How to solve iPhone X Screen Failure and Screen flicker ?

The iPhone x and previous Apple phone screens are different in material.
The screens before the 8th generation are all lcd, the screen is thicker, the display color is not bright enough.
iPhone X use Samsung's oled screen, which is very thin and can be curved or shaped.
But in fact, it is a distinction between internal and external screens.
If the touch fails, it will jump.
Basically, it can be judged that most of them are internal screen failures, and a small part is a motherboard problem.

The iPhone X screen fails with screen jitter, which is caused by two reasons:
1, the phone factory performance and quality problems, you can apply for after-sales replacement.
2. Caused by bumps or water in the process of use. No exemption is granted after sale.
The above two reasons are due to screen failure or motherboard chip failure, and there are ways to repair it. . . .

1. First analyze the three-layer structure of the iPhonex screen:

(1) The first floor is a tempered glass screen.
(2) The oled LCD screen + touch function layer of the face recognition sensor with face id inside.
(3) The bottom is the backlight layer.
The image displayed on the screen is formed by the oled LCD screen receiving signal and the internal screen illuminator. If the screen appears to jump, it is usually caused by a broken or shorted cable. Since the cable and the screen are welded together at the original high temperature, the general repair shop can only change the screen for you, and the cable cannot be replaced separately.
However, there is currently a technology on the market that can restore the cable by means of related machinery and equipment, high-temperature welding and repairing the cable, so that the screen can be restored to normal display. This requires a factory-level repair shop to do it.

2. Some chips on the motherboard are shorted or soldered, which will cause the screen to jump. For example, the cpu tip chip is soldered, the board line is broken, the display or the touch chip is shorted.

These situations need to be specifically checked by the universal meter to detect the specific faulty chip or line, and repair it by chip transplantation technology or flying line technology. This also requires factory level maintenance to do it.

Our Suggestion:

1: Go directly to Apple to apply for after-sales.
2: If you do fall or get into the water, you need to replace a new iPhone X Screen.
3: After the failure to replace the new mobile phone screen, there will be records in the background of the Apple mobile phone.
4: Generally speaking, the possibility of replacing the mobile phone screen is relatively high, but after the screen is replaced, the problem is still not solved, and it is definitely a motherboard problem, and the motherboard needs to be repaired.
