As a follow-up to the insane wraparound display that was showcased with the Mi MIX Alpha, Xiaomi is back with another new concept with the Quad-Curved Waterfall Display. Like the Mi MIX Alpha, the Quad-Curve Waterfall Display concept has no ports or buttons a la vivo Apex 2019.
With this concept, the phone’s display curves by 88 degrees in all four sides, letting the visual UI flow throughout the screen like water. While it may sound similar to Huawei’s implementation with the P40 Pro and Pro+, Xiaomi’s implementation is more aggessive as it ditches buttons and ports in order to make the “just a screen” form factor a reality and to make the smartphone as simple as possible.
Creating a quad-curved display with an 88-degree curve angle is a feat by itself: Xiaomi explained that the whole process of manufacturing it involves using their own self-developed glass processing equipment, hot bending under 800°C high temperature and pressure, four different polishing tools, up to more than ten complex polishing procedures, and thousands of attempts in order to get it right.
With its portless, buttonless design, Xiaomi incorporated various technologies like ultra-thin piezoelectric ceramics,film display acoustic technology, third-generation under-display cameras, wireless charging, eSIM chips, and pressure-sensitive touch sensors into the Quad-Curved Waterfall Display concept.
Just like with vivo’s Apex 2019, the Quad-Curved Waterfall display will remain a concept for Xiaomi, but their latest innovation does give us a preview on the future of smartphones. Paired with the Mi Air Charge that they demonstrated last week, Xiaomi is definitelty cooking up a lot of interesting things that are worth looking forward to.
