Abstract
(EN)
A display substrate including a plurality of light emitting elements respectively in a plurality of subpixels configured to emit light for image display is provided. A respective one of the plurality of subpixels includes a base substrate; a first auxiliary cathode; a passivation layer; a first insulating layer; a second auxiliary cathode; a second insulating layer; and a pixel definition layer. The display substrate has a cathode aperture extending through the pixel definition layer and an auxiliary cathode aperture extending through the first insulating layer and the passivation layer. A cathode of a respective one of the plurality of light emitting elements extends into the cathode aperture to electrically connect with the second auxiliary cathode. The second auxiliary cathode extends into the auxiliary cathode aperture to electrically connect with the first auxiliary cathode.

L'invention concerne un substrat d'affichage comprenant une pluralité d'éléments électroluminescents respectivement dans une pluralité de sous-pixels conçus pour émettre de la lumière pour un affichage d'image. Un sous-pixel respectif de la pluralité de sous-pixels comprend un substrat de base; une première cathode auxiliaire ; une couche de passivation ; une première couche isolante ; une seconde cathode auxiliaire ; une seconde couche isolante ; et une couche de définition de pixels. Le substrat d'affichage comporte une ouverture de cathode s'étendant dans la couche de définition de pixels et une ouverture de cathode auxiliaire s'étendant dans la première couche isolante et la couche de passivation. Une cathode d'un élément respectif de la pluralité d'éléments électroluminescents s'étend dans l'ouverture de cathode pour se connecter électriquement à la seconde cathode auxiliaire. La seconde cathode auxiliaire s'étend dans l'ouverture de cathode auxiliaire pour se connecter électriquement à la première cathode auxiliaire.
