Abstract

A packaging structure, a display component and a display device are provided by the present disclosure. The packaging structure includes: a substrate; a light-emitting unit arranged on the substrate; a packaging layer, by which the light-emitting unit is packaged on the substrate; and a water-absorbing layer which is arranged in the packaging layer and completely wrapped by the packaging layer.

Claims (36)

1. A packaging structure, comprising:

a substrate;

a light-emitting unit arranged on the substrate;

a packaging layer, by which the light-emitting unit is packaged on the substrate; and

a water-absorbing layer which is arranged in the packaging layer and completely wrapped by the packaging layer,

wherein the packaging layer comprises:

a multi-layer composite packaging film covering the light-emitting unit; wherein the multi-layer composite packaging film comprises at least one organic film and at least two inorganic films; the organic film and the inorganic films are arranged alternately; and

an encapsulant layer covering the multi-layer composite packaging film;

the packaging layer further comprises a packaging covering plate, and the encapsulant layer is adhered between the packaging covering plate and the substrate;

the water-absorbing layer is arranged between the organic film and the inorganic film, and is completely wrapped by the organic film and the inorganic film.

2. The packaging structure according to claim 1 , wherein

the water-absorbing layer comprises a base layer and a moisture absorbent located in the base layer.

3. The packaging structure according to claim 2 , wherein

a material of the base layer is the same as or different from a material of the encapsulant layer.

4. The packaging structure according to claim 1 , wherein

the water-absorbing layer is provided with a plurality of grooves, the water-absorbing layer is divided into a plurality of water-absorbing regions spaced apart by the grooves, and the grooves are filled with sealant.

5. The packaging structure according to claim 1 , wherein

the light-emitting unit is an Organic Light-Emitting Diode (OLED) or a Quantum-dot Light-Emitting Diode (QLED).

6. A display component, comprising the packaging structure according to claim 1 .

7. A display device, comprising the display component according to claim 6 .

8. A packaging structure, comprising:

a substrate;

a light-emitting unit arranged on the substrate;

a packaging layer, by which the light-emitting unit is packaged on the substrate; and

a water-absorbing layer which is arranged in the packaging layer and completely wrapped by the packaging layer,

wherein the packaging layer comprises:

a multi-layer composite packaging film covering the light-emitting unit; wherein the multi-layer composite packaging film comprises at least one organic film and at least two inorganic films; the organic film and the inorganic films are arranged alternately; and

an encapsulant layer covering the multi-layer composite packaging film;

the packaging layer further comprises a packaging covering plate, and the encapsulant layer is adhered between the packaging covering plate and the substrate;

the water-absorbing layer has two layers, wherein one layer of the water-absorbing layer is arranged between the organic film and the inorganic film, and is completely wrapped by the organic film and the inorganic film, and the other layer of the water-absorbing layer is arranged on a surface of the packaging covering plate facing the substrate, and is completely wrapped by the packaging covering plate and the encapsulant layer.

9. A packaging structure, comprising:

a substrate;

a light-emitting unit arranged on the substrate;

a packaging layer, by which the light-emitting unit is packaged on the substrate; and

a water-absorbing layer which is arranged in the packaging layer and completely wrapped by the packaging layer,

wherein the water-absorbing layer is provided with a plurality of grooves, the water-absorbing layer is divided into a plurality of water-absorbing regions spaced apart by the grooves, and the grooves are filled with sealant.
