An OLED packaging method is provided, in which a first outer bound confinement layer is first formed and then, a first organic layer is formed on the first inorganic layer in an area enclosed by the first outer bound confinement layer so that facilities for forming the first organic layer can be diversified and an organic material used to form the first organic layer is not subjected to constraint in respect of viscosity thereof, whereby using an organic material with a reduced viscosity allows for better homogeneity of the first organic layer, the thickness reduced, and thus helping reduce a curving radius of the OLED package structure to realize rollable displaying with a reduced curving radius. Further, the first outer bound confinement layer helps block external moisture and oxygen from corroding the first organic layer in a sideway direction.
