Abstract
The present invention relates to a thin-film package for an organic light-emitting diode, an organic light-emitting diode using the thin-film package, and an organic light-emitting display. The thin-film package includes at least one inorganic film layer and at least one organic film layer, the inorganic film layer and the organic film layer being alternately stacked; the inorganic film layer is made of a material selected from any one of poly(silicon nitride), poly(silicon oxide), poly(silicon carbonitride), poly(silicon carbooxide), poly(silicon carbonitride) and poly(silicon carbonitrideoxide), or any combination thereof; and the organic film layer is made of a material selected from any one of acrolein-based polymer, silicon-based polymer and epoxy-based polymer, or any combination thereof. Compared with a traditional thin-film package structure, the thin-film package according to the present invention achieves a better water and oxygen resistant effect, suffers from a lower stress, and is thus suitable for use in a flexible OLED.
