Abstract
An OLED display panel, a packaging method thereof, and an OLED display device are provided. The OLED display panel comprises a substrate and a cover plate opposite to the substrate. An OLED device is provided on the substrate. The cover plate is attached onto the substrate so that the OLED device is located between the substrate and the cover plate. A packaging structure is provided between the substrate and the cover plate. The packaging structure surrounds periphery of the OLED device to hermetically package the OLED device in a dry and anti-oxidation manner. The packaging structure provided in periphery of the OLED device between the substrate and the cover plate in the OLED display panel can not only absorb moisture and oxygen well, but also hermetically package the OLED device more tightly, thereby protecting the OLED display panel against erosion of moisture and oxygen and ensuring better hermetical packaging effects.
