Claim 18:
19. A display device, wherein the display panel comprises:
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 in sequence, wherein m≥2;
at least two sub-bias stages have different durations.
