Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0039] In one embodiment, refer to figure 1 , providing a display screen, including a base film layer 100 , a dam 200 and an encapsulation film layer 300 . The display screen has a display area AA and a non-display area NAA. There is a light-emitting device D in the display area AA, thereby performing effective light-emitting display. The non-display area NAA is a frame area.

[0040] The base film layer 100 is a base for forming an upper layer dam 200 . The dam 200 is formed on the base film layer 100 and located in the non-display area. Furthermore, the embankment 2...

Abstract

The application relates to a display screen and a making method of the display screen. The display screen has a display area and a non-display area. The display screen includes a base film layer, a dam and a package film layer. The dam is formed on the base film layer and located in the non-display area, and includes a connection part and a partition part connected with each other, wherein the connection part is connected with the base film layer, and the partition part is suspended. The package film layer includes an organic layer and an inorganic layer stacked together, and the inorganic layer extends from the display area to the non-display area to cover the organic layer and crosses the partition part. In the processing process of the display screen of the application, even if the distance between the cutting line and the opening edge of a mask forming the inorganic layer is short, the crack of the inorganic layer caused by the cutting heat / stress generated in the cutting process will be partitioned by the partition part and will not extend from the non-display area to the display area because the inorganic layer is partitioned by the partition part. Therefore, the package effect is ensured, and the display screen can have a narrow bezel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display screen and a manufacturing method of the display screen. Background technique [0002] The display screen includes an encapsulation film layer, and has a display area and a non-display area. Wherein, the non-display area is a frame area. The encapsulation film layer usually includes an inorganic layer and an organic layer, thereby blocking water and oxygen and preventing water and oxygen from entering the light-emitting layer of the display screen. The inorganic layer and the organic layer are stacked, and the inorganic layer extends to the non-display area, and then wraps the organic layer. [0003] In the production process of display screens, usually multiple display screens are processed at the same time, and then formed into independent display screens by laser cutting. The cutting line of the laser cutting is the edge of the display. If the distance...
