An OLED packaging method and structure are disclosed. In the present invention, forming a ring-shaped organic layer on the edge of the inorganic barrier layer, and then forming a planar organic layer on the upper surface of the inorganic barrier layer surrounded by the ring-shaped organic layer. The planar organic layer and the ring-shaped organic layer are integrated together to form an organic buffering layer. The upper surface of the organic buffering layer is flat, and the region of the organic buffering layer corresponding to the edge position of the inorganic barrier layer does not have an upward projection, the film thickness and morphology of the inorganic barrier layer are not affected. The present invention can improve the barrier effect of inorganic barrier layer for water and oxygen. The upper surface of the organic buffering layer in the OLED packaging structure is flat and has a good encapsulation effect.
