Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate, a light-emitting function layer arranged on the substrate, a thin film packaging layer arranged on the substrate and the light-emitting function layer and covering the light-emitting function layer, a drying layer located on the substrate and arranged around the thin film packaginglayer, a packaging cover plate arranged on the drying layer and the thin film packaging layer, and a curing adhesive layer for fixing the substrate and the packaging cover plate. An annular groove surrounding the drying layer is formed between the drying layer and the curing adhesive layer, and a packaging adhesive layer is arranged in the annular groove. By means of the structural form of the packaging cover plate and the glass cement, at the same time, by combining the thin film packaging layer, the drying layer and the curing adhesive layer, the mixed packaging of the light-emitting functional layer is achieved, the good water-oxygen barrier property can be guaranteed, and the good packaging strength is achieved. In addition, through the manufacturing method of forming the packaging adhesive layer between the drying layer and the curing adhesive layer, the size of a channel through which the water vapor enters the display panel can be effectively controlled, and the method can adaptto the packaging of OLED display panels of different sizes.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Display (OLED) is a new generation of display, which has many advantages such as self-illumination, fast response, wide viewing angle and saturated color compared with liquid crystal display. However, OLED devices are sensitive to water and oxygen in the air and are easy to absorb water and oxidize, causing OLED device life to decline or pixel failure. Therefore, effective packaging of OLED devices to fully isolate OLED devices from water and oxygen is crucial to prolonging the service life of OLED devices. important. With the development of OLED display technology, the current single OLED packaging structure can no longer meet the multiple needs of OLED devices for water and oxygen barrier and packaging structure strength. Contents of the invention [000...
