Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.
[0034] At the same time, the drawings and descriptions of the embodiments are illustrative rather than restrictive. The same reference numbers refer to the same elements throughout the specification. Additionally, the thickness of some layers, films, panels, regions, etc., may be exaggerated in the drawings for understanding and ease of description. It will also be understood that when an element such as a layer, film, region or substrate is referred to as being "on" another element, it can be directly on the other element or int...

The invention discloses a flexible organic light-emitting display panel and a display device. The flexible organic light emitting display panel includes: a flexible substrate; a thin film transistor layer on the flexible substrate; an organic light emitting diode layer on the thin film transistor layer; a package structure on the organic light emitting diode layer; A barrier layer disposed around the organic light emitting diode layer; wherein the barrier layer includes a first barrier structure, a second barrier structure and a plurality of supplementary barrier structures, the first barrier structure is disposed around the organic light emitting diode layer, and the second barrier structure surrounds The first blocking structure is provided, and there is a gap between the first blocking structure and the second blocking structure, and a plurality of supplementary blocking structures are arranged at intervals in the gap. The flexible organic light emitting display panel can enhance the adhesion between film layers of the flexible organic light emitting display panel, and improve the stability of the flexible organic light emitting display panel.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a flexible organic light-emitting display panel and a display device. Background technique [0002] The flexible organic light-emitting display panel is a variable and bendable display device, which has the advantages of being easy to carry and can be bent and rolled, so it is a hot spot of research and development in the current display technology. [0003] The organic light-emitting diode (Organic Light-Emitting Diode, OLED) layer of the existing flexible organic light-emitting display panel can usually be fabricated by evaporation technology, wherein the evaporation technology is to perform electron beam bombardment heating and laser heating on electric current in a vacuum environment, etc. , to evaporate the material to be evaporated into atoms or molecules, and then make them move in a straight line, collide with the surface of the substrate and c...
