The iPhone 15 might have a foldable screen

A new report claims Apple is on track to deliver its first foldable phone in 2023.

While we're still waiting to see just how small the notch on the iPhone 13 will be, often-accurate analyst Ming-Chi Kuo is looking a little further down the road. In a new report, Kuo predicts that Apple will launch a foldable iPhone in 2023.

A folding iPhone has been rumoured before, but Kuo's claims are a bit stronger here. He claims that Apple is already shoring up suppliers for the parts and is looking to ship the must-have device in big numbers:

We forecast that Apple will likely launch a foldable ‌iPhone‌ with an 8-inch QHD+ flexible OLED display in 2023, with SDC as the exclusive display supplier and Samsung Foundry as the exclusive DDI foundry provider. Based on Apple's requested capacity plan, we predict that the foldable ‌iPhone‌ shipments will reach 15-20 million units in 2023. We expect that the foldable ‌iPhone‌ will adopt TPK's silver nanowire touch solution because of its several advantages over SDC's Y-Octa technology.

An 8-inch screen would make the folding iPhone bigger than the iPad mini (7.9 inches) and Samsung's Galaxy Z Fold 2 (7.6 inches).

Kuo says Apple will be using silver nanowire for the touch interface, which will give the company a long-term competitive advantage over Samsung's current Y-OCTA (Youm On-Cell Touch AMOLED) tech. Future foldable devices will require touch technology that supports multiple folds (vs. only a single fold in current foldable smartphones), rollable, medium to large size display, and durability, Kuo writes. When comparing the advantages of the above specifications, the silver nanowire is similar or superior to SDC's Y-Octa.

Apple has been experimenting with silver nanowire for years in iPads and Apple Watches, with the display tech most recently making its way into the HomePod and HomePod mini, Kuo says. Durability was an issue with the first round of folding phones, with Samsung delaying the launch of its Galaxy Fold in 2019 to deal with numerous engineering issues.

It was previously rumoured that Apple was testing two different folding iPhone prototypes, with one having a dual-screen design and the other opening vertically like a flip phone. That report claimed Apple's biggest sticking point was the hinge, which Kuo doesn't mention in his analysis.
