reliably under broader temperature ranges and harsher mechanical deformation compared to those for
foldable displays. As commercialization progresses and user feedback is gathered, these specifications will be
refined and improved. Additionally, global requirements for environmental sustainability must be
considered, necessitating active research into adhesives that can be degraded or reused in flexible displays.
