At the OPPO Future Technology Conference，OPPO debuts the OPPO X 2021 scroll-screen phone，Apply the stepless OLED flexible scroll screen to the mobile phone，This phone has a deformable precision structure similar to the folding screen design，Can switch between normal form and large screen form，Offers very different usage。However, its design concept and technical specifications are completely different from the folding screen.，Compared with the current folding screen mobile phone, it has a thinner body，And no folds like foldable phones，More can bring automatic retraction，The experience seems to be more exciting。
OPPO X 2021 scroll screen phone，It has two modes of use: closed and expanded，When closed, it looks like a normal mobile phone，You can think of it as an OPPO Find X with a curved screen，When unfolded, it is a large-screen device，Just like a foldable phone。without restarting，OPPO X 2021 is no different from current phones，The screen size at this time is 6.7 inches，And when unfolded, it reaches 7.4 inches。
But the OPPO X 2021 scroll screen phone and the folding screen model are completely different things，The first is that the screen has no creases at all.，The visual effect is better when using，Look at it from every angle，All you see is a complete screen，There is no light refraction caused by any folding。
Its experience in both expanded and collapsed states is also better，especially when folded，It can almost be used as an ordinary flagship-level candy bar phone，It does not have the heavy feeling of the folding screen model at all，Somatosensory weight is more than 200 grams，Definitely much lighter than the folding screen design。This kind of portability can be used as a normal ordinary model.，Will not cause any extra burden on carrying。
Thickness，OPPO X 2021 scroll screen mobile phone is indeed much thicker than ordinary mobile phones，We must admit this，After all, there is a special mechanical structure inside to control the opening and closing of the screen.。But here we have to say，Compared with the current folding screen mobile phone, it is still much lighter.，Better than a foldable phone, at least for pocket comfort。
The left and right sides of the screen of the OPPO X 2021 scroll screen concept machine are different，On the right is a fixed surface，On the left is the inner volume area。when we expand，The area that is shrunk inside the fuselage will be slowly pulled out from the inside，Fully expand this flexible screen，This structure is also the key to its absence of creases。And the radian and thickness design of the machine，There are also factors to consider in this regard，It is close to the flexible diameter of the OLED flexible screen after being stressed，Make sure that the flexible screen hardly creases after bending。
To make the screen softer、Expand in a smooth way、put away，OPPO structural engineers have designed the "Roll Motor" power scheme in a targeted manner，Output constant force through two drive motors built into the body，Directly used to expand and collapse the screen，Make the screen evenly stressed during movement，And can effectively prevent the screen from being damaged when suddenly stressed。This is somewhat similar to the design of OPPO Find X，Both are controlled by electromechanical transmission to control structural changes，Reduce human interference，So that the entire process of unfolding or retracting is completely uniform，thus prolonging the service life of the structure。
A pulley bearing with a diameter of about 6.8mm is built into the movable side of the OPPO X 2021 fuselage structure，The screen always moves along the central axis，Presents a U-shaped structure when the screen is folded。6.8mm is closer to the bendable diameter of the OLED flexible screen after being stressed，Make sure that the flexible screen hardly creases after bending；Pulleys make sure the screen is smooth as it bends、smooth。And many structures and dual speakers are also placed in this part，Make full use of the interior space of the fuselage。
And inside the fuselage we can't see，Except for the pulley bearing part，There is also a "cross wood comb" design，To ensure the structural strength of the whole machine。OPPO named it as a dual-matrix embedded clutch structure，Two left and right pallets are designed inside the fuselage，Supports the screen effectively in any form：when the screen is closed，Two pallets can be seamlessly spliced into the same plane；when the screen is expanded，One side of the pallet slides out synchronously，The left and right pallets support the unfolded screen with zero step difference，keep the screen smooth。
Screen dynamic area skeleton overlay，High-strength steel as the main material，The thinnest part is only 0.1mm，Linear pattern etched to match the surface of the laminate，Under the premise of providing sufficient support, it does not increase the screen bending resilience。side view，Skeleton stacks in the dynamic area of the screen are like the tracks of a tank，Provides reliable protection without increasing resistance。
Unique design on the back of the fuselage，A diagonal line divides the phone into two areas，The unfolded performance is natural，Beautiful shape when closed。In addition, because the mobile phone needs to be equipped with a complex mechanical structure，So there is also enough interior space，So that the camera of this concept machine is completely flush with the back。
