How difficult is it to make a mobile phone screen bend?

Information

If the smartphone can be folded together like a piece of paper, is it too exaggerated to be possible. In fact, this kind of mobile phone will soon appear in our lives. Drew Evans is a university professor in Australia. He is very firm that folding screen mobile phones will replace current smart phones in the near future.

In 2019, many mobile phone merchants want to launch their folding screen smartphones, but some mobile phone reviewers say that the security performance of mobile phone screens is still being explored. So when Samsung was about to launch their foldable screen phone, it was forced to delay the release of the phone. Everyone knows that the screen of the mobile phone is a glass screen, but why does such a screen not break when folded? Next I will take everyone to see what is called a flexible screen.

First of all, we must understand what the concept of so-called flexibility is. The flexibility of the glass screen means that the object has been deformed but it will not break because of it. Just like the Samsung Fold model, it can fold the screen at will without breaking. However, the degree of folding of the mobile phone screen will also have great requirements on the type of material it requires. Therefore, mobile phone-related R & D personnel will put forward new requirements for materials. When manufacturing a cell phone, scientists study it from different directions.

Usually most electronic products choose to use glass substrate or surface layer. Their materials are mainly hard, and the ductility of glass is rarely considered. But the curved screen is different. It requires both high thermal stability and complex electronic circuits. This will greatly increase the material requirements. This requirement cannot be met by the glass substrate alone. The addition of plastic and polyester fibers. Such a synthetic material can make the surface of the glass screen both flexible and able to withstand the high heat operation of the mobile phone circuit.

         In modern electronic technology, how to make electronic circuits fold and bend during operation is also something that mobile phone manufacturers need to consider. For example, polymers are flexible and can be bent at will, but they are non-conductive, so how to finely process the polymer so that it can conduct electricity when the mobile phone is running, this is what mobile phone manufacturers face Another big problem.

 

Therefore, materials engineers are doing everything they can to transform the manufacturing methods of existing materials and study the manufacturing methods of new materials. In fact, the bending technology has been widely used in displays in the electronics market for a long time. Many computer and television displays have long had flexible panels, but the degree of bending is not very high. In the future, when the flexible technology is developed, we can even wear electronic devices on our skin, just like temporary tattoo products. They are easy to wear, not easy to break, and more lightweight.

How to make the soft bottom of the mobile phone's flexible foldable screen is a big problem for developers. The Royal Institute of Technology team is working hard for it. I believe it is a matter of time. In the future, I believe that mature flexible screens will be widely used in mobile phones, and the communication between the body and the electronic network will become more harmonious. Let us wait and see!
