Abstract
(EN)
A display substrate (1) has a display area (DA) and a peripheral area (PA). The display substrate (1) includes a base substrate (10); a first insulating layer (21) on the base substrate (10) and in at least the peripheral area (PA); a plurality of light emitting elements (LE) on the base substrate (10) and in the display area (DA); and an encapsulating layer on a side of the plurality of light emitting elements (LE) distal to the base substrate (10) to encapsulate the plurality of light emitting elements (LE). The encapsulating layer includes a first inorganic encapsulating sublayer (41) extending from the display area (DA) into the peripheral area (PA). The display substrate (1) has a groove (G1) extending into the first insulating layer (21) in the peripheral area (PA), forming a first perimeter substantially surrounding the display area (DA). The first inorganic encapsulating sublayer (41) extends into at least a portion of the groove (G1).
(FR)
L'invention porte sur un substrat d'affichage (1) ayant une zone d'affichage (DA) et une zone périphérique (PA). Le substrat d'affichage (1) comprend un substrat de base (10) ; une première couche isolante (21) sur le substrat de base (10) et dans au moins la zone périphérique (PA) ; une pluralité d'éléments électroluminescents (LE) sur le substrat de base (10) et dans la zone d'affichage (DA) ; et une couche d'encapsulation sur un côté de la pluralité d'éléments électroluminescents (LE) distal par rapport au substrat de base (10) pour encapsuler la pluralité d'éléments électroluminescents (LE). La couche d'encapsulation comprend une première sous-couche d'encapsulation inorganique (41) s'étendant à partir de la zone d'affichage (DA) dans la zone périphérique (PA). Le substrat d'affichage (1) comporte une rainure (G1) s'étendant dans la première couche isolante (21) dans la zone périphérique (PA), formant un premier périmètre entourant sensiblement la zone d'affichage (DA). La première sous-couche d'encapsulation inorganique (41) s'étend dans au moins une partie de la rainure (G1).
