Xiaomi has shown a concept smartphone with a quad-curved waterfall display. The screen extends over all four edges of the smartphone, leaving no room for ports in those edges.

The screen bends on all sides around the edges of the smartphone, but that is not the case at the corners of the device. Those corners are simply black in the Xiaomi examples. The edges bend at an angle of 88 degrees, just like Oppo’s concept with waterfall screen from 2019. With the concept, Xiaomi is bringing a “only screen” form factor in smartphones one step closer. The company also speaks of a unibody no-port design because buttons and interfaces in the sides are missing.

The company claims that the functions of physical ports and buttons can be replaced by ‘more elegant alternatives’. The company mentions, among other things, esim, wireless charging and pressure-sensitive sensors. In addition, the company speaks of the presence of cameras under the screen.

Xiaomi further emphasizes the difficulties of polishing solid glass that has to be bent on four sides. The company claims to use self-developed devices for processing the glass. Xiaomi does not yet give details about a possible release of smartphones with a quad-curved waterfall display. Xiaomi showed the Mi Mix Alpha in 2019, a concept smartphone whose screen was completely curved around the device. That smartphone has not appeared despite previous promises.
