Abstract
(EN) Embodiments of the present invention provide a display substrate, a display device, and a detection method for the display substrate. The display substrate comprises: a substrate, comprising a display area and a peripheral area located on at least one side of the display area; a crack blocking member located in the peripheral area, the crack blocking member being configured to block a crack from extending toward the display area; a packaging structure provided on the substrate and covering the display area; and a crack detection structure provided on the substrate, wherein the crack detection structure is located on the side of the crack blocking member close to the display area, the orthographic projection of the crack detection structure on the substrate falls into the orthographic projection of the packaging structure on the substrate, and the crack detection structure is configured to detect whether a crack occurs in the packaging structure.
(FR) Certains modes de réalisation de la présente invention concernent un substrat d'affichage, un dispositif d'affichage et un procédé de détection pour le substrat d'affichage. Le substrat d'affichage comprend : un substrat, comprenant une zone d'affichage et une zone périphérique située sur au moins un côté de la zone d'affichage ; un élément de blocage de fissures situé dans la zone périphérique, l'élément de blocage de fissures étant configuré pour bloquer une fissure de s'étendre vers la zone d'affichage ; une structure d'encapsulation disposée sur le substrat et recouvrant la zone d'affichage ; et une structure de détection de fissures disposée sur le substrat, la structure de détection de fissures étant située sur le côté de l'élément de blocage de fissures à proximité de la zone d'affichage, la projection orthographique de la structure de détection de fissures sur le substrat tombe dans la projection orthographique de la structure d'encapsulation sur le substrat, et la structure de détection de fissures est configurée pour détecter si une fissure se produit dans la structure d'encapsulation.
(ZH) 本公开的实施例提供一种显示基板,一种显示装置,以及一种用于显示基板的检测方法。所述显示基板包括:衬底基板,所述衬底基板包括显示区和位于所述显示区至少一侧的外围区;位于所述外围区中的裂纹阻挡件,所述裂纹阻挡件被配置为阻挡裂纹朝所述显示区延伸;设置于所述衬底基板上且覆盖所述显示区的封装结构;以及设置于所述衬底基板上的裂纹检测结构,其中,所述裂纹检测结构位于所述裂纹阻挡件靠近所述显示区的一侧,所述裂纹检测结构在所述衬底基板上的正投影落入所述封装结构在所述衬底基板上的正投影内,所述裂纹检测结构被配置为检测所述封装结构中是否出现裂纹。
