Abstract

A packaging method for a display panel, a display panel and a display device. The packaging method of the display panel comprises: forming at least one thin film encapsulation inorganic material layer on the thin film encapsulation area of ​​the display substrate; making a photoresist pattern on the thin film encapsulation inorganic material layer; using the photoresist pattern as a mask to encapsulate the thin film The inorganic material layer is etched to form a thin film encapsulation inorganic layer including the first opening pattern. The packaging method of the display panel uses a photoresist mask instead of a chemical vapor deposition (CVD) mask, thereby avoiding problems such as inaccurate coating areas caused by deformation of the CVD mask due to continuous use for a long time.

Description

technical field [0001] At least one embodiment of the present disclosure relates to a packaging method of a display panel, a display panel and a display device. Background technique [0002] Organic light-emitting diode display devices are very sensitive to water vapor and oxygen, and the water vapor and oxygen that penetrate into the device are the main factors affecting the life of the device. Therefore, thin film encapsulation (Thin Film Encapsulation, TFE) is very important for organic light-emitting diode devices. At present, the common TFE packaging structure is: inorganic material + organic material + inorganic material film layer structure, and the electroluminescent material is encapsulated inside the device to achieve the purpose of blocking water and oxygen, thereby providing protection for the electroluminescent material. In the packaging process, the chemical vapor deposition process (CVD) is generally used to make the inorganic layer. When the inorganic layer c...
