Problems solved by technology

[0002] like figure 1 As shown, the existing flexible display panel generally includes a flexible display substrate 1, and an encapsulation structure 2 arranged on the surface of the flexible display substrate, so as to use the encapsulation structure 2 to reduce the water vapor and oxygen entering the flexible display substrate, thereby protecting the flexible display substrate 1. Light-emitting devices, avoiding the problem of reduced service life of light-emitting devices caused by water vapor and oxygen
[0003] However, since in the prior art, the part of the packaging structure 2 corresponding to the display area of ​​the flexible display substrate 1 is a stacked packaging structure 2A, and the part of the packaging structure 2 corresponding to the non-display area of ​​the flexible display substrate 1 is generally an inorganic packaging structure 2B, Although the laminated packaging structure can well block water vapor and oxygen from entering the flexible display substrate 1, since the inorganic packaging structure 2B is prone to cracks due to bending stress during the bending process of the flexible display device, water vapor and oxygen can pass through the inorganic packaging structure 2B. The cracks on the surface enter the flexible display substrate, resulting in a reduction in the service life of the light-emitting device in the flexible display substrate 1

Embodiment 1

[0032] see figure 2 with image 3 , the embodiment of the present invention provides a flexible display panel, including a flexible display substrate 1, and an encapsulation structure 2 arranged on the surface of the flexible display substrate 1, the part of the encapsulation structure 2 corresponding to the non-display area is an inorganic encapsulation structure 2B; the flexible display panel An organic encapsulation layer 3B covering the inorganic encapsulation structure 2B is also included.

[0033] When the flexible display panel is bent, bending stress is generated, and the bending stress is absorbed by the organic encapsulation layer 3B, so that the bending stress acting on the inorganic encapsulation structure 2B is reduced.

[0034] Through the bending process of the flexible display panel provided by this implementation, it can be seen that since the organic encapsulation layer 3B covers the inorganic encapsulation structure 2B, and the organic encapsulation layer ...

Abstract

The invention discloses a flexible display panel, a manufacturing method and a flexible display device, and relates to the technical field of flexible display. The possibility that cracks are generated on an inorganic packaging structure when the flexible display panel is bent is reduced, so that the service life of a luminescent device inside a flexible display substrate is prolonged. The flexible display panel comprises the flexible display substrate and a packaging structure arranged on the surface of the flexible display substrate, and the part, corresponding to a non-display area, of the packaging structure is the inorganic packaging structure; and the flexible display panel also comprises an organic packaging layer with which the inorganic packaging structure is covered. The manufacturing method of the flexible display panel comprises manufacturing the flexible display panel proposed in the technical scheme. The flexible display panel provided by the invention is used in the flexible display device.

Description

technical field [0001] The invention relates to the technical field of flexible display, in particular to a flexible display panel, a manufacturing method, and a flexible display device. Background technique [0002] Such as figure 1 As shown, the existing flexible display panel generally includes a flexible display substrate 1, and an encapsulation structure 2 arranged on the surface of the flexible display substrate, so as to use the encapsulation structure 2 to reduce the water vapor and oxygen entering the flexible display substrate, thereby protecting the flexible display substrate 1. The light-emitting device avoids the problem of reduced service life of the light-emitting device caused by water vapor and oxygen. [0003] However, since in the prior art, the part of the packaging structure 2 corresponding to the display area of ​​the flexible display substrate 1 is a stacked packaging structure 2A, and the part of the packaging structure 2 corresponding to the non-dis...
