The Oppo X 2021 concept phone is back – originally showcased at Inno Day 2020, the company is now revealing more details about its rollable phone at MWC Shangahi 2021. Here is a short video that explains how the display goes from 6, 7 “to 7.4”.
The action is powered by two roller motors. They use cogs that mesh with the so-called Warp Track laminate, which is similar to the timing belt. The laminate is made of high tensile steel to allow it to be both strong and thin – at its thinnest it is only 0.1mm but is still strong enough to support the screen.

Whether retracted or extended, the screen is also supported by the 2-in-1 plate. It is made up of metal strips that interlock, allowing them to slide over each other as the roller motors change the width of the screen. phone.
Oppo engineers settled on a 6.8mm axle after extensive testing. This allows the flexible OLED panel to roll around the axis without the formation of folds while maintaining a reasonable thickness.
By the way, the Oppo X 2021 was featured in Oppo’s demo of its aerial charging technology.
