New Xiaomi concept phone has waterfall display on all 4 edges
India TV NewsGlobal 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. "With Xiaomi's new breakthroughs in quad-curved waterfall displays, new possibilities are forged and critical advances are made towards the goal of a truly port-free unibody smartphone," the company said in a statement. Polishing a piece of such hyper-curved glass with a deep 88 degree bend on four sides requires self-developed glass processing equipment, hot bending under 800 degree Celsius high temperature and pressure, four different polishing tools and up to more than ten complex polishing procedures. Xiaomi last month introduced a brand new form of charging called Mi Air Charge Technology that is able to charge devices "within a radius of several metres."
