A small tempered glass screen protector for mobile phone is now standard for smart phones. For those smart phones that cost a lot, the presence of the empered glass screen protector is even more important. There are various types of mobile phone tempered glass screen protectors on the market, but the prices vary greatly from low to high. Many people have questions: why are the prices of tempered glass screen protectors so different?
The tempered glass screen protector material is made of different brands. A good tempered glass screen protector should be so that the naked eye cannot distinguish whether there is a screen protector. The main difference between the two is the light transmittance, the mobile phone screen protector with poor light transmittance can harm the eyes. The transmittance of high-quality mobile phone screen protector is about 95%, while the low-quality one is below 80%.
The processing flow is the production flow of the mobile phone tempered glass screen protector. The high-quality tempered glass screen protector is processed by layers of machines and manually inspected. Only good machine processing can ensure the quality of the tempered glass screen protector of the mobile phone and the matching degree with the mobile phone. The fit of the tempered glass screen protector will affect the feel of the mobile phone. A perfectly fitted mobile phone screen protector can cover more of the edge of the screen, and the edge of the hand will not be easily touched when the screen is moved from the side. This mobile phone tempered glass screen protector processing machine accounts for a large part of the cost.
For glass screen protetor, the core is AB double-sided tape technology. What is AB glue? Tempered glass screen protector is not electrostatically attached to the phone screen like ordinary plastic protective film. It needs to be attached to the inner layer of the glass film with a thin layer of flexible double-sided tape. This thin layer of flexible double-sided tape is called AB glue. The quality of AB glue directly determines the bonding effect and exhaust effect of the tempered glass screen protector.
