For the last two years, it's been an open secret that LG has been working on a smartphone with a rollable screen — that is, a device with a display that starts out phone-sized and stretches out into a tiny tablet. It's still not quite done, but that didn't stop LG from offering our first real glimpse at the device — called the LG Rollable — in a lightning-fast teaser during its CES 2021 press conference. While further details are scant, the LG Rollable is at least visually a tantalizing response to Samsung's slew of foldable phones.
