Is the broken mobile phone screen an inner or outer screen?

Today's mobile phones are basically all-in-one, that is, the inner screen and the outer screen are fused together through glue, and the inner screen and the outer screen are separated like the mobile phone before last year, so there is basically no tool for maintenance.

The inner screen is the LCD of the mobile phone, and the outer screen is the touch screen. If a mobile phone is used for about a year, is it worth replacing because it is accidentally broken? Today's mobile phones are normally thousands of mobile phones, and if the inner screen is broken, it will probably cost hundreds of dollars to replace it, but the outer screen is about one or two hundred.

Therefore, the breakage of the mobile phone screen still depends on the inner screen or the outer screen, but for rich people, of course, it is better to change to a new machine, anyway, the current mobile phone is updated so quickly.

If you have a mobile phone of two or three thousand, because you accidentally broke the inner screen and the outer screen, but you want to continue to use it and don't want to go to the mobile phone store to change it, it is too expensive. Maybe you can change it yourself and buy a mobile phone's total screen online, that is, the inner screen and the outer screen are handled.

The phone screen is broken, is it worth changing?

Nowadays, many people change to a mobile phone in about a year or two, from an ordinary screen to the current full-view screen. The mobile phone screen of the full view screen accounts for about 98% of the mobile phone surface, and if it is accidentally broken, it will basically be broken, and the current mobile phone shatterproof technology is too low.

Is it worth replacing the broken screen of the iPhoneX mobile phone, now the iPhoneX** is about 6,000 yuan, and the iPhoneX screen is about 2,000 yuan, even if you change it yourself, you have to buy a total screen of 2,000 yuan. The labor cost is about one or two hundred, and if you change it yourself, you need to have this technology.

Most of the screens in ordinary mobile phone repair shops are non-original screens, and customers need to order to replace the original screens, and some repair shops and large repair shops will have accessories for the original screen.

For mobile phone repair personnel, the composition of mobile phones is divided into two parts from a macro perspective: external distribution and motherboard.

External: Except for the motherboard, it is called external. For example: screen, case, battery, cable, camera, etc. The external configuration is clear at a glance, even mobile phone users can distinguish it.

Motherboard: It is mainly composed of PCB board, resistor, capacitor, inductor, diode, transistor, field effect transistor, interface device (inline seat), sensor, integrated circuit (BGA chip) and other components. It is used to realize internal and external signal processing, as well as the control of all functions of the mobile phone, including display, signal, charging, power-on and other functions.

In a mobile phone, the leading role is the integrated circuit, that is, those BGA chips, each integrated circuit has different functions, knowing the integrated circuit on a motherboard, is the only way to learn and correct the maintenance of the mobile phone.

The original screen has no hardware impact (except for waterproof, light leakage, etc.), and it is not necessary to assemble the screen, such as the unresponsive touch screen, the color deviation of the display screen, etc.

There is a difference from the original:

1.The original screen is the screen of the mobile phone manufacturer that has been tested to perfectly adapt to the mobile phone, and the quality is ***, if there is a non-human quality problem, it can also be guaranteed;

2.The non-original screen is adapted by other manufacturers, and there may be imperfect adaptation, such as increased power consumption, insensitive touch screen, etc.;

3.It is easy to buy non-original bottles, and it is also much cheaper than the original screen.

How to tell if an Apple phone is the original screen:

1.Press the mobile phone screen with your hand, if you press it casually, the screen is not abnormal, then the screen is original, if there is colored light like the computer or computer screen, then it must not be the original;

2.Observe the color, if it's not the original screen, it's cooler, a bit like 3GS kind of screen, biased towards blue, and the original screen is obvious;

3.Looking at the front camera, the original screen can easily see the inside of the rest of the camera ruler, while the refurbished screen is blurry;

4.The first drop of water on the screen, if the water droplets are scattered, then it is not original, if the water droplets are three-dimensional, it is original.
