Abstract

The invention relates to the technical field of display and particularly relates to an organic light emitting display panel, a display device thereof and a manufacturing method thereof. The organic light emitting display panel comprises a substrate, a display layer and a package structure. The package structure includes a film encapsulation layer which at least comprises a first inorganic layer and a first organic layer arranged in order. The surface roughness of the first inorganic layer is 0.01nm to 0.99nm. A transition layer is at least arranged between the first inorganic layer and the first organic layer and comprises a connection unit. The connection unit comprises at least one atom in a group consisting of a metal atom and a non-metal atom and a non-polar group, wherein the non-polar group is used for combining the first organic layer through intermolecular force, the metal atom or the non-metal atom is used for connecting the first inorganic layer through a covalent bond, thus the adhesion between the first inorganic layer and the first organic layer is significantly enhanced, and a stripping phenomenon between film layers is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel, a display device thereof and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED, Organic Light Emitting Diode) has lower power consumption compared with traditional liquid crystal displays due to its own light-emitting function, and also has high brightness and high response speed, and can be made into flexible Display has become the current mainstream device in the display field. [0003] Water vapor and oxygen in the air have a great influence on the lifetime of OLED devices. Therefore, it is necessary to effectively package the OLED device to fully isolate the OLED device from water vapor, oxygen and other components in the atmosphere, which can greatly prolong the service life of the OLED device, thereby prolonging the service life of the display device including the OLED device. ...
