“The iPhone Duo’s foldable display may be free from visible creases, but the area above the hinge is surprisingly soft and can develop wrinkles when pressed.”
Interestingly, Kang’s observations are consistent across multiple iPhone Duo units, suggesting this is not an isolated issue. The behavior could be linked to the rumored use of variable-thickness ultra-thin glass (UTG) by Apple. This design involves a thinner glass layer over the hinge, allowing flexibility, while thicker glass elsewhere provides added durability. This approach, if true, marks a significant departure from traditional foldable display designs and showcases Apple’s innovative strategy in addressing the mechanical stresses of foldable screens.
Ice Universe speculates that Apple’s adoption of variable-thickness glass could be inspired by Corning’s Variable Thickness Glass (VtG), introduced a few years ago. This technology offers a balance between easy bending and increased robustness, thanks to its design that combines a thin central region with thicker surrounding areas. Corning’s press release on VtG highlights its potential to enhance both bendability and durability compared to uniform glass thickness.
“Apple’s rumored use of variable-thickness glass could represent a radical new approach to foldable display engineering, potentially offering a blend of flexibility and durability.”
Despite these insights, Apple has not confirmed if the iPhone Duo employs VtG technology. The lack of official confirmation leaves room for speculation, but the evidence suggests a sophisticated engineering solution aimed at optimizing the foldable design. As foldable technology evolves, Apple’s approach could set a new benchmark for balancing aesthetics and functionality in future devices.
