Claim:
1. A thin-film packaging method, comprising following steps: forming an Organic Light-Emitting-Diode (OLED) layer on a Thin-Film-Transistor (TFT) substrate; forming a first inorganic packaging layer on the OLED layer; forming a coupling agent unit on the first inorganic packaging layer; and forming an organic packaging layer on the coupling agent unit; wherein, the organic packaging layer includes a buffer sublayer and a resist sublayer sequentially formed on the coupling agent unit, the coupling agent unit generates chemical reacts with the first inorganic packaging layer and the buffer sublayer in order to increase an adhesive strength between the first inorganic packaging layer and the organic packaging layer; wherein, a chemical formula of a composition of the coupling agent unit is Y(CH)nX wherein, a chemical formula of the organic packaging layer is SiOxCyHz, a thickness of the organic packaging layer ranges from 1000 nm to 5000 nm; and wherein, the buffer sublayer is formed by depositing on the coupling agent unit through a plasma enhanced chemical vapor deposition (PECVD) method, a gas flow ratio of O2 to Hexamethyldisiloxane (HMDSO) for depositing the buffer sublayer is that O2:HMDSO<3:1, wherein, a radio frequency power of HMDSO ranges from 200 W to 800 W, a flow rate of HMDSO ranges from 10 sccm to 50 sccm, a radio frequency power of O
