P‐169: Study on the Behavior of Adhesive Cohesive Properties According to Cyclic Test of Foldable Products

In foldable display products, an adhesive is affected by the fatigue delamination force. F‐d curve and Gc value of dynamic and static test do not exhibit a significant difference, but microbubbles are observed in dynamic folding. In this study, the fatigue delamination of adhesive in real user scene...

Summary:In foldable display products, an adhesive is affected by the fatigue delamination force. F‐d curve and Gc value of dynamic and static test do not exhibit a significant difference, but microbubbles are observed in dynamic folding. In this study, the fatigue delamination of adhesive in real user scene is investigated and its measurement methodology is constructed.
