Xiaomi has officially introduced its first quad-curved waterfall screen concept smartphone. The hyper quad-curved screen design of 88 ° enables visual interfaces to flow like water over the surface of the phone. The screen covers almost the entire frame of the smartphone, while its body does not carry ports or buttons, bringing forward the futuristic no-port unibody design.
Xiaomi engineers tried to make the smartphone as simple as possible and bring the “just a screen” form factor a step closer to life by pushing the limits of the classic smartphone form factor.
The 88° ultra quad-curved glass has virtually broken through the glass production technological limits. The difficulty of hot bending increases exponentially compared with ordinary curved glass. Self-developed glass processing equipment, hot bending under 800 °C high temperature and pressure, four different polishing tools and up to more than ten complex polishing procedures are required for polishing a part of such hyper-curved glass with a deep 88 ° bend on four sides. More importantly, thousands of attempts are behind such a piece of glass.
An innovative screen stacking design was adopted through breakthrough 3D bonding process in order to attach such a piece of 88 ° quad-curved glass to a flexible display. All of this guarantees perfect and flawless screen quality.
A key factor in determining the future shape of the smartphone is the shape of the display. New possibilities are forged with Xiaomi’s new breakthroughs in quad-curved waterfall screens, and crucial strides are made toward the target of a truly port-free unibody smartphone.
This innovative design means that the display can cover almost all sides of the phone. Physical ports and buttons may have their functions replicated by more elegant alternatives, thanks to 46 self-developed proprietary technologies. Groundbreaking innovations and engineering solutions are seamlessly incorporated, forming a visionary yet intuitive device, including ultra-thin piezoelectric ceramics, industry-first versatile film display acoustic technology, third-generation under-display cameras, wireless charging, eSIM processors, pressure-sensitive touch sensors, and more.
