What are the advantages of various brands of foldable screens? KTBABA will continue to discuss it.
 
In the past two years,  foldable screen phones have been released one after another. They may be different in form and their respective focuses are also different, but there is one thing in common: they all believe that the next form of smartphones should indeed be in the world of foldable screen mobile phones.

Take the foldable screen mobile phone launched by Rouyu as an example. Its foldable shape is slightly "crude"-directly "bending" a large screen. The folded shape looks a bit rough, and its practicality is relatively poor.
 
As a major international manufacturer of SS  mobile phones, there are currently two types of foldable screen mobile phones launched. One is the Galaxy Z Fold series with an "inward fold" design. The latter effect is also flawed, but it also currently has more mobile phone brands with foldable screen technology.
 
SS second foldable-screen phone is a similar retro "flip phone"foldable design machine: Galaxy Z Flip. After the release of this machine, many users are concerned about not only the hinge problem but also whether the screen crease is the same as the Galaxy Fold. The same is obvious, but even if SS uses flexible glass this time, the creases on the hinge part are still obvious.

So far, Huawei has also launched several generations of foldable screen mobile phones designed with external foldable schemes-Huawei Mate X series. After foldable, it is almost the same as ordinary candy bar phones. After unfoldable, the screen can reach the size of the smallest tablet computer, supplemented by more mature Cross-terminal, multi-screen collaborative program design, and top-level hardware collocation。

Patent information of "Foldable Electronic Equipment and foldable Screen Installation Structure" by Huawei Technologies Co., Ltd. was published. The patent publication number is CN112466205A, and the application date is September 2019. Huawei uses this technology to "eliminate fold marks"
The patent abstract shows that the application provides a foldable electronic device and a  foldable screen installation structure. The foldable electronic device includes a housing and a middle frame. The screen is flexible and bendable, and the foldable screen includes a flexible cover and a flexible display module, and the flexible display module performs display through the flexible cover.
Through this patent, Huawei can greatly reduce the damage of the current foldable screen, which can greatly reduce the deformation and protrusion caused by the repeated bending of the screen, and further enhance the practicality of the foldable screen. I look forward to seeing this on the Mate X3. The application of this technology.

Some analysts predict that Apple may launch an iPhone smartphone with an 8-inch OLED flexible screen in 2023. On Tuesday, the United States Patent and Trademark Office (USPTO) revealed the company's patent for an "electronic device with a sliding expandable display."
As can be seen from the patent illustration, Apple has proposed a unique flexible screen design, suggesting that this conceptual device can roll up the screen and store it in shell-like a scroll.
The shell part contains slidable elements, and with the stretching of the body components, the flexible screen in a curled state can also be pulled out.
  In the compact (storage) state, the device can light up a small part of the screen as needed. In addition, to ensure the flatness of the screen, there is a spring inside to exert a certain amount of force.

At present, the form of foldable is still being explored. Each mobile phone manufacturer is developing different types of foldable phones. Perhaps some users will recognize this type of smartphone, but its high pricing and expensive post-maintenance costs are all doomed. It is not a product form that can be affordable by the more general public and is more practical. KTBABA will look forward to the foldable screen with everyone, this product is expected to change the world again, and hope that in the future KTBAB can develop products that are more suitable for consumers.