Overall，The OPPO X 2021 scroll-screen phone has a novel design，In line with the current direction of mobile phone screen innovation。Scroll-style unwinding is smoother，The visual impact of the screen is higher than that of the folding screen design。Compared to current folding screen phones，We obviously prefer to try scrolling phones。
How is the experience of OPPO X 2021 scroll screen mobile phone，We also tried it through a simple start，Let's talk about our own feelings，On the whole, it is easier and smoother than the opening and closing of the folding screen。
The opening and closing of the OPPO X 2021 scroll screen mobile phone can theoretically be done with one hand，It uses touch gestures in the fingerprint area on the right side of the fuselage to achieve，Swipe up to expand，Swipe down to close the screen。The sliding of the screen is uniform，no sudden force changes。
OPPO X 2021 scroll screen concept machine is different from the deformation method of folding screen，It is a smooth change of screen size，This change will not affect current application usage。In the interface change of the system，we can feel，The change of various icon distances is gradual，Let's embrace screen size and ratio changes in a very natural way。
in the expanded state，OPPO X 2021 screen can reach up to 7.4 inches，The screen ratio has also reached 4：3，Have a better visual experience。Compared with the current folding screen，OPPO X 2021 brings good all-in-one，no hinged structure，no crease，And the body becomes thinner，feel better。
Not only in the system interface，The scroll screen for OPPO X 2021 OPPO also brings application optimization。in a variety of common applications，OPPO X 2021 scroll-screen phones can make this smooth size and proportion transition。
Here we demonstrate through web browsing，Let's focus on the changes in text and pictures，The zoom of the picture is very natural，Either zoom in or zoom out，No problem with proportions。The text processing is more artistic，Gradually extend or wrap from the edge of the screen，even in dynamic line breaks，It will not affect real-time reading。Compared to the folding screen，This transformation will not cause pauses in use，Rather, it creates a seamless experience。
The same can be done on the camera interface，Especially suitable for use when shooting video content。We all know that the proportions of moving video and still photos are different，The experience of shooting video on the big screen is better。on the switch here，OPPO X 2021 scroll screen phone adds a layer of frosted glass special effects，Makes the change of the aspect ratio less obtrusive。
Screen switching on video playback，is our most satisfying experience，It almost perfectly realizes the content switching between the large screen and the small screen，Absolutely will not affect the current viewing experience，Open the screen to reach 4：3proportion，More than just expanding the screen，It also reduces the black borders of the screen。
In the fully expanded state of OPPO X 2021, the keyboard of the input method also becomes a full keyboard，In the setting interface, the setting options and content are also divided into left and right sides.，It will be more convenient to operate。
In fact, we look at the various screen switching experiences of the OPPO X 2021 scroll screen mobile phone，can be found to present a theme，Seamless and smooth switching without interrupting the current usage，This experience has never been seen before。The OPPO X 2021 scrolling screen concept machine may in essence be the same as the folding screen mobile phone, which is the concept of screen deformation conversion.，But the technical presentation and experience are completely different。
OPPO X 2021 scroll screen phone features smooth screen changes，The user experience in both small screen and large screen modes surpasses the folding screen，This is true for both switching experience and visual experience。The internal electric structure makes the screen change very labor-saving，The smooth process experience is unmatched by folding screens。Apparently OPPO uses an innovative approach，Solve the disadvantages of folding screen design。
As for what we like most about the OPPO X 2021 scroll-screen phone，is that it is sufficiently portable，Especially when compared to folding screens。OPPO X 2021 scroll screen phone is much thinner in small screen mode than when folded screen is folded，Can be used as a candy bar，Have a way of using a popular mobile phone。It really is a big screen device when the screen is unfolded，The visual experience feels great。
OPPO X 2021 scroll screen mobile phone brings a new form of mobile phone，Compared to a folding screen with a fixed screen size，Scroll screen infinitely adjustable between min and max size，for productivity、entertainment、Daily use brings more possibilities。OPPO relies on strong R&D strength，The pursuit of various "black technologies" on mobile phones has not stopped，It is these "black technologies" that bring a better mobile phone experience，It has also led to changes in the industry。
OPPO X 2021 scroll screen phone is just a concept device，But it does give us a design idea for future mobile phone screens，Combined portability and practicality。mobile phone as concept，It also has various deficiencies，Like we want it to be more portable，The optimization of the border can also go further，It can also be more flexible in the size change of the screen。Fortunately, it's just a concept phone，What it gives us is a way of using mobile phones in the future，In view of OPPO's technological excellence，We can fully expect OPPO to complete the mass production of the scroll screen design in the future，At that time, its mature experience will be more expected by us。
