When Xiaomi first showed off the thin frame of the Mi Mix concept in 2016, it became a kind of template for phone manufacturers who want to produce phones with smaller frames. But the Mi Mix concept was about more than the fantastic (currently) 91.3% ratio between screen and body. It was housed in ceramics, and the piezoelectric speakers generated sound from the handset’s metal frame. Xiaomi designers moved and removed the sensors located on top of a phone so that the edges can be reduced in size.
Now, Xiaomi has another concept phone to introduce to the world. Using the “square bow drop screen” (with 88-degree curves on the left and right sides), this handset has no frames, no ports and no buttons. With 46 of its own patents used in the design of the device, Xiaomi states that almost all the sides of the phone are covered by the screen. To explain the production of 88-degree glass, the company said: “The 88 ° ultra-arc glass has almost broken through the technological limits of glass production. Compared to ordinary curved glass, the difficulty of hot bending increases exponentially. Polishing a piece of such hyperbending glass with a deep bending of 88 ° on four sides requires proprietary glass processing equipment, hot bending below 800 ° C high temperature and pressure, four different polishing tools and up to more than ten complex polishing procedures. “
Xiaomi also took note of some of the groundbreaking technologies it worked on to make this concept phone. Solutions such as “ultra-thin piezoelectric ceramics, an industry-first flexible film display acoustic technology, third-generation sub-display cameras, wireless charging, eSIM chips, pressure-sensitive touch sensors and more – are seamlessly integrated together to form a visionary yet intuitive device.”
Thanks to its success in India, the company has rapidly risen in the lists to become the third largest smartphone manufacturer in the world. Of course, this nameless concept, if it ever becomes a reality, will not be one of Xiaomi’s popular value for money models.
