Problems solved by technology

When the module material with viscoelastic or viscoplastic properties in the display panel is folded, each film layer is squeezed or stretched by an external force, which will cause different layers to slip due to mismatched film materials, resulting in the appearance of the display panel. Creases affect the display effect

Embodiment Construction

[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0067] As mentioned in the background art, with the development of display panels in a bendable direction, flexible display screens have attracted more and more attention. Display screens of new technologies, such as Foldable screens, Rollable screens, etc., have begun to appear. Among them, when a certain thickness of the module material with viscoelasticity or viscoplasticity is folded, it will be squeezed or stretched by external force, which will cause the phenomenon of mismatched film material slip between different layers. ...

Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device. The display panel includes: a foldable area; a first stress buffer layer; the first stress buffer layer includes a first stress buffer structure, the first stress buffer structure is located in the foldable area, the first stress buffer structure It includes a plurality of grooves formed on the first stress buffer layer; the inner surface of the groove includes a plurality of protrusions. The embodiments of the present invention can buffer the stress of the film layer when the display panel is folded, thereby reducing the unevenness of the crease caused by the folding of the display panel, ensuring the display effect and improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, the display panel is constantly developing from thin to thinner, from narrow frame to frameless, and from inflexible to bendable. When the module material with viscoelastic or viscoplastic properties in the display panel is folded, the extrusion or stretching of each film layer by external force will cause the film slippage of different layers due to mismatch, resulting in the appearance of the display panel. Creases affect the display effect. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device, so as to buffer the stress of the film layer when the display panel is folded, thereby reducing the unevenness of the ...
