The Samsung Galaxy Note Edge popularized the notion of curved displays on smartphones, and the feature has proliferated on Android smartphones in the years that have followed. Oppo is taking the curved display concept to the extreme with what it is calling the Waterfall Screen.
The curve of the display extends much further down along the sides of this smartphone concept at 88 degrees on both right- and left-hand sides. The immediate effect of the dramatic curvature is that when looked at directly from the front, it dramatically minimizes the appearance of the side bezels.
One other consequence of this display arrangement is that there don't appear to be any buttons along the sides of the smartphone -- there simply isn't enough room for them. This leads us to believe that volume and power controls must be located along the top of the smartphone, which would pose some ergonomic challenged given the extremely tall aspect ratio of the device.
At this point, Oppo's Waterfall Screen is simply a concept; however, it's highly probably that the Chinese smartphone maker is looking to adopt the tech on future production smartphones. But we should remember that Oppo has shown in the past that it is not afraid to take radical design risks.
Just last month, the company unveiled the world's first under-display selfie camerathat aims to eliminate the need for display notches, hole punch cutouts and pop-up cameras. That particular technology isn't quite ready for primetime, but future advances could lead to this tech becoming the gold standard for smartphone selfie cameras.
