Apple releases new versions of iPhones every year, topping themselves each time with the innovations introduced in the newer models. OLED displays are capable of being shaped into curves or even folded, unlike LCD screens, which were used in older iPhones.
Touchless gestures are also apparently on their way to an iPhone near you, and they could be implemented in two years at the earliest.
Both this and the curved screens are now in the early research and development phase at Apple, and thus it's not a given that either or both of them will actually make it to shipping products. The only one that has a slight curvature is the iPhone X.
The person added that the capability would take into account the proximity of the user's finger to the screen. Those are two big features that were missing from the HomePod at launch, but which Apple promised to make available via software updates as soon as possible.
Apple has a number of new features in the pipeline for its upcoming iPhones. For example, the Moto Actions feature enables users to turn the lock screen on and off by waving a hand, among other things. Samsung is already working on a foldable smartphone, while Huawei is seeing increased success in Asia. Google's ATAP research group has been working on similar technology through a program known as Project Soli. It's also the first iPhone to feature an OLED display. The gestures wouldn't need to be close to the screen like how Apple is developing its gesture feature.
For the forthcoming iPhone generation, Apple is reportedly releasing three sizes, with the largest to top the iPhone 8 Plus' 5.5-inch screen, with about a 6.5-inch screen.
Trust Apple to be different.
