On September 19, 2019, China's leading manufacturer of high-strength and ultra-thin touch screens/electronic glass, SCXH Optoelectronics Technology Group, released a new product "Shatter-resistant glass".
Most mobile phones nowadays use plastic or metal back covers. Metal is stronger than glass, but it shields the signal.
Shatter-resistant glass is a new product of the company`s existing mature products. The existing mature products have reached or exceeded international standards in terms of various performance indicators and production yields, and their market share ranks first in China and top three in the world. , And iterative products have significantly improved many indicators on the basis of previous generation products.
Anti-fall height increased by 5 times
Taking a mobile phone product as an example, the outermost layer of the screen is a cover glass. There are two layers of liquid crystal glass substrates under the cover glass, and the liquid crystal display material is sandwiched between the two layers of liquid crystal glass substrates.
SCXH`s “Shatter-resistant glass” released on September 19 is an iterative product of high-aluminum cover products. Among them, the latter belongs to soda-alumina-silicate glass, while the former is lithium-aluminum-silicate glass. The glass production materials have undergone great changes. Two alkali metal ions, sodium and lithium, are introduced.
Compared with the single-strength lithium-aluminum-silicate glass, the surface compressive stress is increased by about 1.2 times, the depth of the stress layer is 2 times, the bending strength is increased by 1.5 times, and the drop resistance height is increased by more than 5 times.
"After testing, the soda-alumina-silicate glass can reach 1.5-2 meters without breaking when dropped on 180g weight 180 mesh sandpaper with gravity acceleration. This will greatly extend the service life of mobile phones and other terminal products, and Improve consumer experience, and is expected to expand the scope of application of cover glass.
