Xiaomi unveils concept phone with waterfall display on all 4 edges

Global technology leader Xiaomi on Friday officially introduced its first quad-curved waterfall screen concept smartphone on all four edges, which means there will be no port or buttons on any side of the device.

Xiaomi said the aim is to "extend the limits of the display to infinity" and enable "a true, port-free unibody design."

The 88 degree hyper quad-curved screen design allows visual interfaces to flow over the phone's surface like water.
