Did you ever experience a cracked screen on your phone? Its annoying and makes your phone loose its aesthetic appeal. As well as that, the device’s functionality is often limited.
Of course, our terminals are not exempt from damage to the display either. If this really happens, it is usually due to external violence. Through many years of experience, we are aware that our products are exposed to extreme requirements, especially when they are used in public places or in direct outdoor use. This is why we rely on the highest quality and the latest hardening and antireflection coating processes for our displays and built-in panes.
All glasses used in our devices are extra hardened by modern chemical processes in order to withstand the demanding application scenarios permanently. The scratch and impact resistance as well as the bending strength are enormously increased by the chemical hardening. The temperature resistance is also significantly improved as a result. Due to the chemically hardened glasses, thinner protective panes can be installed in front of the displays. This enables much better operation by touch gestures. Also a later printing or coating is possible without problems.
In addition to chemical hardening, there is also the possibility of thermal pre-stressing. The big advantage of thermally hardened glasses is the crumbling in case of breakage. This effect is mainly known from windows in front doors or cars. Hardening is achieved by changing the internal stress in the glass. The cut glass is heated to 600°C and suddenly cooled down. Since the core remains warm longer than the surface, a compressive stress is created there. On the other hand, tensile stress occurs in the core of the glass.
