Display panel and preparation method thereof, and display device

Abstract

The application discloses a display panel and a preparation method thereof, and a display device, and relates to the technical field of the display. A bending area and a non-bending area a provided, the display panel comprises at least one substrate, and a driving function layer, a light-emitting function layer and a package layer which are orderly arranged on the substrate along a direction far away from the substrate; the substrate comprises a first flexible base plate, and a first nano-film and a buffer layer orderly arranged on the first flexible base plate along a direction vertically faraway from the first flexible base plate, wherein the buffer layer is located at one side, close to the driving function layer, of the first nano-film, and comprises a first buffer layer located at the bending area and a second buffer layer located at the non-bending area, the first buffer layer and the second buffer layer are arranged at the same layer and have the same thickness, and the first buffer layer comprises organic materials. Therefore, the completeness of the first flexible base plate can be guaranteed, and the bending resistance of the display panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED) has become a very popular flat-panel display industry at home and abroad, and is hailed as the next-generation "star" flat-panel display technology, mainly because OLED has low power consumption. , Self-illumination, wide viewing angle, fast response time, high luminous efficiency, thin panel thickness, large-size and bendable panels can be produced, simple manufacturing process, and low cost. In addition, display devices with foldable performance are convenient to carry, and are an important development direction of display devices in the future. [0003] The existing foldable display panel can be opened and closed like a book, and has the advantages of small space occupation and convenient portability. At present...

AI Technical Summary

Problems solved by technology

However, multiple small flexible display screens are spliced ​​together to form a foldable display panel, and then applied to large display devices. This splicing method is aimed at small display devices, such as mobile phones, tablet computers, etc. The effect is not ideal, which affects the display effect of the entire display panel

[0004] In addition, when the display panel is a flexible display panel, the bending reliability of the display panel is poor, and the repeated folding is easy to crack or even break, resulting in failure problems such as short circuit in the circuit, which affects the normal display of the display panel.
