From the design idea, we can see that the components in electronic equipment, such as batteries, circuit boards and chips, can be divided into two pieces, and the flip structure has been used in flip phones for more than ten years. But the most troublesome thing is the screen. Breaking the screen takes some effort.
Moreover, there are two kinds of mobile phone screens currently used in the market: LCD (liquid crystal display) and organic light-emitting diode (OLED) screens. The former can't be Bai Wan, because its structure is complicated and it needs a backlight module to work normally. If this screen is from Bai Wan, its backlight module will not work properly. The latter's organic light-emitting diode screen is different, it emits light through organic materials, and the structure is not so much compared with LCD. But this screen will be protected by glass, so if you want to make a folding screen mobile phone, you have to use other materials instead of glass. After the exchange, you will find that the folding can be folded, but how to fold? At this time, Samsung and Huawei have gone out of two different ways: folding inward and folding outward. These two folding methods have their own advantages.
Now is the era of full screen, and there are also folding screen mobile phones, which are very expensive. Maybe in a few years, with the further development of technology, we can use cheaper folding screen mobile phones.
