It is difficult to avoid damage to the touch glass. Even with careful treatment, the display gradually becomes covered with cracks and chips due to accidental impacts. The surface of the glass also breaks down due to friction. When the phone is in the same pocket with keys or any other hard object, its surface is scratched. Although some types of covers protect the screen well from minor mechanical impact, if the smartphone is dropped and hit hard, they are not able to keep the glass from shattering. To preserve the integrity and functionality of the display, you need to install a Gionee screen protector on your phone as soon as possible.
The protective glass is a multilayer product. Each layer has a specific function. Most shockproof glass for phones contains 5 layers: adhesive, restraining, protective, anti-glare, oleophobic. The adhesive layer is in contact with the smartphone screen. Thanks to it, the protective glass is securely fixed on the gadget. Silicone or glue can be used as the fixing material. The restraining layer prevents the safety glass from cracking and crumbling upon impact. The role of the restraining layer is played by a thin film coated with an optically pure adhesive composition. The film holds all parts of the glass in position when the impact force is applied to them.
The protective layer is the main one. It is made of tempered glass. Thanks to the tempering procedure and chemical treatment, the glass can withstand the significant physical stress that a phone can take when dropped. The anti-reflective layer makes the surface of the tempered glass roughened. Therefore, the light emanating from the smartphone screen freely penetrates through the glass, and the ambient light is trapped and scattered. Thanks to the anti-glare layer, the image on the display of the gadget is clearly visible even in sunny weather.
Oleophobic coating repels grease and dirt. Therefore, the surface of the protective glasses remains clean even with intensive use of the gadget. The top layer is formed from a mixture of silicone, alkylsilane, and solvent. Vapors of the mixture are deposited on an anti-reflective layer. Over time, the oleophobic coating wears off due to mechanical stress.
