On the 10th of this month, Apple officially launched its first foldable iPhone, the iPhone Duo, with a starting price of 15,999 yuan.
What's drawing attention this time is not just the foldable screen itself, but also the iconic open-close perspective folding animation of the iPhone Duo, which many netizens call "Apple's exclusive black technology."
As the phone opens and closes, the iPhone Duo's screen gradually blurs and darkens, creating a visual effect of "perspective and seamless transition."
Tech blogger Digital Chat Station revealed that Chinese brands will soon port this animation effect to their own foldable products, so we should see it very soon.
Notably, independent developers have already replicated Apple's animation effect. From Android phones to Mac computers, replicated versions for various platforms have emerged one after another, suggesting that the technical barrier is far lower than imagined.
A netizen shared their adaptation results on social media. They perfectly ported Apple's animation to the Samsung Galaxy Z Fold8, with effects comparable to the iPhone Duo.
Industry insiders state that the technical barrier for the iPhone Duo's open-close perspective animation is not high; the core principle involves using hinge angle data to adjust the screen shader's perspective parameters in real time.
In terms of hardware configuration, the iPhone Duo features a 7.6-inch inner screen and a 5.4-inch outer screen, powered by the A20 Pro chip, with a 48MP main camera and a 48MP ultra-wide-angle lens, and supports side-mounted fingerprint recognition.
This is the largest iPhone in Apple's history, a full 50% bigger than the iPhone 18 Pro Max; the outer screen display area is over 90% of the iPhone 18 Pro's. Furthermore, Apple's iOS system has been completely revamped, bringing various new features.
Additionally, the device's frame and hinge cover are made of Grade 5 titanium, the inner screen has an anti-scratch coating, the front and back are protected by Ceramic Shield panels, and it supports IP68 water and dust resistance.
