couche d'électrode. Ledit procédé comprend la modification d'une propriété électrique du matériau d'électrode dans une région spécifique (R1, R2) de la première couche d'électrode (2) de sorte qu'une injection de vecteurs de charge dans la pile de couches électroluminescentes (13) soit évitée sur la région modifiée (R1, R2) de la première couche d'électrode (2) pour donner une région sombre correspondante (D1, D2) sur une surface de couplage sortant (16) du dispositif électroluminescent (1). L'invention concerne également un dispositif électroluminescent (1), qui comprend une première (2) et une seconde (15) couche d'électrode ainsi qu'une pile de couches électroluminescentes (13, 14) placée entre la première (2) et la seconde (15) couche d'électrode, la première couche d'électrode (2) comprenant une région spécifique (R1, R2) dans laquelle une propriété électrique du matériau d'électrode a été modifiée de sorte qu'une injection de vecteurs de charge dans la pile de couches électroluminescentes (13) soit évitée dans cette région modifiée (R1, R2) pour donner une région sombre correspondante (D1, D2) sur une surface de couplage sortant (16) du dispositif électroluminescent (1).
