Was wondering when someone would finally do it. Rollable phones next, please?

Ever since the first foldable screens were announced in the 2010s, I’ve had this idea for a cylindrical tube-shaped phone. Tube contains the battery, cameras, buttons, and ports. Pull on a tab and the screen rolls out. Pull a little more, and now the screen is tablet-sized. Like unraveling a roll of film. I could see this design replacing foldables.

The only part I haven’t figured out yet is how to make the screen rigid enough for use. Maybe using some sort of chain-link latching system?
