There have been reports that Xiaomi purchased a large number of UTG (ultra-thin glass) displays. It also seems to confirm the rumors that Xiaomi is developing a new foldable smartphone. Recently, a brand-new Xiaomi foldable screen smartphone patent has been exposed. It shows some design elements of a (possible) upcoming handset. Particularly, it shows what front and rear camera layout it will come with.
Ultra-thin flexible glass (UTG) can be said to be the optimized version of the polyimide (CPI) film used in the first generation of folding phones (Samsung GALAXY Fold / Huawei Mate X). And its durability is relatively stronger, while it is thinner. It adopts a strengthening process to enhance the flexibility and durability of 30μm (1μm=1/1000000m) ultra-thin glass. During the process, special materials are injected into the ultra-thin glass to ensure its uniform flexibility. In short, ultra-thin flexible glass has a wide range of application scenarios on screens such as folding screens and surround screens.
As we understand the patent shows that when the phone is folded, the cameras 13, 14, and 15 are all facing the user. In other words, we will get a set of front camera systems consisting of three cameras. When the camera 13 is facing away from the user, the latter can also use one or more of the camera 13, the camera 14, and the camera 15 to capture a photo. The camera 15 can also be used as a rear camera. It can assist in enhancing the device’s rear camera function.
However, the current related design is still only a patent, which means that Xiaomi may not resort to it.
