The edge processing technology of mobile phone tempered glass is directly related to the user's comfort when using the phone, and its importance cannot be underestimated.
First of all, one of the common edge processing methods is 2.5D arc edge processing. This processing is to grind the edge of the mobile phone tempered glass into a certain arc, so that it transitions more naturally and smoothly with the edge of the phone screen. When the user's finger slides on the edge of the screen, there will be no abrupt edges, which reduces the scratching feeling and greatly improves the smoothness of the operation. For example, when browsing the web and sliding the page left and right, the 2.5D arc edge allows the finger to slide over the edge easily without causing jamming or discomfort.
Secondly, there is 3D curved edge processing technology. It can make the tempered glass fit the curved screen of the mobile phone more closely, and visually achieve an effect that is almost indistinguishable from the naked screen. In terms of hand feel, the 3D curved edge can better fit the curved shape of the finger. When performing operations such as sliding inward from the edge of the screen to call up the multitasking bar, the finger can be evenly stressed, and the touch is soft and comfortable, as if directly touching the phone screen itself, which greatly enhances the pleasure of human-computer interaction.
Furthermore, the polishing process of the edge is crucial. The finely polished tempered glass edge has a very low surface roughness and is as smooth as a mirror. In this way, the friction when the finger slides on the edge is very small, and the hand feel is light and smooth. If the polishing is not fine enough, there may be slight unevenness on the edge, which will not only increase friction and cause a jerky feel, but may also scratch the finger skin after long-term use.
In addition, the edge treatment and the thickness of the tempered glass synergistically affect the hand feel. On the basis of ensuring a certain degree of protection, thinner tempered glass with good edge treatment can make users closer to the feeling of bare screen operation. Because the thin glass itself has little effect on touch sensitivity, coupled with comfortable edge treatment, users can hardly notice the existence of tempered glass when operating the phone, and it is more handy to operate.
Then, considering that the mobile phone may be used with a mobile phone case in daily use, the edge processing technology must also take into account the compatibility with the mobile phone case. Appropriate edge processing should ensure that the edge of the tempered glass will not be squeezed and warped or produce gaps after the mobile phone case is installed. Otherwise, the extrusion of the mobile phone case may cause the edge of the tempered glass to scratch the hand or affect the touch operation, thereby reducing the overall comfort of the hand feel. Therefore, when designing the edge processing solution, it is necessary to optimize it according to the body design of different mobile phone models and the types of common mobile phone cases.
Finally, as consumers' requirements for mobile phone usage experience continue to increase, mobile phone tempered glass edge processing technology is also continuing to innovate. For example, some new edge processing processes use special nano-coatings, which not only improve the smoothness of the edge, but also have anti-fingerprint and antibacterial functions, further improving user satisfaction, so that mobile phone tempered glass can not only ensure the safety of the mobile phone screen, but also bring users the ultimate hand feel enjoyment.
