Abstract

The invention discloses a packaging film and a preparation method thereof, an organic light-emitting display panel and a preparation method thereof. In the present invention, by adding a hygroscopic material in the organic layer, even if water and oxygen are mixed in during the manufacturing process of the packaging film and invade into the packaging film along the packaging defect, the hygroscopic material can absorb it and prevent water and oxygen from continuing to invade into the organic material of the display screen. Light-emitting devices, so as to ensure the water and oxygen barrier ability of the organic light-emitting devices, which is conducive to ensuring the normal use of the organic light-emitting devices.

Description

technical field [0001] The invention relates to the technical field of thin film packaging and display, in particular to a packaging film and a preparation method thereof, an organic light-emitting display panel and a preparation method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED, also known as Organic Light-Emitting Diode) display panels have the advantages of low cost, wide viewing angle, high contrast, and bendability, etc., and are currently being used in both small and large sizes. As a result, the liquid crystal display (Liquid Crystal Display, LCD) market share is being continuously encroached on. [0003] Organic light-emitting devices (i.e. OLED 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; A chemical reaction occurs in the hole transport layer, e...
