TCL has unveiled two interesting foldable OLED prototype devices. The first one is a tri-foldable OLED smartphone, that has a 10" 3K AMOLED display that folds into a 6.64" one. The second is the sliding-expanding prototype we already reported on last month.

These are still very early prototype devices, reportedly the software is not taking advantage of the special display features.

TCL is both a smartphone maker and a display producer, and we are not sure whether TCL's latest prototypes use foldable OLED produced at TCL's own OLED lines (CSoT's T4 6-Gen flexible OLED line in Wuhan should enter production soon) or whether the panel is produced by Samsung, BOE or Visionox.
