Abstract

The invention discloses an array substrate and an organic luminescent display panel. The array substrate comprises a substrate, an inorganic insulation layer positioned on the substrate, and a metal line layer positioned on the side, far from the substrate, of the inorganic insulation layer. The side, far from the substrate, of the inorganic insulation layer includes multiple projection structures, the metal line layer extends along the projection structures in a climbing way, and the extension length of the metal line layer can be increased substantially via arrangement of the projection structures. Compared with the prior art, the extension length of the metal line layer in the bending direction is increased in the array substrate, the bending radii of the metal line layer is lower, themetal line layer can bear a lower bending radii and is not cracked, and the problem that a metal line is easy to crack during bending in the prior art is solved.

Description

technical field [0001] Embodiments of the present invention relate to flexible panel technology, and in particular to an array substrate and an organic light emitting display panel. Background technique [0002] Active matrix OLED (AMOLED) is a self-luminous display device. AMOLED has better picture quality than liquid crystal display. AMOLED is also a thin-film solid-state device, so this makes it easier to use for flexible displays. [0003] Such as figure 1 Shown is a partial structural diagram of an existing flexible AMOLED, including a glass substrate 10 , a flexible PI film 11 , an inorganic film layer 12 and metal wires 13 . When the flexible AMOLED is bent, the inorganic film layer 12 is prone to rupture due to its internal stress and density, and the corresponding metal wiring 13 on the inorganic film layer 12 may also be broken or disconnected. In addition, the fracture strain limit of the metal itself is about 1%. When the flexible AMOLED is bent, the extension ...
