A working OPPO X 2021 unit is seen in the wild, along with its alleged durability rating
OPPO unveiled the X 2021 at its Inno Day 2020. It is this OEM's take on the rollable phone, a potentially emerging use-case of flexible OLED in next-gen devices. This idea is an alternative to foldables, in that it can roll or slide outward to give a larger display size at need.
Recently, a OPPO hardware engineer called Jin Xiang reportedly brought a working version of this device to a press conference. This demonstration apparently came with claims that the rollable phone had been tested for "100,000 curls", which could be interpreted as extending motions of this volume.
The X 2021 was also described as robust enough to withstand 5 years of use, during which the owner could blithely exceed the rated number of "curls" without damage to the phone. It has also featured in a video in which its rolling motion is showcased, while also showing a video in one shot. This action is, as OPPO mentioned during its developer conference, controlled by motors.
The content seemed to be able to adjust to the screen's changing size, adopting different aspect-ratios as it did so. The aysmmetric rear panel of the X 2021 was also shown, revealing its white-and-silver finish and rear camera module of indeterminate sensors.
