Rolling, as the word implies, is very different from folding on a mechanical level, but the overall effect is similar when it comes to smartphone screens. Essentially, not unlike current foldables, the Phantom Ultimate is able to adjust its screen size between 6.55-inches to up to 7.11-inches.
What sets this particular approach to screen resizing apart is the way the full screen wraps around the phone when it’s retracted, then quickly (within approximately 1.3 seconds, according to Tecno) rolls out to its fully-extended state when prompted. It also allows for a slimmer smartphone design overall, because unlike a foldable it’s not doubling up the thickness when you compact it — the screen just slides around the back. So you’re left with a roughly 10mm (about 0.4-inches) thick device no matter what screen configuration you choose.
Said screen also boasts an AMOLED display with a 2296×1596 resolution, and up to a 120Hz refresh rate. In addition to its rollability, it also claims a crisp (and double-sided when it’s compacted) view of whatever apps, games, photos, or videos you may be looking at.
