Abstract

The invention relates to a package film. The package film comprises: a plurality of inorganic package film layers; at least one superabsorbent organic layer arranged between the inorganic package filmlayers; and a diamond-like film layer arranged between the inorganic package film layers and the superabsorbent organic layer. When water and oxygen invade the package film, the superabsorbent organic layer has a strong ability to absorb water and oxygen, thereby rapidly adsorbing water and oxygen therein, and the diamond-like film layer on the upper and lower sides of the superabsorbent organiclayer has an effect of retaining the wall to form a barrier space for trapping water and oxygen so as to preventing water and oxygen from diffusing and invading and improve the water-oxygen barrier property and packaging reliability of the package film. The present invention further provides a package structure, an organic electroluminescent display panel and a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an encapsulation film, an encapsulation structure, an organic electroluminescent display panel and a display device. Background technique [0002] With the development of technologies such as big data, cloud computing and mobile Internet, human beings have entered the era of intelligence, including smart mobile communication terminals, wearable devices and artificial intelligence and other smart devices, which have become an indispensable part of people's work and life. As an important window for human-computer interaction in the era of intelligence, display panels are also undergoing major changes. Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has the advantages of thin thickness, self-luminous performance, low power consumption, and good flexibility. Flat panel display device. [0003] Since the organic luminescent material in the OLED displ...
