Popis: As the next-generation flexible display elements are very vulnerable to moisture, securing proper encapsulation is a decisive factor in enabling a long working life. Therefore, together with the recent development of plastic barrier films with very low permeabilities, interest in the permeabilities of sealants used for perimetric sealing has been increasing. In this study, equipment with a resolution of approximately ∼10−7 g·day−1 to measure moisture permeability in perimetric sealing was established, and the permeabilities of different sealants were measured. This equipment could have applications not only in the display industry but also in other sectors requiring encapsulation technology, such as the semiconductor and solar cell industries.
