The Chinese company Xiaomi officially presented its first smartphone concept with a four-sided waterfall screen, in which its 88° curved design will allow visual interfaces to «flow over the surface of the phone like water». Almost the entire frame of the smartphone is covered by the display, and on its the case has no ports or buttons, offering users a futuristic one-piece design.

The company notes that Xiaomi engineers tried to make the smartphone as simple as possible and bring the «just a screen» form factor one step closer to reality. However, since flexible displays are part of the new standard, the biggest challenge in creating the industry’s first quad-curved waterfall screen was not the display’s curvature, but the production of the 88° quad-curved glass panel and the 3D bonding process.
