We developed a high-performance encapsulation layer for the fabrication of high-resolution OLEDs with UTE(Ultra-Thin-Encapsulation) structure. The UTE structure was achieved by sequential deposition of organic/inorganic layers by iCVD(initiated Chemical Vapor Deposition) and PEALD(Plasma Enhanced Atomic Layer Deposition) processes in a one-chamber system capable of depositing iCVD and PEALD layers. The basic thin film characteristics were investigated systematically. Especially, cross-section analysis clearly illustrated the excellent conformal coverage...
