Xiaomi Concept Phone Has Curved Display On All Four Edges
Xiaomi has a vision for the future of smartphones and it includes a whole lot of screens. The company is showing its newest concept device and it is a phone with a portless design and a display that rotates around all four edges of the device.
The concept, dubbed the Xiaomi Quad-Curved Waterfall Display Concept, involves the use of what Xiaomi says was a “revolutionary 88-degree hyperquad curved surface” and apparently wasn’t that easy to manufacture. According to the company, the glass was made by hot bending glass at a temperature of 800 degrees and required the use of four different polishing tools and up to 10 polishing processes.
While the construction of this display clearly involves some pretty incredible engineering, there are some questions about whether or not people actually want a phone like this. Curved display phones are actually on their way out. They look a little dated and can easily be accidentally pressed. With a device with a display on all four sides, it is hard to imagine that this is not a problem.
The other big difference between this phone and other phones on the market is the portless design. This not only eliminates the USB-C connection, but also cameras under the display, eSIM chips, pressure-sensitive touch sensors and so-called “flexible film display technology” for the built-in speakers.
Companies have been moving in this direction for a few years now, and Apple is even expected to drop the Lightning port for good in the next few years – for a completely portless phone. A portable phone could provide better water resistance and would require wireless charging as it cannot be charged by plugging it in.
Xiaomi itself recently made some announcements about wireless remote charging. The new technology, known as “air charging,” appears to be able to charge multiple devices at the same time and works within a radius of several meters. Devices can be charged at speeds up to 5W, which is not too fast. Given that you might be able to continue using your device normally while it is charging, this seems like a fair tradeoff. Xiaomi also says that this technology will work with watches and fitness bracelets and could make living rooms “really wireless”. Of course, some companies, including companies like Energous, have been working on such technologies for years and they haven’t really seen the light of day. So we have to wait and see if they can gain in importance.
