The question you mentioned relates to the design and material selection of the iPhone. Here is my answer to it.
First, the iPhone's frame is made of aluminum or stainless steel instead of plastic. This is to provide higher structural strength and durability to ensure that the phone is not easily damaged in everyday use. Compared with plastic materials, aluminum alloy and stainless steel have more compression and tensile characteristics, which can better protect the internal parts of the phone.
Second, the iPhone's Glass screen uses a special reinforced glass material, such as Corning's Gorilla Glass. This reinforced glass has higher compression and scratch resistance, which reduces the risk of the screen shattering. However, glass still has a certain vulnerability, so users still need to be careful to handle and avoid violent impacts during use.
The iPhone is also designed with screen protection in mind. There is a small gap between the frame and the screen, so that when the phone falls, the frame can first contact the ground to reduce the force on the screen. At the same time, the iPhone's bezels are relatively wide, providing an extra layer of protection.
It is important to note that while the design and material choices of the iPhone are designed to reduce the risk of broken screens, they do not completely eliminate the possibility of broken screens. Since accidents such as falling and strong impact of the mobile phone are still possible, it is recommended that users use the mobile phone protective case or film in daily use to further increase the security of the screen.
All in all, the design of the iPhone's middle frame without a plastic holder is to provide higher structural strength and durability, and to reduce the risk of breaking the screen through a special material glass screen and a suitable design. However, users still need to exercise caution in daily use to protect the phone's screen from damage.
No, because it doesn't dissipate heat. The iPhone screen does not use a plastic holder, because the plastic holder has good sealing and cannot dissipate the heat in time, which will bring great harm to the screen and the phone battery. When using the iPhone in daily life, it must be used in accordance with the normal operation steps, otherwise it will bring losses.
Easy to break, because the plastic bracket, his hardness is very poor, but also can cause the mobile phone is relatively thick phenomenon, but also can make the touch is not very sensitive, so some mobile phone screens do not have this branch
In fact, the iPhone's frame is assembled by a piece of aluminum alloy blank through high-precision CNC processing, and its overall structure is more robust, without the need for plastic brackets to increase strength. In addition, its surface treatment adopts a special process to make its surface more flat and not easy to crack. Therefore, compared with other mobile phones, the risk of breaking the screen in the frame of the iPhone is less, and users can use it more confidently.
