Abstract
(EN)
The present application provides a display panel, a display device, and a method for manufacturing a substrate for the display panel. The display panel comprises a substrate comprising an organic film layer, an inorganic film layer, and a metal layer which are successively stacked; the substrate is divided into a display region and a bending region connected to at least part of the edge of the display region; an opening is formed in the metal layer in the bending region, the opening extends into the inorganic film layer, and the opening divides the metal layer into a plurality of metal wires. The display panel, the display device, and the method for manufacturing a substrate for the display panel provided by the present application prevent the metal wires on both sides of the opening from being connected to each other to cause a short circuit, and reduce the thickness of the inorganic film layer at the opening position, thereby improving the flexibility of the display panel, preventing a crack from extending between the metal layers on both sides of the opening, and improving the reliability of the display panel and the display device.

L'invention concerne un panneau d'affichage, un dispositif d'affichage et un procédé de fabrication d'un substrat pour le panneau d'affichage. Le panneau d'affichage comprend un substrat comprenant une couche de film organique, une couche de film inorganique et une couche métallique qui sont empilées successivement ; le substrat est divisé en une région d'affichage et une région de courbure reliée à au moins une partie du bord de la région d'affichage ; une ouverture est formée dans la couche métallique dans la région de courbure, l'ouverture s'étend dans la couche de film inorganique, et l'ouverture divise la couche métallique en une pluralité de fils métalliques. Le panneau d'affichage, le dispositif d'affichage et le procédé de fabrication d'un substrat pour le panneau d'affichage selon la présente invention empêchent les fils métalliques des deux côtés de l'ouverture d'être reliés l'un à l'autre pour provoquer un court-circuit, et réduisent l'épaisseur de la couche de film inorganique au niveau de la position d'ouverture, ce qui permet d'améliorer la flexibilité du panneau d'affichage, empêcher une fissure de s'étendre entre les couches métalliques des deux côtés de l'ouverture, et améliorer la fiabilité du panneau d'affichage et du dispositif d'affichage.

本申请提供一种显示面板、显示装置及制作用于显示面板的基板的方法。该显示面板包括基板,基板包括依次层叠设置的有机膜层、无机膜层以及金属层;基板划分为显示区以及连接在显示区的至少部分边缘处的弯折区;弯折区内的金属层上形成有开口,开口延伸至无机膜层内,并且开口将金属层划分成多条金属走线。本申请提供的显示面板、显示装置及制作用于显示面板的基板的方法,避免了开口两侧的金属走线相互连接而发生短路,并且降低了开口位置处的无机膜层的厚度,提高了显示面板柔性,避免了裂纹在开口两侧的金属层之间发生扩展,提高了显示面板及显示装置的可靠性。
