Embodiment Construction

[0018] A primary purpose of the present invention is: by adding an auxiliary encapsulation layer on the outside of the inorganic material layer, and the auxiliary encapsulation layer covers at least the bending area and the boundary area of ​​the inorganic material layer, that is to say, where the inorganic material layer is most prone to fracture Or the peeled bending area and the boundary area add an auxiliary encapsulation layer, even if the inorganic layer breaks or peels in the bending area and the boundary area, the water and oxygen channel generated at the break or peeling will be blocked by the auxiliary encapsulation layer , so as to ensure that the encapsulation film still has a strong water and oxygen barrier ability to the organic light-emitting device.

[0019] The technical solutions provided by the various exemplary embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present inve...

Abstract

The invention discloses an organic light-emitting display panel, a manufacturing method thereof and a packaging film. According to the invention, an auxiliary packaging layer is additionally arranged at the outer side of the inorganic matter layer; and the auxiliary packaging layer at least covers a bending area and a boundary area of the inorganic substance layer. Even if the inorganic substance layer is broken or stripped in the bending area and the boundary area, a water-oxygen channel generated at the broken or stripped part can be blocked by the auxiliary packaging layer, so that the water-oxygen blocking capability of the packaging film to the organic light-emitting device is ensured.

Description

technical field [0001] The present invention relates to the field of organic light-emitting (Organic Light-Emitting Diode, OLED) display, in particular to an organic light-emitting display panel, a manufacturing method thereof, and an encapsulation film. Background technique [0002] Organic light-emitting display panels have the advantages of low cost, wide viewing angle, high contrast ratio, and bendability. At present, they have achieved remarkable results in small-size and large-size applications, and are constantly encroaching on the liquid crystal display (Liquid Crystal Display, LCD) market. market share. [0003] Organic light-emitting devices are an important part of organic light-emitting display panels, and water and oxygen have a great impact on their life. First, it is easy to react with the conductive material of the cathode of the organic light-emitting device; second, it is easy to react with the hole transport layer of the organic light-emitting device A ch...
