Abstract
Provided display panel includes a pixel circuit and a light emitting element. The pixel circuit includes a drive module including a drive transistor, and a bias adjustment module configured to provide a bias adjustment signal to a first pole or a second pole of the drive transistor. Data refresh frequencies of the display panel include a first data refresh frequency Fand a second data refresh frequency F, where F>F. At the first data refresh frequency F, the bias adjustment signal is Vf, and at the second data refresh frequency F, the bias adjustment signal is Vf, where Vf≠Vf; or, at the first data refresh frequency F, a duration of a bias adjustment stage in one data refresh period is T, and at the second data refresh frequency F, a duration of a bias adjustment stage in one data refresh period is T, where T≠T
