Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the specific implementation manners of the organic light-emitting display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The film thickness and shape of each layer in the drawings do not reflect the real scale of the organic light-emitting display panel, and the purpose is only to illustrate the content of the present invention.

[0032] At present, the structure of the flexible display device in the related art, such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of a part of the film layer of a flexible display device in the related art. In the display area, a display panel 1 (consisting of a flexible substrate, an OLED device, and a TFE packaging layer, etc.) and a touch panel 2 (consisting of a substrate, a touch p...

Abstract

The invention discloses an organic light-emitting display panel and a display device. A protective layer is generally made of UV glue. Because an organic film clearance zone is arranged between an outermost retaining wall and a protective layer, fluidity of material of the protective layer expands to a clearance area of an organic film, resulting in unflattening and drop in thickness when a bending area is coated with the material of the protective layer. At least one independent blocking structure is arranged between the retaining wall on the outermost side and the protective layer; in this way, when the bending area is coated with the material of the protective layer; the barrier structure closest to the protective layer can reduce the flow expansion of the protective layer material towards the display area. Therefore, it can be guaranteed that the protective layer is flat, the phenomenon that the thickness of the protective layer is suddenly reduced is avoided, the organic light-emitting display panel can improve the adhesive sealing precision of the protective layer, and the mechanical strength of the flexible display panel in the bending process is enhanced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has gradually become the first choice for screens. It has many advantages such as self-illumination, high luminous efficiency, short response time, high definition and contrast, and can also ensure that the screen has certain flexibility and reliability. adaptability. With the development of flexible display screens, people's expectations for foldable display products are getting higher and higher. [0003] Before the flexible display panel is bent, it is necessary to apply UV glue to the bending area to ensure that the circuit wiring in the bending area will not be disconnected. However, due to the certain fluidity of the UV glue, it will The flow towards the display area will cause the UV glue in the bending area to lack glue, which will l...
