Xiaomi QUAD Curved Waterfall Display
Today Xiaomi officially introduced Xiaomi Quad Curved Waterfall Display real-life video, through self-researched processing equipment, the glass in 800° high temperature and high-pressure heat bending integrated molding, and then through as many as ten times the complex polishing process, to polish a four-sided super curved glass.
Through 46 self-developed patented technologies, the physical buttons and all openings disappear. The original speaker and earpiece are replaced by ultra-thin piezoelectric ceramics and the industry’s first flexible film screen sound technology.
The unprecedented 88° deep curved quadruple bend screen, the screen flows around like water, from the body looks almost all screen, the bezel nearly disappeared. The ultimate screen experience behind is the challenge of the limits of the process. Through self-developed processing equipment, the glass is bent in one piece at 800° high temperature and pressure, and then through as many as ten times the complex polishing process, to polish a four-sided hyperbolic glass. After that, it has to be laminated with the flexible screen to overcome the extreme bending angle and the bending stress caused by the very small bending radius, to achieve a flawless screen performance.
Xiaomi’s four-curved waterfall screen concept phone, through 46 self-developed patented technologies, allows the physical buttons and all openings to truly disappear. The original speaker and earpiece are replaced by ultra-thin piezoelectric ceramics and the industry’s first flexible film screen sound technology, as well as a host of innovative technologies such as high-power wireless charging, pressure-sensitive buttons, third-generation under-screen lenses, and eSIM cards all rolled into one.

Let the future of Smartphones have a new direction
With it, Lei Jun also posted an article about the concept phone in his public number, saying that the screen display is one of the core strategies of Xiaomi’s cell phone, and the shape of the future phone depends on the form of the screen.
“It is because of the groundbreaking four-curved waterfall screen so that the future of the phone’s one-piece non-porous design has a new direction. This is an attempt of our screen form, but also a mapping of the future shape of the phone.” Lei Jun wrote in the text.
The screen display is one of the core strategies of Xiaomi cell phones, from Xiaomi MIX a generation of stunning full-screen, to Xiaomi 11 refreshing 13 records of the top 2K screen, in the no-man’s land of screen exploration, we continue to move forward, step by step to bring the future of cell phone form into reality.
And now, the exploration continues to extend, Xiaomi officially released the first four curved waterfall screen concept phone. The four-sided 88 ° super curved screen design, so that the picture like water flowing around placed on the table as if a crystal water drop. The surrounding bezel is almost entirely replaced by the screen, and the body has no openings or buttons, truly realizing a future design without holes.
Quad-curved 88° hyperbolic screen, manufacturing and lamination process breakthrough limit
The industry’s first quad-curved waterfall screen, a bendable flexible screen is essential, but the real challenge is the manufacturing of 88° quad-curved glass and the 3D lamination process. 88° deep curved quadruple curved glass, breaking the limits of the glass production process. The difficulty of hot bending forming and polishing is exponentially higher compared to ordinary 3D glass.
Through self-research glass processing equipment, heat bending in one piece under 800° high temperature and pressure, using four different polishing equipment, as many as ten times the complex polishing process, to polish a four-sided 88° deep curved hyperbolic glass, and behind such a piece of glass is thousands of attempts.
To laminate such a piece of 88° quad-curved glass with a flexible screen, it is necessary to overcome the extreme bending angle and the bending stress caused by the very small bending radius, adopt an innovative screen stacking design, and achieve a flawless screen performance without traces only with the breakthrough 3D lamination process.
The whole machine integrated non-porous design, the new direction of the future cell phone
The shape of the future cell phone depends on the shape of the screen. Because of the breakthrough four curved waterfall screen, so that the future of the phone’s one-piece non-porous design has a new direction.
Xiaomi four curved waterfall screen concept phone, bezel almost all replaced by the screen, through 46 self-developed patented technology, so that the physical buttons and all openings disappear.
Lei Jun talked about Xiaomi concept machine: let the future of cell phones have a new direction through ultra-thin piezoelectric ceramic to achieve external sound, the industry’s first flexible film screen sound technology instead of an earpiece, in addition to high-power wireless charging, pressure-sensitive buttons, the third generation of the under-screen lens and a host of innovative technologies in one. This is Xiaomi’s full-screen form of an attempt, but also the future of the phone form of a feel.
Xiaomi never stops exploring cell phone screens
Display technology is one of the important strategic directions of Xiaomi cell phones. As early as October 2016, Xiaomi MIX opened a new era of full-screen cell phones, with a screen-to-screen ratio of 91.3% and almost all screens on the front. In September 2019, Xiaomi Mi MIX Alpha went one step further, the body is surrounded by a whole screen, and when the screen is lit, it is like a vast universe, with no end and no boundaries, full of shocking sensations from the future.
From 2016 when Xiaomi Technology Park started to be prepared, Xiaomi labs were planned into the construction of the park. Among them, Xiaomi displays optical laboratory reaches the international advanced level, not only can test the brightness and chromaticity of the screen single point, multi-point, multi-angle but also can simulate the illumination range from 0-80000lux, 2700-10000K color temperature range under the environment, covering almost all simulated ambient light test conditions of a cell phone screen in sunny days, rainy days, noon, evening and night, to better optical parameters measurement and subjective optical performance evaluation.
In December 2020, Xiaomi 11 brought the current top cell phone screen to the public, not only with a 2K+ ultra-high-resolution display and 120Hz ultra-high refresh rate but also with accurate color reproduction comparable to professional displays. It received an A+ rating from DisplayMate, the world’s top screen reviewer, and won 13 best display records.
