Title (EN) OLED DEVICE HAVING SPACERS
(FR) DISPOSITIF A DIODE ELECTROLUMINESCENTE ORGANIQUE COMPRENANT DES ELEMENTS D'ESPACEMENT
Abstract:
(EN) An organic light-emitting diode (OLED) device, comprising: a substrate; an OLED formed on the substrate comprising a first electrode, one or more layers of organic material, one of which emits light, and a transparent second electrode formed over the one or more layers of organic material, the transparent second electrode and layer(s) of organic light-emitting material having a first refractive index range; a transparent cover having a second refractive index; a light scattering layer located between the substrate and cover for scattering light emitted by the light-emitting layer; and an auxiliary electrode grid located above the transparent second electrode, providing spacing between the transparent second electrode and the cover, and forming transparent gaps between the transparent second electrode and the cover within grid openings, the transparent gaps having a third refractive index lower than each of the first refractive index range and second refractive index.
(FR) L'invention concerne un dispositif à diode électroluminescente organique (DELO) comprenant : un substrat ; une DELO formée sur le substrat, comportant une première électrode, une ou plusieurs couches de matière organique, dont une qui émet de la lumière, ainsi qu'une seconde électrode, transparente, formée sur une ou plusieurs couches de matière organique, la seconde électrode et la ou les couches de matière électroluminescente organique possédant une première plage d'indice de réfraction ; une couche de revêtement transparente possédant un deuxième indice de réfraction ; une couche de diffusion de la lumière située entre le substrat et la couche de revêtement, conçue pour diffuser la lumière émise par la couche électroluminescente ; et une grille d'électrode auxiliaire disposée au-dessus de la seconde électrode, permettant de former un espace entre la seconde électrode et la couche de revêtement, et formant des espaces transparents entre la seconde électrode et la couche de revêtement au niveau des ouvertures de la grille, les espaces transparents possédant un troisième indice de réfraction inférieur à la première plage d'indice de réfraction et au deuxième indice de réfraction.
