Why does OPPO choose to use a scrolling screen as a mobile phone instead of a folding screen?

Basically, it is to solve the durability problem caused by folding screens.

Now, people familiar with folding screen products know that whether folding outward or inward, it is easy to cause crease problems because of too many folding times, which will greatly affect the display effect of folding screen and even lead to a series of irreversible screen damage, including folding machines released by Samsung and Huawei. It can be said that it is very common to return to the factory because of the crease problem, and there is also feedback on the Internet.

The screen design of OPPO X 202 1 scroll screen concept machine is more like a scroll. The screen that is not displayed inside is rolled up and hidden inside the fuselage. When necessary, it is slowly opened by internal mechanical mechanism, and then retracted like a scroll by corresponding operation. There will be no crease problem in all aspects, and the durability of the screen will be greatly improved.

Moreover, OPPO has specially customized the power scheme of "rolling motor", the screen support scheme of "comb bed" and the lamination scheme of "warp track" to make the screen stress even when stretching, and at the same time, the seamless joint support plate arranged below can support the screen when opening and closing to prevent the screen from deforming, and there are specially designed steel materials as thin as 0. 1mm, which reduces the resilience brought by screen lamination, thus protecting the screen. This mature scheme can make the scrolling screen work normally after repeated stretching.

Scroll screen solves the defects of folding screen in many aspects, and is expected to become the mainstream design scheme of super-large screen mobile phone in the future.

First of all, it should be that there are more mobile phones with folding screens now, so it doesn't seem to make much sense to make folding screens. Secondly, folding screen is always difficult to solve the crease problem. There are creases on the screen, which affect the perception whether watching videos or playing games, so the advantages of the big screen cannot be reflected. However, scrolling does not have this problem, which ensures the integrity of the screen and the visual effect will be much better when used.

This is actually very easy to understand. The current folding screen mobile phone is still immature. Folding more than a few times will produce creases, which will greatly affect the visual experience. Especially when watching a movie with a folding screen, it's hard to have a crease suddenly on the screen, isn't it? Why OPPO doesn't use folding screen is mostly influenced by this reason, and OPPO X 202 1 scrolling screen concept machine can solve this problem well by using scrolling screen design, and then there will be no creases, so that you can experience the immersion of a real full screen, and watching movies or playing games will not be affected by creases. This is my personal understanding.

Since all the above bosses have talked about the technical principles, I will explain the benefits of scrolling screen from another angle: good-looking, loaded!

Very simple, folding the screen, you need to flip it manually to open the screen, which is consistent with the logic of using the flip phone before, and there is nothing new. But the OPPO scroll screen phone is different. Take out your mobile phone and gently slide it in the fingerprint identification area, and it will automatically open, especially in public places. The turnover rate of this operation is at least 99%, not to mention 100%, which is so handsome!

Upstairs, it is said that the current folding screen mobile phone also has hinge problems. It can be said that this is the most common defect of folding screen mobile phone except crease problem. It is very common that hinges break due to repeated bending and pulling, and some design problems lead to indirect damage to the screen. Simply put, the folding screen mobile phone with hinge design is not very durable. In contrast, OPPO's scrolling mobile phone can avoid this problem, but the strength of its bracket has also been largely considered. According to the three technologies introduced at the conference, such as "rolling motor" power scheme, "carding machine" screen support scheme and "warp track" bonding scheme, it feels quite reliable. Let's see what the feedback will be.

Folding screen is only a concept machine now, and there are still many problems that have not been solved well. The technology is not mature yet, so we'd better wait and see.
