1. A display panel, comprising a pixel circuit; wherein
the pixel circuit comprises a drive transistor and a boosting unit;
a first electrode of the drive transistor is connected to a pixel electrode;
a first terminal of the boosting unit is connected to a first data signal line, and the first data signal line is configured to receive a first data signal; and
a second terminal of the boosting unit is connected to a gate of the drive transistor, or a second terminal of the boosting unit is connected to a second electrode of the drive transistor;
wherein the boosting unit comprises a first transistor, a second transistor, a bootstrap capacitor and a reset transistor;
a first electrode of the reset transistor is connected to a reset signal line, and the reset signal line is configured to receive a reset signal;
a gate of the reset transistor is connected to a fourth scan signal line, and the fourth scan signal line is configured to receive a fourth scan signal; and
a second electrode of the reset transistor is electrically connected to one of the first electrode of the bootstrap capacitor or the second electrode of the bootstrap capacitor; and
wherein a working period of the pixel circuit comprises a reset stage and a data write stage in sequence;
in the reset stage, the fourth scan signal line provides the fourth scan signal to the gate of the reset transistor, and the fourth scan signal is an effective pulse for controlling the reset transistor to turn on to write the reset signal into the one of the first electrode of the bootstrap capacitor or the second electrode of the bootstrap capacitor; and
in the data write stage, the first data signal line provides the first data signal to the first terminal of the boosting unit.
