Abstract:
A packaging method of electro-luminescence devices, comprising:providing a glass substrate comprising a plurality of electro-luminescence devices and a glass plate in an environment with a moisture concentration and an oxygen concentration under control; coating a frame glue on each position on the glass plate corresponding to each electro-luminescence device on the glass substrate in the environment, wherein each frame glue comprises an opening; laminating the glass plate with the glass substrate in the environment to have each electro-luminescence device enclosed by the corresponding frame glue except that one side of each electro-luminescence device without having a circuit is exposed to the environment via the opening; curing the frame glue in the environment; cutting the glass substrate into a plurality of individual packages in the environment, each of the package comprising one of the electro-luminescence devices in a cavity enclosed by one part of the glass plate, one part of the substrate and one of the frame glues except from the openings; disposing the packages into a vacuum cavity having a glue tub, the glue tub comprising a packaging material and the openings of packages facing the packaging material without being in contact with; pumping air from the vacuum cavity to vacuum the packages and the packaging material; immersing the openings into the packaging when a pressure of the vacuum cavity reaches a certain value, so that the packaging material is injected to fill the cavity; and curing the packaging material in each of the packages.
