Abstract
A packaging method of electro-luminescence devices. By controlling the moisture and oxygen in an environment, a glass substrate with electro-luminescence devices and a glass covering plate corresponding thereto are provided. A frame glues with an opening is applied on each frame on the glass plate that corresponds to each electro-luminescence device on the substrate. The glass plate is laminated with the glass substrate via the frame glues. The glass substrate is cut into individual package including an electro-luminescence device enclosed by a part of the glass substrate, a part of the glass plate and the frame glue except that a side thereof is exposed to the environment via the opening. Each of the packages is disposed in a vacuum cavity with the opening facing the packaging material in a glue tub in the vacuum cavity. The pressure of the vacuum is raised up to a certain value to have the packaging material filling the cavity containing the electro-luminescence in the package. The packaging material is then cured.
