step one: detecting and analyzing the flicker phenomenon of the display screen: generating a detection period, dividing the detection period into a plurality of detection periods, acquiring a detection coefficient JC of the detection period, and judging whether scintillation detection in the detection period meets the requirement or not through the detection coefficient JC;
step two: analyzing display abnormal factors of a display screen, wherein the display abnormal factor analysis process comprises a magnetic field analysis process, a line analysis process, an electric quantity analysis process and a hardware analysis process, and prioritizing the magnetic field analysis process, the line analysis process, the electric quantity analysis process and the hardware analysis process through a priority order;
step three: analyzing the screen flicker characteristics in the detection period: marking a detection period in which screen flicker occurs in a detection period as an abnormal period, acquiring interval data and uniform data of the abnormal period, and generating a combination set and a priority sequence of the combination set through the interval data and the uniform data.
