What is flicker phenomenon of LCD screen?

Flicker phenomenon is that the LCD screen will flicker, but it is not a special visual effect, but because the gray scale of the display screen changes slightly each time the screen is updated, which makes people feel that the screen screen is flickering. This is most likely to happen by using frame-by-frame inversion of polarity. Because the whole picture of frame-by-frame inversion is the same polarity, when the picture is positive this time, it will become negative next time. If there is a little error in common voltage, the same gray-scale voltage of positive and negative polarity will be different. Of course, the feeling of gray scale is different. In the case of constantly switching pictures, the Flicker phenomenon of the display screen will appear because the positive and negative polarity pictures appear alternately. And the polarity transformation of other panels, although there will also be this Flicker phenomenon, but because unlike frame-by-frame inversion is the whole picture to change polarity at the same time, there is only one row or column, or even a point to change polarity, in terms of the feeling of the human eye, it will not be obvious.
