1: loss rate is the key;
First of all, we should know that any part has its own loss rate. For example, when we used to use touch-tone mobile phones, each case had its own loss rate, which was about tens of thousands of times. These boxes will be lost or damaged. This is a natural phenomenon, and I think the folding equipment has a good folding effect, but it is also difficult to break through this technology, mainly because it also has its own loss force when folding. And especially the screen, you should know that the unit price of the screen is very expensive now. And there are many parameters of the screen, including the quality of the screen, so it is very difficult to break through the folding device on the screen.
2. Technical difficulties:
When we put forward a new concept, there will be many technical difficulties at this time. We should not think that the new concept is just as simple as it seems, and the implementation process inside is very difficult. To put it simply, when we first launched a comprehensive mobile phone, in order to achieve a real comprehensive screen, we launched a pop-up camera. It was really useful, but why didn't it be produced later? Mainly because this kind of pop-up camera has a large loss rate, which is more troublesome to maintain and adds thickness to the mobile phone. These are actually technical difficulties, so we rarely see pop-up full-screen mobile phones later.
So you know, any new technology, just put forward, is very difficult to achieve. Moreover, it is understandable that a new technology will have many problems just after it is put on the market. Therefore, when new technologies are introduced, don't buy them at the first time. Of course, if you have money, you can buy it directly. After all, money can be willful. However, as a general user, you can keep a waiting attitude, because the new technology just launched will inevitably encounter many problems, and the technology will gradually mature when the government slowly fixes these problems.
