Adhesive film, packaging method of display panel and display device

Abstract

The invention provides an adhesive film, a packaging method of a display panel and a display device, and relates to the technical field of displaying. When the adhesive film is applied to packaging, the phenomenon that a main body adhesive layer and a packaging film are separated during stripping of a protective layer on the surface of the main body adhesive layer can be avoided, so that the production progress and the product yield can be improved. The adhesive film comprises the main body adhesive layer, a buffer adhesive layer and a first protective layer which are arranged in sequence along a thickness direction, wherein the side, away from the buffer adhesive layer, of the main body adhesive layer is fitted to the packaging film; the buffer adhesive layer is made of an adhesive material, and the viscosity of the adhesive material is reduced after the adhesive material is irradiated by ultraviolet rays; and the first protective layer is made of an ultraviolet ray-permeable adhesivematerial. The adhesive film is applied to packaging the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adhesive film, a packaging method of a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic electroluminescent diode) panels are distributed with many light-emitting devices for display, because these light-emitting devices are corroded by water vapor and oxygen (ie water oxygen) in the environment, which will affect their luminous performance , therefore, the OLED panel needs to be packaged. [0003] In the existing packaging technology, since the metal film used in the metal packaging process has better water and oxygen barrier performance and is conducive to realizing the lightness and thinning of the display device, it occupies a dominant position in the packaging technology. The main process of the metal packaging process is: peel off the protective film on one side of the adhesive film surface to expose one side ...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, after the adhesive film is pasted on the metal film, due to the strong adhesion between the protective film on the other side and the adhesive film, it is easy to make the protective film part or all of the adhesive film when peeling off. This will lead to the separation of the adhesive film and the metal film, that is, poor peeling, resulting in waste of materials, and equipment alarms caused by abnormal equipment shutdown, which will affect the production progress and product yield.
