What is the reason for the mobile phone flashing screen and how to solve it?

There are software problems, hardware problems and battery problems for the reasons of mobile phone flashing, and the solutions are as follows:

1. Software problem: The mobile phone system or application program is abnormal, causing the screen to flicker. Solution: If it is a system problem, you can try to upgrade the system version.

2. Hardware problem: The screen of the mobile phone or other hardware fails, which causes the screen to flicker. Solution: Try to restart the phone and see if it can solve the problem.

3. Battery problem: the battery is insufficient or aging, causing the screen to flicker. Solution: If it is a battery problem, consider replacing the battery.

Mobile phone screen classification

According to the material of the screen, the mainstream screens of smart phones can be divided into two categories. One is LCD (abbreviation of liquid crystal display), that is, liquid crystal display, such as TFT, s LCD screen, etc. The other is organic light-emitting diode (short for organic light-emitting diode), that is, organic light-emitting diode, such as AMOLED series screen. The most fundamental difference between LCD and organic light-emitting diode is that organic light-emitting diode is self-luminous, while LCD needs backlight illumination to display.

According to the driving mode of screen display technology, it can be divided into passive matrix and active matrix. The difference between passive matrix and active matrix lies in the driving mode of current. When an external current passes, the arrangement of liquid crystals will change. After the current stops, if the liquid crystal arrangement does not return to its original position (memory), it is called active matrix. Once the current disappears, it will return to its original position and must be recharged before it can be arranged. This is the so-called passive matrix.
