Apple today announced the “iPhone Duo,” a new kind of iPhone featuring two screens and a foldable inner display.
The two halves of the iPhone Duo connect into a single continuous frame with the same aspect ratio across both displays, and Apple said the transition between open and closed is designed to feel fluid. When fully open, Apple called it the thinnest iPhone ever made, with an architecture that packages its components into the camera plateau.
A custom hinge, made from more than 100 tiny precision components, holds the display flat when open and controls the folding motion. Apple said the structure uses a multi layer lamination design with viscoelastic adhesives that let the display’s layers glide against each other during folding “like pages in a book,” preventing distortion over time. A titanium plate forms the bottom layer for added durability, with carbon fiber support plates creating a stiff, lightweight base for the display to rest on.
For the display surface itself, Apple said it created a custom nano texture finish that cuts down on glare and reflections. The company also described a separate micro lens texture, produced using maskless laser lithography that writes each lens pixel by pixel, which it said creates a “perceptually flat matte surface” that minimizes the visibility of the fold crease while still feeling premium to the touch.
The inner display measures 7.6 inches, which Apple said is 50% larger than the iPhone 18 Pro Max and 80% larger than the iPhone 18 Pro, while the outer display is 5.4 inches and offers 90% of the screen area of the iPhone 18 Pro. Apple Pencil support is coming to both displays later this year.
The frame is machined and polished titanium, with Ceramic Shield on the back and Ceramic Shield 2 on the front, and the device carries an IP68 rating. iPhone Duo comes in two colors, Star White and Night Sky. Touch ID is built into the side button, and the device can also be unlocked using Apple Watch.
