Abstract
A display panel includes pixel circuits and light-emitting elements. A driving module in a pixel circuit is configured to provide a driving current for a light-emitting element in a light emission stage. A bias adjustment module is configured to provide a bias adjustment signal for a driving transistor of the driving module in a bias adjustment stage. A first non-light emission stage includes the bias adjustment stage. In the same first non-light emission stage, time between an end moment of the bias adjustment stage and an end moment of the first non-light emission stage is a bias maintaining stage. The brightness of the display panel in the first mode is different from that in the second mode. At least one of a duration of the bias adjustment stage and a duration of the bias maintaining stage in the first mode is different from the corresponding one in the second mode.
