What is the reason for cell phone screen flicker

The reason for cell phone screen flicker; voltage instability caused by the screen drifting back and forth, software and system conflict problems caused.

1, cell phone screen, also known as the display, used to display images and colors. Referring to the screen color is essentially the concept of color scale. The color gradient is the index standard that indicates the brightness of the cell phone display, which is usually referred to as the color index.

2, voltage stability is the power system in the rated operating conditions and suffered a perturbation after all the buses in the system are continuously maintain an acceptable voltage ability. Voltage is what drives the directional movement of charge to form current. Current is also able to flow in a wire because there is a difference between a high potential and a low potential in the current.

3, caused by software and system conflict problems, is a possible conflict in programs when two or more software are running at the same time, causing one or both of them to fail to work properly.


Software conflicts come in many forms, but they always fall into two main categories: unintentional software conflicts and malicious software conflicts. For example; the same kind of software, installed more, the most likely to produce conflict, two similar functions of the software, it is best to install only one, the other uninstalled. Because, “like repels like, like attracts like”.
