Display substrate, manufacturing method thereof, and display device

Abstract

A display substrate, a preparation method thereof, and a display device. The display substrate has a display area and a frame area around the display area, including a base, a pixel unit, at least one barrier dam and a first encapsulation layer. The pixel unit is located on the base corresponding to the position of the display area; at least one barrier dam is located on the base corresponding to the position of the frame area, at least one of the barrier dams is on a side away from the base At least one groove is provided on the side, the depth direction of the groove is perpendicular to the base, the extension direction is the same as the extension direction of the barrier dam provided with the concave groove, and the groove is far away from the base one side is open; and a first encapsulation layer covers the barrier dam, a portion of the first encapsulation layer over the groove conforming to the groove. The groove can improve the packaging effect of the display substrate.

Description

technical field [0001] At least one embodiment of the present disclosure relates to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the popularity of electronic display products, how to improve the adaptability of electronic display products to the environment has attracted more and more attention from users. For example, during the production and use of electronic display products, water vapor and oxygen in the external environment will invade the interior of electronic display products. For example, water vapor and oxygen can react with the internal structure of electronic display products and affect their electrical properties. Reduce the performance and life of electronic display products. However, in view of the above problems, although various packaging technologies have been developed by various manufacturers, the current packaging technologies cannot meet the further demands of customers on the packaging ...

Problems solved by technology

For example, during the production and use of electronic display products, water vapor and oxygen in the external environment will invade the interior of electronic display products. For example, water vapor and oxygen can react with the internal structure of electronic display products and affect their electrical properties. Reduce the performance and lifespan of electronic display products

However, in response to the above problems, although various packaging technologies have been developed by various manufacturers, the current packaging technology cannot meet the further needs of customers for the packaging effect of electronic display products.
