From concept exploration to technology research and development, to listing, after nearly two years of development, the wave of folding screens has become unstoppable and has become the next form of smartphone after full screen.
For a while, mobile phone manufacturers with a keen sense of smell rushed to the folding screen track. However, as of now, only five companies, Samsung, Huawei, Microsoft, Motorola, and Royole, have released folding screen mobile phones. Of course, other mainstream mobile phone manufacturers such as Xiaomi, OPPO, and ZTE are not to be outdone, claiming that they will release their own folding screen mobile phones in the future. . With the fierce competition in the smartphone market, the explosion of folding screen mobile phone products in 2021 has become an indisputable fact. So, who is the leader of the next era?
Four factors restrict the development of folding screen mobile phones
In fact, although the concept of folding screen mobile phones is hot, and although some manufacturers have released their own folding screen mobile phones, due to technical reasons, in addition to the mass production of Samsung and other major manufacturers, most of them are still seizing the concept of playing on the track and launching one after another. A PPT product that cannot be bought.
As we all know, the screen is the soul of the folding screen mobile phone, which requires not only a flexible screen, but also a perfect folding solution, sufficient screen protection, top Display effects, and the need to solve how to put a top-level set in a small body. Issues like hardware and a large enough battery. In addition, in addition to hardware problems, the UI adaptation of the device is also a big problem in terms of software. In short, the flexible screen, the protective layer of the flexible screen, the hinge design and the interactive experience are the main technical difficulties restricting the development of the folding screen mobile phone.
If you are talking about a product that represents the highest level of technology in the current folding screen mobile phone industry, it must be the Samsung Galaxy Z Fold2 5G. It not only achieves the perfect integration of high-performance 5G and other technologies with flexible screen technology, but it is also a mass-produced hot-selling model, bringing users a unique new mobile experience with disruptive technology.
What technical mysteries are hidden in the top folding screen?
As mentioned above, for a foldable mobile phone, the flexible screen is not enough to simply bend, but also a contest of comprehensive strength, and the technological precipitation behind it is by no means an overnight achievement. Samsung has been laying out the field of flexible screens since ten years ago. Thanks to years of research and development and deep technical accumulation, its folding screen mobile phones can be successfully mass-produced and lead the world. Not only that, as a world-leading screen technology manufacturer, the advantages of screen manufacturers make it firmly grasp the evolution direction of the screen, from OLED to AMOLED, from curved screen to hole-drilled screen to folding screen, Samsung has always been leading the way, the moat in the screen field. Unbreakable.
At present, folding screen mobile phones are mainly divided into two schemes: inner folding and outer folding. Undoubtedly, the external folding solution is more susceptible to external impact, sharp objects contact the surface of the flexible screen, and the risk of screen scratches is greater. The Samsung Galaxy Z Fold2 5G using the inner folding solution is much more technically difficult than the outer folding solution. It not only protects the inner screen better, but also avoids unnecessary damage to the screen caused by daily use, and the book-style inner folding is more suitable for users. usage habit.
In terms of materials, so far, the foldable mobile phones released on the market, except Samsung, all use the CPI polyimide cover material that is easy to age, low hardness, and easy to scratch. The Samsung Galaxy Z Fold2 5G uses a more advanced ultra-thin flexible glass (UTG) material cover. UTG has both the strength of glass material and the flexibility of polymer material, with high hardness, thin thickness, and strong light transmission. Features, which can effectively improve the user experience of flexible screens. This makes the Samsung Galaxy Z Fold2 5G not only more scratch-resistant and wear-resistant, but also better in terms of practicability and overall display, and it can also resist the physical damage to the screen that is common in life such as impurities and sharp-angle impacts.
When the screen refresh rate of other brands of folding screen mobile phones is still stuck at 60Hz, the Samsung Galaxy Z Fold2 5G also comes standard with a 120Hz adaptive refresh rate. Whether it is watching high frame rate videos or playing games, the large screen is smoother and silkier. For a folding screen mobile phone, it is very technically difficult to take into account the durability of the screen and the excellent display effect.
Testing folding screen mobile phone innovation standards: user needs are the premise
It is worth noting that the middle hinge is also crucial, which will directly affect the interactive experience of the folding screen mobile phone and the service life of the screen. According to netizens’ complaints, when experiencing other brands of folding screen mobile phones, when the screen is folded or unfolded, it is laborious and accompanied by a sound similar to folding hard plastic paper. Not only that, the screen does not fit well, the overall appearance is not flat, and the hinge and the screen are not flat. There are gaps, which seriously affect the look and feel and interactive experience. In the author’s opinion, in order to seize the opportunity, the introduction of products with immature folding screen technology has not brought users an experience beyond the full-screen mobile phone. Although once the opportunity cannot be seized, it will damage the brand image.
The Samsung Galaxy Z Fold2 5G is very different. It uses the industry’s most cutting-edge invisible hinge technology to make the body more beautiful, and supports multi-angle spin stops, bringing users such as selfies from different angles, adaptive split-screen operations, etc. A new interactive experience. At the same time, the addition of dust-proof fiber technology can effectively block dust intrusion and extend the life of the hinge, enabling it to withstand up to 200,000 folding times.
The improvement of smartphone technology needs to meet the needs of users as the premise, otherwise all innovation will be meaningless. The appearance of the folding screen mobile phone is to allow the mobile phone to carry more functions to meet the needs of users in various scenarios, and at the same time, it must also have the attribute of portability. Samsung Galaxy Z Fold2 5G breaks through the form of smartphones and brings a new upgrade in interaction. It not only supports multitasking, but users can find the required APP from the sidebar, drag it directly to the desktop, and maximize the advantages of the large screen , operate three APPs at the same time, work and life are more efficient and convenient. In contrast to other brands of folding screen mobile phones, there will be a sense of stuttering when changing from a large screen to a small screen or from a small screen to a large screen, and it does not even bring an experience beyond the full screen. Such a simple stacking cannot be called technology. It will inevitably become a marketing gimmick.
Of course, the Samsung Galaxy Z Fold2 5G is far more powerful than this. It also has 5G dual-mode full Netcom, Snapdragon 865+ SoC, 12GB LPDDR5 memory, UFS 3.1 flash memory, etc. These top-level configurations cooperate with each other to form a joint force for Users bring unprecedented new mobile experience.
All in all, no matter from the accumulation of folding screen mobile phone technology or global sales, Samsung is completely dominant and crushes other brands. Relying on its own strong research and development strength, the Samsung Galaxy Z Fold2 5G not only takes the lead in achieving breakthroughs in screen material and hinge technology, but also brings users a more practical and efficient interactive experience, which also makes the Samsung Galaxy Z Fold2 5G become the At present, the technical completion and interactive experience are the strongest folding screen mobile phones on the market. If you want to buy a high-end futuristic folding screen phone, I believe Samsung Galaxy Z Fold2 5G will not disappoint you.
