Embodiment Construction

[0023] The primary purpose of the present invention is: by adding an auxiliary encapsulation layer on at least one side of the inorganic layer, and the auxiliary encapsulation layer covers the orthographic projection area of ​​the support pillars on the pixel definition layer, even if the inorganic matter layer breaks when covering the support pillars, The water and oxygen channel at the break will also be blocked by the auxiliary encapsulation layer, so as to ensure the water and oxygen barrier ability of the encapsulation film to the organic light-emitting device.

[0024] The following will clearly and completely describe the technical solutions of each exemplary embodiment provided by the present invention with reference to the accompanying drawings in the embodiments of the present invention. In the case of no conflict, the following embodiments and technical features thereof can be combined with each other.

[0025] The direction terms mentioned in the present invention,...

Abstract

The invention discloses an organic light-emitting display panel and a manufacturing method thereof, and a packaging film. According to the invention, an auxiliary packaging layer is additionally arranged on at least one side of a first inorganic layer, and the auxiliary packaging layer covers an orthographic projection area of a support pillar on a pixel definition layer, so that even if the inorganic layer is broken when covering the support pillar, a water-oxygen channel generated at a broken portion can be blocked by the auxiliary packaging layer, and the water-oxygen blocking capability ofthe 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...
