Sony brings the distinctive 21:9 aspect ratio to its new flagship Xperia 1 smartphone. The screen is a 6.5-inch 4K OLED, which is a big clue to Sony's main target audience: video creators and viewers. It's a big step up from the 6.5-inch Xperia 10 Plus, which has a much lower resolution and uses an IPS panel.
