US Patent 11195859 Array substrate and flexible display panel

An array substrate and a flexible display panel are provided. The array substrate is in a bending region and includes a base; an inorganic layer formed on the base, wherein at least one hollowing-out region is disposed in the inorganic layer, and the hollowing-out region is non-filled or filled with an organic matter; and a metal layer formed on the inorganic layer and connected to layers on a bottom of the inorganic layer by at least one via hole encircled by the at least one hollowing-out region. When the flexible display panel is bent, the at least one hollowing-out region provides a good channel for releasing stress in the inorganic layer and improves the bending performance of the flexible display panel.
