TCL's rollable phone demo allegedly leaks onto YouTube

Never mind the foldable, here comes the rollable. This, at least, is the main message behind a new video posted by a leaker calling themselves Fold Universe. It purports to contain part of a TCL conference in which this display specialist showed its extending-screen phone prototypes off.

TCL has previously been confirmed to have next-level flexible-display phones like this in the works. They are extremely rare concept devices (the only other OEM being linked to such a project being LG) that may allow an AMOLED display to adopt different lengths in reponse to changes in their UI, thus providing what may become the main alternatives to devices such as the Galaxy Z Folds or Flips of the world in the future.

The new leaked video appears to show that TCL's extending (or "Cloud") AMOLED display might come contained between 2 "rollers" that allow the screen to scroll outwards smoothly and then furl up again, to an apparent extent of 17 inches. Alternatively, it might be found in a more conventional smartphone-like form-factor that can support the rolling action.

This most recent tip on how personal devices might evolve also seems to show that TCL's rollable prototype can also reproduce something of a full UI, which seemed capable of adapting to the scrolling motion. Then again, the OEM may have some time to fine-tune it before it sees an actual launch as a real-life project.
