What’s really interesting is that the mechanism that allows the display to extend and retract is actually automated.
Oppo is looking to go in a different direction with the Oppo X 2021 concept. Instead of using a single folding display or dual screens (like the Surface Duo), the Oppo X 2021 features a scrolling mechanism that unfurls the phone display outward. This allows the screen’s size to grow from 6.7 inches to as much as 7.4 inches. You can see this in action in the Oppo promo video below. The 6.8mm diameter scrolling mechanism allows the smartphone to perform its screen « dance » without unsightly creases that we see in devices like the Galaxy Z Fold 2.
