Problems solved by technology

However, this solution results in a thinner film encapsulation layer at the sidewall of the groove, which is less effective in blocking water vapor and oxygen, and cannot effectively block water vapor and oxygen from entering the display area through the sidewall of the groove, which affects the service life of the display panel.

Embodiment Construction

[0063] In the display panel, the display panel includes a display area and a non-display area. In order to increase the screen ratio of the display panel, a first groove is usually provided in the non-display area of ​​the display panel. The first groove may be a blind hole for installing functional components such as a camera module, thereby helping to reduce the overall thickness of the stacking area of ​​the camera module and the display panel. In the manufacturing process of the display panel, one solution is to first set the first groove in the non-display area, and then perform the packaging process. However, such a solution will cause the thin film encapsulation layer formed on the sidewall of the first groove to be thinner, the effect of blocking water vapor and oxygen is poor, and it cannot effectively prevent water vapor and oxygen from entering the display through the sidewall of the first groove. area and affect the service life of the display panel.

Abstract

The embodiment of the invention provides a display panel, a manufacturing method thereof and a display device. The display panel relates to the technical field of display and is used for solving the technical problem that water vapor and oxygen enter a display area through the side wall of a first groove, and the service life of the display panel is affected. The display panel comprises a display area and a non-display area. The display panel further comprises a substrate, wherein a first groove is formed in the non-display area of the substrate; the light-emitting unit is arranged in the display area, and the light-emitting unit is arranged on the substrate; the first blocking dam is arranged in the non-display area, and at least part of the first blocking dam is arranged in the first groove; and the thin film packaging layer is arranged on the surfaces of the light-emitting unit and the first blocking dam.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel, a method for manufacturing the same, and a display device. Background technique [0002] An organic light emitting diode (Organic Light Emitting Diode, OLED) display panel is a display device that realizes display by utilizing the self-luminous principle of organic electroluminescent materials. Compared with liquid crystal display devices, organic light-emitting diode display panels have many advantages such as self-luminescence, fast response speed, low-voltage driving, high brightness, and lightness, and thus gradually become the mainstream in the display field. [0003] In order to increase the screen ratio of the display panel, a groove is usually provided in the non-display area of ​​the display panel for installing functional components such as a camera module. At present, one solution for disposing grooves on the display panel is to first ...
