1. A display panel, comprising:
a pixel circuit and a light emitting element;
wherein the pixel circuit comprises a drive module, and a bias adjustment module;
the drive module comprises a drive transistor; and
the bias adjustment module is configured to provide a bias adjustment signal to a first pole of the drive transistor or a second pole of the drive transistor;
wherein operation modes of the display panel comprise 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;
wherein the bias adjustment signal in the first mode is Vs1 and the bias adjustment signal in the second mode is Vs2, and wherein Vs1≠Vs2;
wherein a brightness level of the display panel comprises a first brightness level segment and a second brightness level segment, a brightness level value within the first brightness level segment is greater than a brightness level value within the second brightness level segment; and
wherein the bias adjustment signal within the first brightness level segment is unchanged, and the bias adjustment signal within the second brightness level segment is unchanged, and the bias adjustment signal within the first brightness level segment is not equal to the bias adjustment signal within the second brightness level segment.
