Apple is waiting on Samsung to perfect a next-generation OLED display technology that wraps almost vertically around a phone and essentially makes the sides themselves part of the screen, claims a Chinese leaker. Xiaomi's 2021 concept phone – bearing a striking resemblance to Samsung's rumored technology

" In the design – unlike a curved so-called "waterfall screen" – the main display remains completely flat, while the OLED panel bends sharply downward at close to a 90-degree angle on all four edges and corners. The idea is that those folded display sections would effectively become the sides of the device and replace the typical metal or plastic frame. Meanwhile, the display wiring and other components usually hidden behind the bezels could also be moved around the edges. The result – in theory – would be an iPhone that looks almost entirely bezel-free when viewed from the front, with the physical black border around the display reduced virtually to nothing. The technology could also reportedly facilitate an iPhone model without conventional mechanical buttons. According to the leaker, Apple has been waiting for Samsung to finalize the technology, but there are still challenges to overcome. These are said to include optical distortion and color shifts around the corners, maintaining the OLED's protective encapsulation through extreme bends, and finding suitable locations for antennas when all sides are covered by the display.
