*Vivo has taken the wraps off a concept smartphone at the MWC 2018, which the company claims to have a screen-to-body ratio of 98 per cent.Vivo says its FullView display technology is the result of new engineering breakthroughs in camera, speaker, and sensor elements. To achieve an incredible 98 per cent screen-to-body ratio, Vivo has opted for an OLED panel for the display. The concept device features the thinnest bezels ever seen on a smartphone. The top and side bezels measure only 1.8mm while the bottom bezel is 4.3mm. But there’s more: Vivo has removed the integrated speaker into the front of the display and instead the screen acts as a speaker. This has been achieved through what the company calls the Screen SoundCasting technology. Vivo hasn’t provided any details on the availability of the Apex FullView smartphone, or how much it will cost. For now we know, Vivo Apex FullView may never see the light of the day.
