Method and apparatus for adjusting signal frequency, display device and storage medium

An apparatus for adjusting a signal frequency, comprising:

• a first acquisition circuit, configured to acquire a clock signal output by a clock signal generator;
• determine a reference duration based on a frequency of the clock signal;
• and acquire a first number of times of outputting a reference signal at an active level within the reference duration, wherein a correlation between a frequency of the reference signal and temperature is less than a reference correlation threshold, the reference duration is negatively correlated with the frequency of the clock signal, a correlation between the frequency of the clock signal and the temperature is greater than the reference correlation threshold, and a drive signal for driving a display device to display an image is generated based on the clock signal;
• a second acquisition circuit, configured to acquire a target difference value between the first number of times and a reference number of times, wherein the reference number of times is a number of times of outputting the reference signal at the active level within the reference duration determined based on a reference frequency when the frequency of the clock signal is equal to the reference frequency;
• and determine an adjustment value corresponding to the target difference value as the target adjustment value based on a corresponding relationship between a difference value of the number of times and the adjustment value;
• and
• a control circuit, configured to control and adjust the frequency of the output clock signal based on the target adjustment value.
