Problems solved by technology

However, when the bending angle of the curved surface area of ​​the glass cover plate is larger, stress concentration will occur in the curved surface area, resulting in greater stress on the film layer located on the curved surface of the glass cover plate, resulting in the metal wiring inside the panel, inorganic Defective phenomena such as peeling and cracking between layers and other film layers

Abstract

The invention discloses a flexible substrate, a display panel and a display device. The flexible substrate comprises a plane area and at least one curved surface area extending towards a first direction along the edge of the plane area; each curved surface area comprises a plurality of through hole groups, the through hole groups at least comprise a first through hole group arranged along the curved surface center line of the curved surface area, and the first through hole group comprises a plurality of through holes which are arranged at intervals and penetrate through the flexible substrate; the orthographic projection of the center line of each through hole on the upper surface of the plane area coincides with the center line of the curved surface. The curved surface area of the flexible substrate is provided with a plurality of through hole groups, so that the stress borne by the corresponding display panel when the display panel is attached to the curved surface area of the large-angle curved surface glass cover plate is reduced, and the undesirable phenomena such as peeling and cracking among metal wires, an inorganic layer and other film layers in the display panel are avoided.

Description

technical field [0001] The present application relates to the display field, in particular to a flexible substrate, a display panel and a display device. Background technique [0002] During the research and practice of the prior art, the inventors of the present application found that with the maturity of OLED (Organic Light-Emitting Diode, organic electroluminescent device) display technology, more and more flexible OLED display products, flexible The curved area screen design brought by OLED has improved the screen-to-body ratio qualitatively, and consumers have more and more demands for flexible OLED curved area screen display modules. [0003] In the prior art, the flexible substrate and other module materials are attached to the curved glass cover to form a flexible curved display. Generally speaking, when the bending angle of the left and right curved surfaces of the curved glass cover is larger, the left and right borderless effects will be greater. The better, for ...
