1. A luminance compensation method, comprising steps of:
detecting whether a frequency variation pattern of a first frame queue satisfies a condition of luminance compensation, wherein the first frame queue comprises a plurality of consecutive frames;
if yes, turning on a luminance compensation module, wherein the luminance compensation module is configured to perform the luminance compensation on at least part of the consecutive frames in the first frame queue; and
if no, turning off the luminance compensation module;
wherein the step of detecting whether the frequency variation pattern of the first frame queue satisfies the condition of the luminance compensation further comprises a step of:
detecting whether the frequency variation pattern of the first frame queue is a first pattern;
wherein under the first pattern, a frequency of the plurality of consecutive frames in the first frame queue continuously alternates at least twice between a first frequency and a second frequency, an absolute value of a difference between the first frequency and the second frequency is greater than or equal to a first preset threshold, and the condition of the luminance compensation comprises the first pattern.
