Abstract
The present invention provides a film packaging structure for an OLED, an OLED device, and a display apparatus. The film packaging structure for an OLED is an OLED film packaging structure, which includes a flexible film for packaging an OLED unit. The flexible film includes at least one layer of inorganic film, and at least one layer of organic film which is alternately stacked with the at least one layer of inorganic film. Each layer of organic film in the at least one layer of organic film is an integral film, and each layer of inorganic film in the at least one layer of inorganic film includes a plurality of non-connected inorganic film segments. The display apparatus includes the OLED device. The OLED film packaging structure, the OLED device and the display apparatus utilize inorganic films and organic films which are alternately stacked with the inorganic films.
