Factors Affecting The Use Experience Of Folding Mobile Phones

In the development of folding screen mobile phones, four important factors affect the use of mobile phones in our lives. Screen manufacturing technology, screen material, anklet design technology and software optimization bring different experiences when using mobile phones.

Screen Manufacturing Technology

Mobile phone screen manufacturing technology is very important. Good screen manufacturing technology can ensure that the mobile phone screen can withstand the normal use of the mobile phone. As delicate things can be bent, so the screen can also be bent. Most of the current folding screen mobile phones use fragile glass to fold the screen. Modern manufacturing techniques allow the screen and glass to be held together, reducing the chance of damage. For example, Samsung’s Z Flip phone uses its own product technology to ensure the ease of use of the screen. This is because people know that delicate screens can be easily damaged. If you touch them too hard, they may break. So what is Samsung doing? It is made by coating 0.7 mm thick glass with plastic. This layer ensures that the screen is well protected without direct contact with the outside world. Of course, this technology also has some drawbacks. B. It makes the phone thicker, so the phone screen is more likely to suffer irreparable scratches. But as new manufacturing techniques are developed, the toughness of glass will continue to increase, meaning there will be no need to use plastic for protection. This will also solve the problem of foldable phone screen. Phones with folding screens can be used like normal phones, but be careful as the screen gets easily damaged.

Screen Material

When we look at the new folding display phones, the use of screen material also attracts attention. The use of more advanced material technology can reduce the price of a phone and extend the life of the phone, as accidental damage to the display does not lead to the phone being discarded. As explained in the article: The main problem is this: The chemical bonds of a material can only be stretched to a certain limit before they break. This concept is called tensile strength. But with thinner glass sheets, less material can be stretched over the same area, fewer layers can be folded, and the chemical bonds stretch less, Mydlak says. This reduces the tensile stress on the glass, allowing it to bend more before breaking. According to Zhujun Hu, associate professor of materials science at the Massachusetts Institute of Technology, physics students learn that tensile stress is linearly related to thickness, so making glass thinner is one of the “two most important tricks” of bending. Experts say that by reducing the thickness of the glass to less than 100 micrometers, which is equivalent to the thickness of a human hair, it can be bent enough to be used in major foldable devices. To protect the mobile phone display from oxidation or corrosion caused by external oxygen or water vapor, the largest surface of the display is covered with a protective layer. This technique is called encapsulation. In traditional mobile phones, the top layer is sealed with glass, but a rigid glass case is also not suitable for a flexible foldable display. One of the main solutions is so-called Thin Film Encapsulation (or TFE). As the name suggests, it is a thin, translucent, anti-rust plastic film that is used as a protective film for mobile phone screens. If you want a mobile phone that can fold inward without large gaps in the hinge, we’re talking tens of micrometers. With the right materials, you can make a thin and strong mobile phone screen.

Foot Chain Design Technology

The design of mobile phone anklet is also basic. The function of the anklet is to protect the screen of the mobile phone, which can be completely stored in the folding compartment of the mobile phone. The anklet connects the two parts of the phone and also supports the screen. In early research, the mobile phone screen played the role of connecting the two parts of the mobile phone. However, with the development of anklet technology, it was found that if only the screen is used to connect the mobile phone, the appearance of the mobile phone will be very ugly, the screen will be easily broken, and the mobile phone will be damaged. After attaching the folding display to the anklet, the integrity of the phone improved dramatically. First: It’s too strict. The stiffness of this hinge improves the overall feeling of reliability and durability, but it also makes it difficult to open the phone with one hand. You can do it, but it takes a lot more force than you expect and it will fly out of your hand. In most cases, it is more convenient to open the Z Flip with two hands. There are two reasons for this. When pressing the thumb to initiate the folding process, there is a risk of damaging the plastic of the screen under the thumb. Since then, people have learned that although the presence of ankle chains increases the reliability of foldable mobile phones, people cannot buy them due to their relatively high price and heavy weight. However, with the development of mechanical engineering, the lightweight design of anklets will further improve the design of mobile phones.

Software Optimization

The final factor affecting the use of folding display mobile phones is software optimization. It is known that the screen ratio of most mobile phones is about 21.5:9, but the screen ratio of foldable mobile phones when unfolded is about 1:1. Therefore, software optimization is very important. The sound system can improve the overall experience of the folding screen mobile phone. The current solution consists of two parts. First, the system. When you turn on the mobile phone, the screen becomes larger. When the screen becomes larger, the time, power, control center, home screen, etc. become larger. At present, Huawei’s Android system and Hongmeng system have the best design. Mi has a solution for this. We have developed our own system. Once the screen is built, it can become a system similar to the operating interface of a computer, with more convenient operation logic and better interaction design. The second part is the application. Because the app needs to adjust for screen expansion. If properly adjusted, it can make full use of the abundant space to display more content instead of expanding the screen blindly. At present, WeChat and other applications have completed the optimization of most folding screen mobile phones, thereby improving the experience.
