MEASUREMENT OF ULTRA-LOW MOISTURE PERMEATION THROUGH EPOXY SEALING IN OLED ENCAPSULATION
Byung Il Choi, Sang Bong Woo, Jong Chul Kim
Abstract:
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 film with very low permeability, interest in the permeability of sealant used for periment sealing has been increasing. In this study, the equipment to measure moisture permeability in periment sealing was established, and the permeability of different sealants was measured, whose resolution was approximately ~10-7 g·day-1.
