Is TCL developing an expanding-sliding OLED smartphone?

CNet reports that TCL was supposed to demonstrate a novel smartphone design next week (at the cancelled MWC event) that uses an "expandable" sliding OLED display. The idea is basically the same as in the first crop of foldable OLEDs - provide a phone that can open up to a tablet-size device:

Apparently TCL was supposed to show a working demonstration. Such a design will likely require a screen that is folded in two places or some sort of rollable display - which is possible but more difficult to actually commercialize compared to a screen that folds inwardly or outwardly in a single position.

Besides the new form factor, the Z Flip uses an ultra-thin glass cover - unlike the Galaxy Fold which used a plastic one. At least according to The Verge, this makes for a big improvement - it feels better, can't easily be "marked-up" by a fingernail and there's no visible crease. The Z Flip also feels much more refined - with no creaking and with a solid-feeling hinge.

Motorola starts shipping the foldable Razr 2019, initial reviews are here

Yesterday Motorola started shipping its $1,500 foldable OLED phone, the Razr 2019. The Razr 2019 features a 6.2" 2142x876 (21:9) foldable AMOLED display that folds inside, produced by BOE. There's also a regular external 2.7" 600x800 AMOLED used when the phone is closed.

Initial reviews are appearing online. Android Central's Nirave Gondhia tested one such phone, and he says that the Razr's screen feels fragile, even more so than the screen of his Galaxy Fold. While he likes how the device folds, he says that as the screen shifts along the hinge, the feedback on the screen feel strange and it feels as if the screen could be damaged by the folding over the long term.
