Apple has submitted production line orders for its upcoming foldable iPhone, effectively confirming that the device will launch this year, claims a Chinese leaker.

According to the Weibo account "Fixed Focus Digital," assembly lines recently received the orders from Apple, which has apparently allowed the leaker to learn the crease measurements for the device's 7.8-inch inner display.

The crease depth is said to have been controlled to under 0.15 mm. Crease depth refers to how deep the groove or indentation at the fold is. A smaller number means the crease is shallower and less noticeable to the eye and to the touch.

The crease angle is said to be under 2.5 degrees. Crease angle describes how sharp the fold line appears when the display is unfolded, which is measured as the angle formed at the crease area. A smaller angle indicates a smoother, flatter transition across the fold, rather than a sharp ridge or valley.

Unfortunately, competing foldable brands don't publish such crease measurements, so it's not easy to compare the figures against anything on the market. However, Apple's foldable iPhone is expected to feature a new type of display panel developed by Samsung that has never been used in a foldable product, and which has been described variously as being "virtually crease free" and having "no crease at all."

Separately, Chinese site UDN last year reported that Apple had solved "the crease problem" that has plagued most foldable smartphones, and the foldable ‌iPhone‌ will be the first crease-free foldable on the market.

Reports suggest Apple's foldable iPhone will feature a 7.8-inch main display when unfolded and a 5.5-inch cover display. The device is expected to adopt a book-style design similar to Samsung's Galaxy Z Fold, rather than a clamshell form factor.

According to analyst Ming-Chi Kuo, Apple's first foldable will include two rear cameras, a single front-facing camera, a single selfie camera on the inner display, and Touch ID integrated into the power button. The device could measure just 4.5mm thick when unfolded, and between 9mm and 9.5mm when closed.

Apple is expected unveil the foldable alongside the iPhone 18 Pro models in September, representing the biggest form factor change since the original iPhone in 2007.
