Title (EN) ELECTROLUMINESCENT DISPLAY
(FR) DISPOSITIF D'AFFICHAGE ÉLECTROLUMINESCENT
Abstract:
(EN) An electroluminescent display is disclosed. The electroluminescent display includes pixels including light emitting elements configured to emit light, a bank configured to partition the pixels, and a light extraction member accommodated inside the bank. A refractive index of the bank is different from a refractive index of the light extraction member. Each light emitting element includes a first electrode, a second electrode, and an organic compound layer between the first electrode and the second electrode. The light extraction member is positioned on a side of the first electrode. A maximum thickness of the light extraction member is greater than a sum of thicknesses of the first electrode, the organic compound layer, and the second electrode.
(FR) Cette invention concerne un dispositif d'affichage électroluminescent. Le dispositif d'affichage électroluminescent comprend des pixels comprenant des éléments électroluminescents configurés pour émettre de la lumière, une barrette configurée pour diviser les pixels, et un élément d'extraction de lumière logé à l'intérieur de la barrette. Un indice de réfraction de la barrette peut être différent d'un indice de réfraction de l'élément d'extraction de lumière. Chaque élément électroluminescent comprend une première électrode, une seconde électrode et une couche de combinaison organique entre la première électrode et la seconde électrode. L'élément d'extraction de lumière est positionné sur un côté de la première électrode. Une épaisseur maximale de l'élément d'extraction de lumière est supérieure à une somme des épaisseurs de la première électrode, de la couche de combinaison organique et de la seconde électrode.
