The invention provides a flexible display panel and a preparation method for the flexible display panel. The flexible display panel comprises a display area and a bending area, and further comprises aflexible substrate, a driving circuit layer and a light-emitting function layer, wherein the driving circuit layer is formed on one side of the flexible substrate; the light-emitting function layer is formed on one side, far away from the flexible substrate, of the driving circuit layer; the flexible substrate comprises a first flexible layer, a first barrier layer and a second flexible layer; and the first barrier layer comprises a metal oxide located in the display area and a metal and metal oxide lamination located in the bending area. All metals in the display area are oxidized to form the metal oxide, the metal part in the bending area is oxidized to form the metal oxide, in the display area, the metal oxide can play a role in isolating water and oxygen, in the bending area, the metal can improve the bending performance of the display panel, the metal oxide can enhance the stability in the bending state, and the technical problem that the inorganic thin film weakens the flexibility of the flexible substrate is solved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a method for preparing the flexible display panel. Background technique [0002] At present, the most promising polymer material for flexible substrates is polyimide. Due to the weak ability of polyimide to block water and oxygen, a single-layer or multi-layer stacked inorganic film with uniform thickness is usually deposited on its surface, or a multi-layer polyimide / inorganic film alternately stacked structure is used to block Water and oxygen, but the inorganic film has the problems of stress concentration and easy fracture when bent, which weakens the flexibility of the flexible display panel. [0003] Therefore, the existing flexible display panel has the technical problem that the inorganic thin film weakens the flexibility of the flexible substrate, which needs to be improved. Contents of the invention [0004] The invention provides a fle...
