Embodiment Construction

[0025] As mentioned in the background art, flexible display panels in the prior art are prone to poor display after repeated bending. The inventors found that the reason for this problem is that the array module in the flexible display panel includes multiple layers Inorganic insulating layer, and when the flexible display panel is repeatedly bent, the inorganic insulating layer is prone to cracks or breaks due to bending stress, resulting in poor display of the flexible display panel.

[0026] Based on this, the present invention provides a flexible display panel. By arranging an inorganic insulating layer only in the transistor structure and the capacitor structure in the flexible display panel, the area of ​​the inorganic insulating layer in the flexible display panel is reduced, and the energy consumption of the flexible display panel is reduced. After repeated bending, the probability of cracks or fractures in the inorganic insulating layer due to the bending stress reduce...

Abstract

The embodiment of the invention provides a flexible display panel, a preparation method thereof and a flexible display device. The technical problem that in the prior art, a flexible display panel ispoor in display after being folded multiple times is solved. According to the flexible display panel provided by the embodiment of the invention, an inorganic insulating layer is only arranged in a transistor structure and a capacitor structure in the flexible display panel, the area of the inorganic insulating layer in the flexible display panel is reduced, the probability that the inorganic insulating layer is cracked or broken due to bending stress after the flexible display panel is bent for multiple times is reduced, and the probability that the flexible display panel is poor in display is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel, a preparation method thereof, and a flexible display device. Background technique [0002] With the development of display technology, display devices are now widely used in a wide range of applications, so the performance requirements for panels are gradually increasing. The flexible screen has the characteristics of being bendable. By utilizing the flexibility of the display device, people can bend or fold the display device, thereby bringing convenience to people to carry and use the display device. [0003] At present, the flexible display screen has become an important development direction of the display screen of electronic equipment due to its advantages of being bendable and portable; however, although the foldable flexible display panel in the prior art can be folded, it cannot be After bending, the display panel has a poor display phenomenon...
