Title
(EN) DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE
(ZH) 一种显示面板
Abstract
(EN)
Disclosed in the present invention is a display panel. The display panel comprises multiple thin-film layers. Recesses and protrusions are respectively arranged at surfaces of at least two adjacent thin-film layers in the multiple thin-film layers, and the protrusion fits the recesses. A tip end of the protrusion has a diameter greater than a diameter of a root portion of the protrusion. The recess is shaped such that an internal space thereof matches the shape of the protrusion. The above arrangement improves bonding between thin-film layers in a display panel, such that the thin-film layers do not separate easily in a process of bending the display panel, thereby extending service life of the display panel.
(FR)
La présente invention concerne un panneau d'affichage. Le panneau d'affichage comprend de multiples couches de film mince. Des évidements et des saillies sont respectivement agencés au niveau de surfaces d'au moins deux couches de film mince adjacentes dans les multiples couches de film mince, et la saillie s'adapte aux évidements. Une extrémité de pointe de la saillie présente un diamètre supérieur à un diamètre d'une partie racine de la saillie. L'évidement est formé de telle sorte qu'un espace interne de celui-ci correspond à la forme de la saillie. L'agencement ci-dessus améliore la liaison entre des couches de film mince dans un panneau d'affichage, de telle sorte que les couches de film mince ne se séparent pas facilement dans un processus de pliage du panneau d'affichage, prolongeant ainsi la durée de vie du panneau d'affichage.

本申请公开了一种显示面板。该显示面板包括:多层薄膜层;其中,多层薄膜层中至少两相邻薄膜层的层表面分别具有凹陷和凸起,凹陷和凸起之间凹凸啮合,凸起端部直径大于根部直径,凹陷内空间形状与凸起外形匹配。通过上述方式,本申请能够提高显示面板中薄膜层之间的结合力,进而使得显示面板在弯折时薄膜层不易剥离,提高了显示面板的使用寿命。
