68‐4: A New Thin‐Film Encapsulation Structure for Flexible OLED Display with Long Lifetime

Abstract

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.

P‐78: An Adhesion Reinforced Structure for TFE of Flexible OLED Display

“…In our previous study 6 , a series of modified layers (ML)was introduced to improve the adhesion performance of thin film encapsulation (TFE) layers. Modified layers played important roles in balancing the adhesion strength were produced by PECVD or PEALD.…”

“…How to improve the mechanical performance and the durability of the flexible OLED device was attracts the attention of researchers [4][5] , especially the improvement related to the EL materials and the interface between EL materials and encapsulation structures. Interlayers were used in a prior work 6 to increase the adherence of EL materials to thin film encapsulation (TFE) layers.…”

“…These factors collectively contribute to the overall mechanical response of the thin film. [3,4] Furthermore, the interfacial bonding energy between the thin film and its substrate also plays a role in the wrinkling phenomenon. The strength of the bond between the film and substrate can influence the initiation and propagation of wrinkles on the film's surface.…”
