Preventing hydrogen and water vapor from permeating through encapsulation layer plays an important role in TFT Reliability. To improve a blocking characteristic, encapsulation inorganic layers were studied. A SiNx and SiO2 multilayered inorganic deposition method for OLED has been developed to obtain a reliable performance.
