Abstract
Provided display panel includes pixel circuit and light emitting element. The pixel circuit includes a drive module including a drive transistor, and a bias adjustment module to provide a bias adjustment signal to a first pole or a second pole of the drive transistor. Operation modes of the display panel include a first mode and a second mode, and a brightness level of the display panel in the first mode is greater than a brightness level of the display panel in the second mode. An operation process of the pixel circuit includes a data writing frame and a holding frame; the data writing frame and the holding frame in the first mode respectively correspond to a bias adjustment signal of Vs11 and Vs12; the data writing frame and the holding frame in the second mode respectively correspond to a bias adjustment signal of Vs21 and Vs22; where |Vs11−Vs12|=|Vs21−Vs22|.
