Abstract

A method for adjusting the signal frequency includes: acquiring a first number of times of outputting a reference signal at an active level within a 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 a frequency of a clock signal, a correlation between a frequency of a clock signal and 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; acquiring a target adjustment value based on the first number of times if the first number of times is different from a reference number of times; and controlling and adjusting the frequency of the output clock signal based on the target adjustment value.
