Abstract
The present disclosure provides a method for compensating a common voltage. The method for compensating a common voltage includes: generating a feedback signal by acquiring a real-time monitoring result of a feedback signal line on the common voltage, the feedback signal including a plurality of time periods, each of the time periods including a first sub-period in which the feedback signal is interfered by the periodic signal and a second sub-period in which the feedback signal is not interfered by the periodic signal; processing the feedback signal to eliminate distortion of the feedback signal caused by interference of the periodic signal in the first sub-period; and compensating for the common voltage according to the feedback signal.
