Xiaomi officially announced the first quad-curved waterfall screen concept phone. Judging from the promotional video, the machine’s screen not only uses a waterfall screen design on both sides, but also uses a waterfall screen-like arc at the top and bottom.
According to the official introduction, this quad-curved waterfall screen concept phone adopts an 88-degree ultra-curved screen design on all sides. This means that the frame around the machine is almost replaced by the screen. In addition, the machine’s body has no holes or buttons, showing a non-hole design.
It should be noted that this is a concept product. Thus, this phone will not be mass-produced for the time being, and consumers will not be able to buy it. It is more to show the smartphone manufacturers’ exploration of future smartphone forms.
Anyways, we are familiar with waterfall screens. Last year, the VIVO NEX 3 and the Huawei Mate 30 Pro adopted similar designs. And Xiaomi’s concept machine not only uses 88-degree curved surfaces on both sides of the screen, but also 88-degree curved surfaces on top and bottom. To achieve this, it not only needs a bendable flexible screen but also a quad-curved glass and corresponding glass technology.
How Did Xiaomi Make A Quad-Curved Waterfall Screen Phone?
According to the official introduction, Xiaomi uses its self-developed glass processing equipment to form a single piece by hot bending at 800 degrees high temperature and high pressure. It uses four different polishing equipment and more than ten complex polishing processes to create a four-sided 88-degree deep bend super curved glass. In addition, it adopts an innovative screen stacking design to overcome the bending stress caused by the bending angle and the extremely small bending radius.
Another highlight of the machine is the integrated non-porous design. Xiaomi believes that “the shape of future smartphones depends on the shape of the screen.” As a result, it used the quad-curved waterfall screen to replace the middle frame of the phone. So the physical buttons and openings disappeared.

In order to achieve this goal, Xiaomi applied for 46 independent research and development patents. The new machine uses ultra-thin piezoelectric ceramics to achieve external sound emission. And the flexible film screen sound technology replaces the earpiece. Also, there are technologies such as high-power wireless charging, pressure-sensitive buttons, and third-generation under-screen lenses to solve the problem of opening holes for charging and taking pictures.
