The scrolling screen is put on hold, and OPPO moves to the folding screen.
OPPO X 202 1 demo
Last year, OPPO announced its brand-new concept machine OPPO X 202 1 at the future technology conference, and the retractable screen like a scroll became the focus topic. This is a very bold attempt, but also left a deep impression on people. You can freely stretch and push back the control screen size, and switch from 6.7 inches to 7.4 inches at will to maximize the flexible screen.
Scroll screen allows us to see the big screen mobile phone that may appear in the future, but the technical difficulty can be imagined. Shen Yiren, former vice president of OPPO, also said in Weibo that at this stage, such a screen has not improved the user's experience, and the durability, final thickness and crease on the screen are all very important issues.
Recently, OPPO announced a patent for its own folding screen, and predicted that it will be unveiled in April. Although it is not the expected OPPO X 202 1, it can also be seen that OPPO has not given up the research and development of organic light-emitting diode flexible screens. What kind of surprise can OPPO bring to us by joining the folding screen market this time?
Patent introduction of OPPO folding screen
OPPO's folding screen mobile phone chooses the way of folding up and down. In 20 19, the folding machine announced by OPPO at that time was external folding, but this folding method would make the flexible screen very fragile, thus greatly reducing the life of the screen. Therefore, in this patent, OPPO chose to fold inward. In the storage state, the screen is curved, and with the protection of the shell, the durability is greatly improved.

In the choice of hinge, OPPO adopts bimetallic spiral hinge, and the screen of the hinge part will not fit completely when folding, thus making the screen have a certain curvature. This design is not only to increase durability, but also to make the screen stretch more smooth.
When we use the folding screen, of course, we don't want to hear the click sound, and the design of double hinges also solves this problem well. It also allows users to fix their phones at 30 degrees, 60 degrees, 90 degrees and 120 degrees without affecting their normal use.
Technical problem, the opponent has taken the lead.
Long before OPPO, Huawei and Samsung have already launched their own folding screen phones, and they have been sold in official website. Comparing the design of OPPO, let's also look at the difference between Huawei and Samsung's folding screens.
Huawei Mate X2 folding screen mobile phone
Huawei folding screen mobile phone adopts the way of folding left and right, with internal and external screens. Compared with OPPO's folding up and down, Mate X2 has a larger screen. For users who like big screens, Huawei's folding screen will undoubtedly make people very excited. In addition, Huawei's double wedge design makes the screen have no gap after folding, and the thickness of both ends of the phone is the same. In order to ensure the durability of the screen, the hinge thickness of OPPO will be slightly higher than that of the other side, but whether the upper and lower folding thickness is uniform will not particularly affect the experience.
Compared with folding up and down, the advantage of folding Mate X2 screen is that users can use tablet and mobile phone at the same time. Both internal and external screens can display information, which is suitable for a wider range of daily scenes, and the internal screen can also be well protected. But everything has two sides, and the inner screen needs to be unfolded before it can be used, which actually increases the user's use cost. The design of the two screens also occupies a lot of internal space, so it is difficult to reduce the weight and thickness.
Samsung Galaxy Z Flip 5G renderings
OPPO's design is similar to Samsung's Galaxy Z Flip 5G. The advantage of folding up and down is to make the whole model look small and bring portability to the extreme. Samsung chose a hidden hinge. When folded and closed, there will be obvious shaft arc at the hinge. OPPO uses a sliding type, and the hinge can be pulled out separately, which makes the whole mobile phone look flatter after folding. Samsung just fixed 75 degrees and 1 15 degrees.
What should the folding screen look like under the general trend?
In addition to OPPO, Huawei and Samsung, many other manufacturers also have their own patented folding screen designs. When the screen ratio is close to saturation, folding screen is undoubtedly a better development trend in the future. However, there are many problems worthy of our consideration. The first is the meaning of folding screen to consumers. You should know that the most important thing about mobile portable devices is portability and functional practicality. So what should the folding screen look like in the future?
First of all, on the screen, whether it is folded up and down or left and right, it is difficult to avoid creases and longevity, which can be said to be a very fatal shortcoming in the user experience. In the future design, we should consider how to hide the crease and improve the service life as much as possible. Xiaohe believes that the folding screen inside and outside brings greater resolution, but it also brings problems such as image quality, power consumption and weight. If these problems can be solved, then the dual experience of mobile phone and tablet is also a very wonderful idea. If the model can be compressed to the limit size, folding up and down can also have a good portable experience.
Then, in terms of function, the special screen should be matched with unique application functions to reflect practicality. Internal and external dual screens undoubtedly increase the cost of users' choice, and how to deal with dual-screen information is a problem that manufacturers should consider. Folding up and down mobile phones need to have different functions from ordinary straight machines in order to be more popular with consumers.
Now it is still speculation about OPPO's folding screen mobile phone, and it is still unknown which functions will be integrated. Folding screen is a wonderful technological breakthrough, and there is still a lot of room for imagination in the future development of mobile phones. Every folding screen mobile phone will bring new experience improvement, and Xiaohe is very much looking forward to what surprises OPPO will bring.
