Embodiment Construction

[0039] The specific implementation manners of the flexible display panel provided by the embodiments of the present invention, its manufacturing method and the display device will be described in detail below with reference to the accompanying drawings.

[0040] A method for manufacturing a flexible display panel provided by an embodiment of the present invention specifically includes:

[0041] An organic luminescent functional film layer and an encapsulation film covering the organic luminescent functional film layer are formed on the flexible substrate; wherein the encapsulation film includes alternately arranged multi-layer inorganic films and at least one organic film;

[0042] After forming the first layer of inorganic film in the encapsulation film, it also includes:

[0043] removing the pattern of the first layer of inorganic thin film at the via hole region;

[0044] removing the pattern of the organic light-emitting functional film layer at the through hole area by ...

Abstract

The invention discloses a flexible display panel and a making method thereof and a display device. The making method comprises the steps that after a first layer of inorganic thin film in an encapsulated thin film is formed, the pattern of the portion, in a through hole area, of the first layer of inorganic thin film is removed, and the patterns of the other portions of the first layer of inorganic thin film are used for masking so as to remove the pattern of the portion, in the through hole area, of an organic luminous functional film layer, so that an overhead through hole area masking partin an evaporation mask is replaced, and the aim that there are no patterns of the organic functional film layer in the through hole area is achieved. The inorganic thin film which is subsequently formed in the encapsulated thin film can achieve an encapsulation effect on the organic luminous functional film layer in the through hole area, and the airtightness of the flexible display panel in the through hole area is ensured so as to prevent the failure of a displayer. After the last layer of inorganic thin film is formed in the encapsulated thin film, the step that the pattern of the portion,in the through hole area, of the last layer of inorganic thin film is removed is added, and the effect that a through hole is formed in the flexible display panel is achieved after a flexible substrate in the through hole area is removed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel, a manufacturing method thereof and a display device. Background technique [0002] With the development of display technology, the full screen has a large screen-to-body ratio and an ultra-narrow bezel. Compared with ordinary display screens, it can greatly improve the visual effect of the viewer, and thus has received widespread attention. At present, in a display device such as a mobile phone with a full screen, in order to realize the functions of Selfie, video call and fingerprint recognition, a front camera, an earpiece, a fingerprint recognition device or physical buttons are usually arranged in the display area. [0003] Currently, in order to satisfy the flexibility of flexible display screens, organic light-emitting display panels are generally used to manufacture flexible display screens. In order to realize a full screen on the flexible disp...
