Problems solved by technology

[0004] Although the above encapsulation structure plays a certain role in encapsulation, since the edge of the metal layer is a straight line, the contact position between the inorganic encapsulation layer and the metal layer is a linear structure, and the growth of the inorganic encapsulation layer on the edge of the metal layer presents a single pattern. When the metal layer When a gap is formed between the straight edge of the metal layer and the inorganic packaging layer, external water and oxygen can easily penetrate into the display area along the straight edge of the metal layer, thereby affecting the normal use of the display panel and even causing device failure. Poor encapsulation

Abstract

The invention provides a packaging structure, a display panel, a display device and a manufacturing method thereof. In the packaging structure provided by the present invention, based on the arrangement of multiple metal trims and multiple insulating grooves, the inorganic packaging layer presents a variety of arrangement characteristics when growing on the edge of the metal layer, which breaks the growth of the inorganic packaging layer in the prior art. Since the setting of metal trim and insulating groove increases the resistance of water and oxygen intrusion and the length of the intrusion path, it can effectively block the intrusion of water and oxygen from the outside to the display panel, improve the packaging effect of the display panel, and extend the lifetime of the display panel. service life.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging structure, a display panel, a display device and a manufacturing method thereof. Background technique [0002] The flexible display panel is a light and thin self-luminous display panel, which not only has a good display effect, but also can be bent to meet the requirements of the actual use environment. [0003] Existing flexible display panels generally include a flexible display substrate and an encapsulation structure layer arranged on the surface of the flexible display substrate. Specifically, the encapsulation structure includes an insulating layer formed on the flexible display panel, and an insulating layer formed on the surface of the insulating layer away from the flexible display panel. The metal layer, the inorganic encapsulation layer formed on the surface of the metal layer away from the insulating layer, the inorganic encapsulation layer realizes the ...
