The iPhone Duo Has a Crease: Apple’s Clever Fix Makes It Harder to See

Apple's newly announced iPhone Duo features a 7.6-inch inner display with a visible crease, but the company has implemented several design features to make the line less noticeable. The inner display uses a nano-texture finish to reduce glare and minimize crease visibility. The precision hinge supports the center of the display when fully opened, helping to prevent stress on the screen as it folds.

Additionally, the display construction includes high-strength glass, a titanium plate, custom adhesives, and a polymer cover layer to allow for smooth movement during folding. While the crease remains present, Apple's design choices make it less obvious during normal use. However, long-term durability and performance have yet to be independently tested, as the iPhone Duo is set to launch on Oct.

23 for $1,999. Competing with Samsung's advanced foldable phones, Apple's Duo relies on both its display engineering and software capabilities, such as a reimagined iOS 27 experience designed for the foldable screen. The software allows for adaptive interfaces, side-by-side app usage, and content shifting across the larger display.

Buyers should consider whether the enhanced display, despite the crease, offers enough utility to justify the premium price, especially for those who frequently multitask or work across multiple apps.
