Embodiment Construction

[0019] As mentioned in the background art, there are technical problems in the prior art that the thin film encapsulation layer of the flexible display panel is easily broken when bent or delaminated between layers, resulting in black spots on the screen and other display defects. The reason why such a problem arises is as follows. The existing thin film encapsulation layer adopts sequentially laminated organic encapsulation layer and inorganic encapsulation layer. Since the elastic modulus of the inorganic material itself is lower than that of the organic material, during the bending or folding process of the flexible display panel, the bending stress is mostly concentrated in the inorganic encapsulation layer. layer, the thicker the inorganic encapsulation layer, the greater the stress it suffers, and the easier it is to break or delaminate. However, if the inorganic encapsulation layer is too thin, it will affect the encapsulation effect, especially if the inorganic encapsu...

Abstract

The present invention provides a display panel, the flexible display panel is divided into a bending area and a non-bending area, wherein the thin film encapsulation layer includes a first inorganic encapsulation layer, a second an organic encapsulation layer and a second inorganic encapsulation layer; wherein, the first inorganic encapsulation layer comprises: a first inorganic encapsulation layer located in the bending area of ​​the bending area and a first inorganic encapsulation layer located in the non-bending area of ​​the non-bending area Inorganic encapsulation layer; wherein, the first inorganic encapsulation layer in the bending area further comprises: the first sub-inorganic encapsulation layer in the bending area stacked in sequence along the direction away from the substrate; and the second sub-inorganic encapsulation layer in the bending area, so The second sub-inorganic encapsulation layer in the bending area includes at least two inorganic encapsulation blocks arranged at intervals, and the orthographic projection of the at least two inorganic encapsulation blocks on the substrate covers a plurality of the light-emitting elements located in the bending area The orthographic projection of the cell on the substrate. In order to improve the bending resistance of the flexible display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel, a manufacturing method thereof, and a flexible display terminal. Background technique [0002] With the continuous development of flexible display technology, users have higher and higher requirements for the stability of the performance of flexible display products and the number of times of bending resistance. In the process of bending or folding, film layers such as the thin film encapsulation layer in the flexible display panel are affected by the bending stress, and the film layer is often prone to breakage or interlayer peeling, resulting in black spots and other display defects. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a flexible display panel to solve the technology that the thin film encapsulation layer of the flexible display panel in the prior art is easy to break when it i...
