Oppo X 2021 is another concept phone with a scroll screen

In recent years, as the technology of flexible display panels has become more and more mature, various cell phone manufacturers also want to expand the display area as much as possible within the acceptable size. By 2020, the development of the second generation of folding screen mobile phones can no longer be considered new. Where can I go next? Maybe Oppo and TCL (and maybe LG) have found their way.

In March this year, TCL showed a series of conceptual mobile phone designs based on a pull-out screen. The right side frame can slide out. During this process, the hidden panel on the left rear side in a curled shape will be pulled out. After being lowered to the end, the screen will change from the size of a normal mobile phone to almost the size of a small tablet. The new Oppo X 2021 concept machine presented by Oppo at today’s Future Technology Conference is essentially the same as TCL’s plan in terms of implementation. It also hides part of the panel in the car like a scroll. In standard mode, it will display a 6.7-inch screen. After fully opening, the entire 7.4-inch OLED can be viewed fully in front of your eyes. And the best point is that the device supports continuous adjustment between these two sizes, which means that you can freely adjust the screen size according to your needs.

According to the official introduction, Oppo X 2021 uses the integrated double Roll Motor motors to control the retractable screen. They can continue to exert a constant force during operation, so that the screen can maintain a uniform force when pulled, which can avoid damage caused by a sudden impact. On the left side of the phone, there is a pulley with a diameter of 6.8mm. According to the factory test, this size can effectively ensure that the panel “hardly wrinkles” after folding (this is a big advantage over the current foldable mobile phone.) And can always maintain a “smooth smoothness” during the process of folding. curl. Oppo claims to have 12 main patents related to the reel structure, while the Oppo X 2021 concept machine involves 122 patents.

In addition, Oppo uses the so-called “double matrix built-in friction structure” inside the panel, which consists of two pallets, which is a bit like a pair of combs facing each other in shape. When the Oppo X 2021 is in mobile phone mode, the “comb teeth” of the two “combs” will interlock to form a relatively complete resting surface. When switching to tablet mode, the “comb” is separated from the screen, in this state the two parts are each responsible for supporting the left and right parts of the entire panel. At the same time, Oppo has also enabled the “dynamic bezel” design of a combination of a fixed frame and a sash frame on this concept phone, which allows the sash frame and rear glass battery cover to accompany the screen during warping. of the device. Mobile, it can provide more reliable support when the panel is open.

In order to prevent the flexibility of the flexible panel from being affected by the resilience and overall increase in the thickness of the screen after folding, Oppo X 2021 also has a Warp Track screen dynamic zone frame integrated with steel as the main material. Its thinnest part is 0.1mm thick. With the linear pattern etched on the surface, it can provide reliable support and protection like a “tank rail” without adding additional resistance to panel flex.

It is worth mentioning that unlike TCL, which so far has only shown prototypes, Oppo has directly supplied a working real machine. According to official demonstrations, sliding your finger on the right side of the Oppo X 2021 fuselage can trigger the retraction of the screen. During this process, the system will automatically adjust the image. For example, the web page you are browsing will shrink the content displayed on the page, and the movie being played will automatically adjust to an appropriate ratio as well. However, the official did not disclose when or even if this concept car will go into mass production. CEO Chen Mingyong just said he hoped he could “see you at the right time”. If it can finally be realized, consumers will be able to have an interesting deformer option in addition to folding screen phones.
