Abstract

<p>Original experimental and computational models for PSAs for flexible displays have been studied to clarify the property target for the PSA development. Possible defects in the devices, crack formation, delamination, and residual strain were addressed by a new theory, “Multiple-Neutral-Plane Phenomena”, with an originally developed software using Vector Finite Element Method. Peel adhesion values were found to be correlated with tan δ from DMA multiplied by tensile modulus from stress-strain curves, which offered a prediction equation for peel strength. The study has enabled a PSA material producer to develop PSAs for the application.</p>
