Figure 5. (A) The changes of max strain based on OCA thickness (blue shadow, left) and the shielding effect of rigid layer (right). The more distant layers are less affected by 1st adhesive thickness^[122]. Reproduced with permission. Copyright © 2019 Elsevier B.V.; (B) The max stress distribution based on folding shape. The Ω-shape is favorable for reducing folding radius^[123]. Reproduced with permission.
