Abstract

The invention provides a flexible display panel and a preparation method thereof and a curved display screen, and solves the problem that a metal layer is liable to break or a film layer is liable toseparate after the flexible display panel is frequently bent in the prior art. The flexible display panel includes a plurality of film layers sequentially stacked on a flexible substrate in a first direction. The flexible display panel is characterized in that a plurality of film layers include: an inorganic layer including a groove filled with an organic material; and the metal layer located in the opening direction of the groove of the inorganic layer, wherein the metal layer comprises a through hole, and the orthographic projection of the through hole on the inorganic layer at least partially coincides with the groove.

Description

technical field [0001] The invention relates to the technical field of flexible display, in particular to a flexible display panel, a preparation method thereof, and a curved display screen. Background technique [0002] With the development of the information society, flexible display panels are more and more widely used in display devices. The flexible display panel has good flexibility. Therefore, the edge area of ​​the flexible display panel can be placed under the display screen by bending to achieve a narrow frame; or the large-size display can be folded into a small size by folding. ,easy to carry. [0003] However, since the bending area usually adopts a multi-layered film structure, the film layers are easily separated during bending, and the metal wires in the bending area are likely to break during the bending process, thereby reducing the reliability of the display screen. Contents of the invention [0004] In view of this, the embodiments of the present inve...
