Folding screen mobile phone ushers in new breakthrough

Huawei to launch three new folding screen mobile phones

Folding screen mobile phones, which have been silent for some time, are about to usher in a new round of explosion. These new folding screen mobile phones all have one thing in common: they use ultra-thin glass (UTG) as the cover plate.

Vivo plans to launch a foldable mobile phone with UTG in the fourth quarter of this year, and Xiaomi will also use UTG in its mix fold 2; Oppo plans to launch a foldable mobile phone with UTG in 2022; Another source said glory is preparing a foldable mobile phone with UTG.

Undoubtedly, UTG is gradually becoming the new favorite of mobile phone manufacturers. In different technology upgrading schemes, UTG may become the next key point of the differentiation of folding screen mobile phones.

Why does UTG become fragrant all of a sudden?

2019 is the first year of global folding mobile phone business. Mobile phone manufacturers have shown their “technical muscle” on folding screen mobile phones, including Samsung Galaxy fold, Huawei mate x, Motorola Razr 5g, and Xiaomi mix fold. As long as there is “folding screen” blessing, it will become a hot spot in the market. However, the “screen” experience of the early generation of folding screen mobile phones is not perfect. For example, the crease in the middle of the screen is clearly visible, the screen is easy to scratch, and it is not resistant to high temperature and extreme cold. All these disadvantages make the folding screen mobile phone with a price of 10000 yuan very “delicate”. The reason for the poor experience of the folding screen is the use of polyimide film (CPI) as the screen cover material.

CPI is a commonly used material in the industry before, because it has a mass production basis and performs well in ductility and flexibility. But the screen is easy to scratch, easy to produce creases, impact resistance is weak, not resistant to high temperature and extremely cold are also obvious disadvantages of CPI.

Samsung is the first company to shift the cover material of foldable smart phones from polyimide film to ultra-thin glass. Since last year, Samsung launched Galaxy Z fold 2 and Galaxy Z flip, both of which use UTG glass as the cover material, thus opening up the UTG glass market.
