Problems solved by technology

[0003] In order to increase the screen occupancy rate, in the prior art, lasers are used to punch 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 from the hole and damages the display screen. Partitions are formed by etching to cut off water vapor. When the existing partitions are formed with complex processes, many processes and high production costs

Abstract

The invention discloses a display substrate and a preparation method thereof, the display substrate is provided with a hole area, a partition area and a display area, the partition area at least partially surrounds the hole area, the partition area is arranged between the hole area and the display area, and the display substrate comprises an array substrate, a device layer arranged on one side of the array substrate in the display area and comprising an anode layer, partition parts arranged on one side of the array substrate of the partition area at intervals and comprising anode material layers having the materials the same as that of the anode layer, and sunken parts arranged between the partition parts and on the array substrate between the partition parts and the device layer. The anode layer of the device layer is used for achieving the normal display function of the display substrate, the anode material layer of each partition part is used for preventing water vapor entering the hole area from the outside from invading the display area, the anode layer and the anode material layer of the display substrate provided by the embodiment of the invention can be formed together by adopting the same process, and the process is simple. And the production cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display substrate and a preparation method of the 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] In order to increase the screen occupancy rate, in the prior art,...
