A series of adhesion strength modified layer (ML) was introduced to develop the new TFE structures. The new encapsulation structures provided the long‐life time performance for the flexible OLED device. No pixel shrinkage or dark spots appeared after storing in an environment of 85% humidity and at 85 °C over 20,000 hours. The adhesion strength of the thin film system improved and the risk of peeling decreased.
