Embodiment Construction

[0066] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0067] figure 1 is a top view of the display substrate in the first embodiment of the present invention; figure 2 is along figure 1 Sectional view of line AA in .

[0068] refer to figure 1 and figure 2 As shown, the display substrate 1 includes: a display area 1a, an opening area 1b, and an isolation area 1c located between the display area 1a and the opening area 1b; the isolation area 1c is provided with at least one isolation ring surrounding the opening area 1b 40, used to at least cut off the organic light-emitting material layer 17; the partition ring 40 at least includes a support portion 401 and a partition portion 402, and the orthographic projection of the support portion 401 on the plane where the display substrate 1 is l...

Abstract

The invention provides a display device and a display substrate thereof. The display substrate comprises a display area, a porose area, and a partition area between the display area and the porose area. The partition area is provided with at least one partition ring surrounding the porose area, and is used for partitioning an organic light-emitting material layer. The partition ring comprises at least a support portion and a partition portion. The partition portion is provided with a tensile stress layer used for applying tensile stress to the partition portion. When the organic light-emittingmaterial layer is vapor-deposited, partial section of the partition portion in the partition ring is suspended. The partitioning effect on the organic light-emitting material layer is good, and external water and oxygen can be prevented from entering the display area from the opening. In addition, the partition portion can automatically block the organic light-emitting material layer. The use oflaser burning to remove the organic light-emitting material layer around the porose area is avoided. A hot process is omitted. The spacing between the porose area and the display area is shortened. The border of the porose area is reduced. Third, the tensile stress layer can apply tensile stress to the partition portion to prevent the suspended partition portion from collapsing and falling off. The partitioning performance of the partition portion is reliable.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display device and a display substrate thereof. Background technique [0002] With the rapid development of display devices, users have higher and higher requirements for screen-to-body ratio. Since cameras, sensors, earpieces and other components need to be installed above the screen, an opening area is usually reserved above the screen in the prior art for Install the above components, such as the front notch area of ​​the Apple mobile phone iphoneX. [0003] However, the frame of the opening area is relatively large, which is not conducive to improving the screen ratio of the display device. Contents of the invention [0004] The object of the present invention is to provide a display device with a large screen-to-body ratio and a display substrate thereof. [0005] To achieve the above object, the first aspect of the present invention provides a display ...
