iPhone Duo's Anti-Crease Nano-Texture Display Won't Be Proven Until Buyers Live With It
Apple's first foldable, the iPhone Duo, reaches stores next month with a matte nano-texture display meant to make its screen crease less visible, but brief hands-on looks cannot show how the fold line ages.
Apple announced the iPhone Duo earlier this month, and the reaction was immediate, since observers had been waiting to see how the company would address problems that have dogged rival foldables. Only brief hands-on sessions have been possible so far, because the phone does not reach stores until next month.
The crease is the central trade-off of the foldable category. With current technology, a flexible display that folds cannot avoid leaving a mark along the fold, and manufacturers have spent years reducing how obvious it is. Apple's answer is a matte nano-texture coating on top of the screen that cuts light reflection sharply. Some people who have seen the phone in person say the crease is barely noticeable; others say it remains visible and will only get worse with use. Engadget's own hands-on found the crease "easier to feel with your finger than observe with your eyes."
A faint crease at this stage proves little, because damage accumulates. Samsung's Galaxy Z Fold 8 ships unfolded, and its screen looks flat when it is first taken out of the box. The fold line becomes more noticeable as the phone is opened and closed, and photographs of foldables with damaged screens are easy to find online. Thousands of folds spread over months or years are what will test the nano-texture coating.
Multiple Apple executives have said publicly that they are proud of the iPhone Duo and that they expect it to be more durable than competing foldables. That claim cannot be checked until the phone reaches a mass of consumers, and it will take longer still to learn how well the screen resists years of use. The extreme durability experiments that YouTubers typically run are likely to provide the first real tests.
Reviews, including Engadget's, will arrive soon after launch, but they can describe only a phone fresh out of the box. Whether the screen looks the same after a few months of daily folding is a separate question, and one that no early impression can settle.
Apple does get credit for producing a screen whose crease already looks much less noticeable in the first days of use. Competitors are likely to move quickly to match it.
