Zusammenfassung:A tandem OLED display is provided, including a substrate backplane, an anode layer, at least two stacked OLED layers, each OLED layer comprising a plurality of pixels, at least one charge generation layer (CGL), wherein each CGL is disposed between two adjacent stacked OLED layers, and a cathode layer. At least one of the CGLs is patterned wherein a pattern provides gaps between each of the plurality of pixels. L'invention concerne un affichage OLED en tandem, comprenant un fond de panier de substrat, une couche d'anode, au moins deux couches OLED empilées, chaque couche OLED contenant une pluralité de pixels, au moins une couche de génération de charge (CGL), chaque CGL étant disposée entre deux couches OLED empilées adjacentes, et une couche de cathode. Au moins l'une des CGL porte des motifs, un motif définissant des espaces entre chaque pixel de la pluralité de pixels.
