Xiaomi presents a new concept of phone with quad screens, without buttons, notches or ports

When Xiaomi first showed its Mi Mix thin frame concept in 2016, it has become a kind of model for phone manufacturers looking to produce phones with smaller bezels. But the Mi Mix concept was more than the incredible (for the time) 91.3% ratio between screen and body. It was housed in ceramic and the piezoelectric speakers generated sound from the metal structure of the device. Xiaomi designers moved and removed the sensors located on the top of a phone, allowing the bezels to be reduced in size.

Now, Xiaomi has another concept phone to present to the world. Using its “cascading quadruple screen” (with 88 degree curves on the left and right sides), this device has no bezels, doors and buttons. With 46 of his own patents used in the design of the device, Xiaomi claims that almost all the sides of the phone are covered by the screen. Explaining the manufacture of 88-degree glass, the company said: “88-degree ultra-curved glass has virtually broken the technological limits of glass production. Compared to ordinary curved glass, the difficulty of hot bending increases exponentially. Polishing a piece of such hyper-curved glass with a deep curvature of 88 ° on four sides requires self-developed glass processing equipment, hot bending below 800 ° C for high temperature and pressure, four different polishing tools and up to more than ten procedures polishing polishes. “

Xiaomi also made reference to some of the cutting edge technologies that worked on creating this concept phone. Solutions such as “ultrafine piezoelectric ceramics, industry-first acoustic flexible film display technology, cameras under third generation display, wireless charging, eSIM chips, pressure sensitive touch sensors and more – are seamlessly integrated, forming a visionary device , but intuitive. “
