Hah, at last. I know many are looking for this feature in their smartphones. Smartphone screens are delicate as their manufacturing companies have to make sure the efficiency of their phones touch screen features. People are so tangled in smartphones these days that witnessing even a small scratch on their screen would make them shattered. I myself had to replace my phone screen 6 times in last 4 years. We already spend so much on our phones and moreover replacing a broken screen is very expensive. A survey by Motorola has revealed that 53% smartphone owners have their screen broken and at least 1/5th of these are using Smartphone with a broken screen. However, this problem is soon will be solved.
Japanese scientists discovered a glass material that is strong compared to many metals and can be used as a mobile phone screens. In their research, they found out that this glass is stronger than iron, copper or stainless steel. Also, this material is lighter than present day screens and so will reduce their phones weight to some extent which is also an advantage with this material.
What is this glass made of?
This new glass material will be an alloy of aluminum oxide and tantalum oxide. A special method called, “aerodynamic levitation” was used to build this material. This method is important because their previous methods were unsuccessful.
Durability of the material
In their reports to scientific Reports, they wrote and here I quote “Glasses with high elastic moduli have been in demand for many years because the thickness of such glasses can be reduced while maintaining its strength. …. Glass was colorless and transparent in visible region, and its refractive index nd was as high as 1.94”. According to their research specifications this glass can withstand a pressure of 9.1GPa while high carbon steel can only do a pressure of 4GPa.
Other technologies of protecting screen
Motorola’s Shattered shield
Recently Motorola and Verizon claimed that their combined version of Android phones- Turbo2 and Droid Maxx 2 has their screens so strong that they are offering a four-year warranty for their screen from the date of purchase. It has five layers of protection and each layer absorbs some of the strength they gain after their fall on the ground. They call this special protection layers as “shattered shield”. In case of any damage to the primary touch-sensitive layer, a second layer maintains functional operations. Picture quality will still be maintained by their flexible AMOLED display that absorbs the shocks during the impact. Recently, Motorola CEO, Osterloh has given a live demo of this product. He walked on the stage and dropped the phone twice making the audiences go ‘eww’ but screen damage was least.
Apple patents a sensor that rotates the phone during the fall
Recently Apple patented a technology that makes their phone to rotate in the air while falling and aligns itself such that the impact force gets reduced. It uses the phone internal vibration motor to flip the phone in the direction such that its center of gravity is changed while different sensors guide this fall interpreting the phone angle of decline.
With this new glass and technologies in hand, cracked screen will soon be a myth.
