Claim 0:
1. A display panel, comprising:
a pixel circuit and a light-emitting element,
wherein the pixel circuit comprises a data write module, a drive module, a compensation module and a reset module;
wherein the drive module comprises a drive transistor;
wherein the data write module is connected to the drive transistor;
wherein the compensation module is connected between a gate of the drive transistor and the drain of the drive transistor;
wherein the reset module is connected to the drive transistor;
wherein the reset module is reused as a bias module;
wherein an operation of the pixel circuit comprises at least one reset stage and at least one bias stage,
during the reset stage, the reset module and the compensation module are on, and the reset signal terminal provides a reset signal for the gate of the drive transistor, during the bias stage, the reset module is on, the compensation module is off, and the reset signal terminal provides a bias signal for the drain of the drive transistor;
wherein the bias stage comprises m sub-bias stages, wherein m≥2;
at least two sub-bias stages have different durations.
