Display substrate

Abstract

The invention discloses a display substrate which is provided with a hole area, a partition area and a display area, the partition area is at least partially arranged around the hole area, the partition area is located between the hole area and the display area, and the display substrate comprises a substrate body, a display function part arranged on one side of the substrate in the display area and comprising a first luminescent material layer, and a partition assembly arranged in the partition area; the partition assembly and the display function part are arranged in a spaced mode, the partition assembly comprises at least one partition wall, and each partition wall comprises a first partition part and a second partition part which are stacked in the film layer stacking direction of thedisplay substrate; the sides, away from the substrate body, of the second partition parts are covered with second light-emitting material layers, and the portions, exposed by the intervals between thesecond partition parts, of the first partition parts are covered with third light-emitting material layers. By arranging the first partition parts and the second partition parts which are arranged inthe stacked mode, the number of partition walls needing to be arranged in the partition area is reduced while the packaging effect is guaranteed, and the screen-to-body ratio of the display substrateis increased.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display substrate. Background technique [0002] With the advancement of science and technology, digital display devices such as smartphones and tablet computers are widely used, and display screens are indispensable human communication interfaces in these display devices. Such as organic light emitting diode (Organic Light Emitting Diode, OLED) display panel has the advantages of self-illumination, energy saving and consumption reduction, bendable, good flexibility, etc., and the display device for realizing display does not require a backlight source, and has fast response and The feature of good display effect has attracted the attention of users and is widely used in terminal products such as smart phones and tablet computers. [0003] With the rapid development of electronic devices, users have higher and higher requirements for screen-to-body rati...

Problems solved by technology

In order to increase the screen occupancy rate, in the prior art, a laser is used to make a hole of a relatively large size on the display screen, which is suitable for the camera of a mobile phone, but water vapor easily invades the inside of the display screen through the hole and damages the display screen. A partition area is set around the opening to block water vapor, but the border width of the existing partition area is relatively large, which is not conducive to improving the screen ratio and aesthetics of the mobile terminal
