1. A flicker debugging method for a display panel, comprising:
acquiring a plurality of display brightness data of the display panel in a preset time period;
processing the plurality of display brightness data to obtain a time-domain signal of the plurality of display brightness data, the time-domain signal being continuous in a time domain;
determining a flicker degree parameter of the display panel according to change rates of display brightness data in a plurality of first time periods in the time-domain signal of the plurality of display brightness data, wherein duration of each of the plurality of first time periods is determined according to visual persistence time of a human eye, and duration of the preset time period is greater than the duration of the each of the plurality of first time periods; and
determining whether to debug the display panel according to the flicker degree parameter.
