The Glass for Smartphones – “Gorilla” vs “Dragontrail” vs Sapphire

The screen is no longer the most fragile part in a smartphone. This was made possible through the use of special coatings that protect the surface from all sorts of damages. What kind of glass is used in modern smartphones such as, say, Samsung smartphone, and what their differences are – these are the things we will try to find out.

Today, there are three leaders on the protective material market:
• Gorilla Glass by the American company Corning;
• Dragontrail from the Japanese industrial giant called Asahi Glass Company;
• Sapphire protective glass produced by the GT Advanced Technologies Corporation.

Gorilla Glass
No doubt, that that the most popular protective glass used in smartphones is Gorilla Glass. It began its development in the late 50s, but, in the telephone equipment, it was first used only in 2006. Then we saw the new generations of the innovative glasses, each of which was much stronger than its predecessor. As a result, today, most smartphones are equipped with Gorilla Glass screens.

The company Asahi Glass Co., Ltd. also did plenty of research in the field as well. It is a division of Mitsubishi, and most probably is the largest producer of glass. The material released by this concern appeared on the market later than “Gorilla Glass” but it already managed to enter into the arsenal of nearly 40 well-known brands. Initially Gorilla Glass was even inferior to Dragontrail in its characteristics, but its recent generations have proved to be more competitive, though.

Synthetic sapphire
Another popular glass is the so-called sapphire crystal manufactured by the company GT Advanced Technologies. It is known that sapphire is the second natural material in terms of strength, and therefore it can be scratched with a diamond and a sapphire itself only. Sapphire cannot be harmed even with quartz sand, which affects most of the modern screens. On the other hand, sapphire can be considered to be innovative material only conditionally. It is synthetic and produced by crystallizing aluminum oxide at high temperatures, and then it is cut and polished when hot. Nowadays, synthetic sapphire is more commonly used in high-end models of watches, and in addition, some modern cameras in smartphone phones are also equipped with this kind of glass.

A comparative characteristics of the synthetic glasses
The aforementioned glass types are about the same, yet each of them has a number of advantages and disadvantages. Thus, the last generation of Gorilla Glass resists shock better than the others, but it is easier to scratch and it has less elasticity in comparison with, for example, sapphire. At the same time synthetic sapphire is hardly vulnerable to abrasive, it has good fracture strength, but its cost is higher, which ultimately affects the final cost of a smartphone. In this context, we suggest you visit to compare phone prices and see how different types of glass used affect the smartphone price. As for Dragontrail, it is relatively inexpensive, but is inferior in strength to “Gorilla Glass” and the Sapphire.
