OPPO releases a scroll screen concept phone. What’s the cool technology behind this phone?

OPPO released a scroll screen concept phone, which is mainly different from the common folding screen. It uses a flexible screen to play new tricks. Simply put, it uses an OLED flexible scroll screen. 1: "Roll Motor" powertrain

According to OPPO's introduction at the press conference, in order to make the screen unfold and retract in a softer and smoother way, OPPO designed the "Roll Motor" powertrain. Integration: The two drive motors built into the fuselage output a constant force to control the unfolding and retracting of the screen, so that the screen is evenly stressed during movement, which can effectively prevent the screen from being damaged when a sudden force is applied.

Two: It adopts a "dual matrix embedded clutch structure"

After experiencing the real machine on site, I found that the overall feeling of pulling out and retracting the screen is smoother and smoother, and the whole thing is completed. The degree is higher. The realization of this feel depends on a pulley bearing. Judging from the hands-on effect, it is almost difficult to detect the screen creases of OPPO X 2021 with the naked eye. The extended part is well "connected" to the original screen, without giving people a sense of visual fragmentation. According to OPPO, this is because it uses a "dual matrix embedded clutch structure." To put it simply, there are two supporting plates inside the fuselage. When the screen is unfolded, one of the supporting plates can slide out simultaneously. The left and right supporting plates support the unfolded screen with zero step difference to keep the screen smooth; when they are closed, the two supporting plates can slide out simultaneously. The two pallets can be seamlessly spliced ??into the same plane.

3: Usage effect

During the process of stretching the screen, the outer frame and back glass battery cover will move with the screen. The biggest advantage of this design is to ensure that the screen is still reliably protected when it is unfolded. This circle of "dynamic frame" will also reduce wear and tear on the edges of the screen and extend the service life of the screen.

Even as a concept engineering machine, the overall design completion of OPPO X 2021 is pretty good. The line design on the back of the fuselage is very dynamic, and the material is still glass and metal. If the secondary camera below the main camera is installed, it can basically be launched as a retail version.
