Embodiment 1

[0032] refer to figure 1 , which shows a schematic structural view of a packaging cover plate described in Embodiment 1 of the present application, specifically including:

[0033] A base substrate 1, the base substrate 1 includes a display area and a packaging area arranged around the display area.

[0034] In the direction from the display area to the encapsulation area, an encapsulation layer 2 , a first barrier layer 3 , a water absorbing layer 4 and a second barrier layer 5 are sequentially arranged in the encapsulation area of ​​the base substrate.

[0035] Specifically, the encapsulation layer 2 may be formed in the encapsulation area of ​​the base substrate in a direction from the display area to the encapsulation area by using a gluing machine. Then, the first barrier layer 3, the water-absorbing layer 4 and the second barrier layer 5 are formed by using a glue coating machine.

[0036] Wherein, the material of the base substrate can be a glass substrate, a plastic ...

Embodiment 2

[0050] The present application also discloses a display panel, including a display substrate 6 arranged on the box and the packaging cover in Embodiment 1, such as figure 2 shown.

[0051] The display panel has all the advantages of the encapsulation cover plate in the first embodiment above, which will not be repeated here.

Embodiment 3

[0053] The present application also discloses a display device, including the display substrate in the second embodiment.

[0054] The display device has all the advantages of the display substrate in the second embodiment above, and will not be repeated here.

Abstract

The present application provides a package cover plate, a display device, a display panel, and a packaging method of a display panel. The package cover plate comprises a substrate; the substrate includes a display area and a package area disposed at the periphery of the display area; in a direction from the display area to the package area, the package area of the substrate is internally providedwith a package layer, a first barrier layer, a water absorbing layer and a second barrier layer in order, and therefore, the problem that the display of the display panel is poor caused by the external water vapor is solved in the prior art.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a packaging cover plate, a display device, a display panel and a packaging method for the display panel. Background technique [0002] With the vigorous development of display technology, organic light emitting diode (Organic Light Emitting Diode, OLED), as a current-type light-emitting device, is favored because of its self-luminescence, fast response, wide viewing angle and flexible display. It is increasingly being used in the field of high-performance display. [0003] The existing encapsulation cover includes: a substrate, a barrier layer and an encapsulation layer. However, due to the limited water resistance of the barrier layer and the encapsulation layer, external water vapor will penetrate into the interior of the display panel, resulting in poor display of the display panel. Contents of the invention [0004] The present application provides a packaging c...
