Abstract

The present invention discloses a composite film, a manufacturing method thereof and an encapsulation structure comprising the composite film. The composite film comprises at least one matrix membrane, each of which comprises at least one waterproof film. In the technical solutions provided by the present invention, the composite film comprises a matrix membrane comprising at least one waterproof film, and therefore, the composite film can be directly disposed on an OLED when the OLED is encapsulated by using the composite film. Accordingly, during an encapsulation process, the used process is simple, the process steps become less, the process time is short, and the required equipment is simpler, so that the production cost is reduced, and the production efficiency is improved.
