The really borderless smartphones are not very far. As proof, here is the concept Vivo Apex FullView which shows that all the necessary technologies are ready.
If the new Zenfone Asus have created the surprise Tuesday night, another manufacturer is talking about him at MWC 2018. Vivo – which is not distributed in Europe, but which is fifth in the world – has actually presented a worthy prototype sci-fi movies. With the Vivo Apex FullView, the brand demonstrates that a truly borderless smartphone will soon be a commercial reality. The prototype shown at the Mobile World Congress still shows a border of the lower part measuring 4.3 mm, but the manufacturer says it can reach 1.8 mm on all four sides of the screen, which would bring the share of the screen (screen -to-body ratio) at over 98%, the highest in the world.
How Vivo released the front
To design such a smartphone without border or notch, Vivo has combined several innovations. After the Vivo X20 Plus UD CES 2018, the first mass-produced smartphone integrating a fingerprint sensor in the screen, the manufacturer now offers the technology Half-Screen In-Display Fingerprint Scanning. As the name suggests, it allows to unlock the device by placing a finger, or even two, in an area occupying not a half, but a third of the screen. It's still not as fast as a small localized sensor, but one can imagine that this will eventually unlock the device in full transparency, simply by catching it or sliding the lock screen.
The front camera is retracted in 0.8 seconds.
As for selfies, Vivo offers a retractable front camera that slides in just under a second (0.8 s) when needed, then retracts into the top edge of the camera. In 2015, Huawei proposed another solution, with the Honor 7i, whose back sensor rotated 180 degrees. It was probably more fragile, but we had the best of technology at the back and front.Rest the speaker and the sensors. Vivo only indicates that it has hidden the proximity sensor and the brightness sensor, without specifying how. For the loudspeaker, the one with which you phone when you wear the device to the ear, manufacturers like Xiaomi use the phenomenon of bone conduction, which requires holding the phone firmly against the skull. Vivo offers a technology called Screen SoundCasting, which is to vibrate the screen, which turns it into a speaker membrane and makes its use less demanding.
Soon a really borderless smartphone?
Vivo indicates that it does not intend to market this product in its current form. The Vivo Apex FullView is unfortunately only a concept. But it shows that we now have all the technology needed to design a truly borderless phone. It is therefore only a matter of months before such a smartphone is finally marketed.
