ENCAPSULATING METHOD OF ORGANIC ELECTRO LUMINESCENCE DEVICE

摘要

PURPOSE: An encapsulating method of an organic electro luminescence device is provided to avoid penetration of external humidity and increase life time of a product. CONSTITUTION: An organic electro luminescence device is encapsulated by forming(S10) a desiccant agent thin film on a thin sealing substrate. The sealing substrate is made of 0.5, 0.7, 1.1 mm glass or 0.3-1.1 mm plastic. The thickness of the desiccant agent thin film is 0.1-100 μm. Sealing material is formed(S20) at the boundary of the sealing substrate having the desiccant agent to form space for inert gas(N2). A luminescence substrate having a luminescence layer is assembled(S30) with the sealing substrate having the sealing material. Heat or ultraviolet ray is applied(S40) to harden the sealing material so as to attach the sealing substrate with the luminescence substrate.
