1. An encapsulation structure of an organic electroluminescent device, comprising:
- a substrate;
an organic electroluminescent device located on the substrate; and
at least one film encapsulation layer covering the organic electroluminescent device, wherein the film encapsulation layer consists of an inorganic film, a fluorocarbon polymer film, and an organic polymer film disposed between the inorganic film and the fluorocarbon polymer film,wherein the organic electroluminescent device is covered with from 1 to 20 layers of the film encapsulation layer, andwherein the encapsulation structure excludes a pressure sensitive adhesive layer except for the 1 to 20 layers of the film encapsulation layer,wherein the material of the organic polymer film is selected from one or combinations of PET (polyethylene terephthalate), PEN (polyethylene naphthalate), PC (polycarbonate), PI (polyimide), PVC (Polyvinyl chloride), PS (polystyrene), PMMA (polymethylmethacrylate), PBT (polybutylene terephthalate), PSO (polysulfone), PES (poly(p-phenylenediethyl)sulfone), PE (polyethylene), PP (polypropylene), silicone (polysiloxane), PA (polyamide), PVDF (poly(vinylidene fluoride)), EVA (ethylene-vinyl acetate copolymer), EVAL (Ethylene-vinyl alcohol copolymer), PAN (polyacrylonitrile), PVAc (poly(vinyl acetate)), Parylene (poly(p-xylene)), Polyurea, PTFE (polytetrafluoroethylene) and epoxy resin.

Abstract
Disclosed are encapsulation structures, encapsulation methods and display devices of organic electroluminescent devices. The encapsulation structure comprises: a substrate (3); an organic electroluminescent device (2) located on the substrate (3); and at least one film encapsulation layer (1) covering the organic electroluminescent device (2), wherein the film encapsulation layer (1) comprises an inorganic film (11) and a fluorocarbon polymer film (13). The encapsulation structure can effectively improve the film encapsulation layer (1)'"'"'s ability to block water and oxygen so as to effectively extend the lifetime of OLED devices.
