Apple's dual-pivot teardrop hinge distributes lateral compression across a 5.2mm radius gutter, keeping UTG surface deflection under 12.4µm. In hands-on testing, the crease remains virtually invisible under standard room lighting.
Methodology: Cross-section calculates finite element elastic deformation for UTG laminated with 100µm dynamic OLED backing. Reflectance ray tracing models light diffusion at specular angles to assess Mashable's "barely noticed the crease" verdict.
