OPPO released a concept for a future rollable smartphone called the ‘OPPO X 2021
It is built with a rollable OLED display that measures as small as 6.7 inches and as large as 7.4 inches. Whether its display is retracted or not, the device features a scroll-like freely rollable display, with no “hard folding” involved.
We have developed an innovative multi-layered rigid metal to support the display. The screen includes high-precision sensors that conduct real-time monitoring, enabling it to be positioned precisely, and retract and extend smoothly.
