1. A display panel, comprising:
a pixel circuit and a light-emitting element,
wherein the pixel circuit comprises a light emitting control module and a drive module; the drive module comprises a drive transistor; the light emitting control module comprises a first light emitting control module and a second light emitting control module, the first light emitting control module is connected between a first power supply signal terminal and an input terminal of the drive module, and the second light emitting control module is connected between an output terminal of the drive module and the light-emitting element;
wherein a control terminal of the first light emitting control module is connected to a first light emitting control signal line to receive a first light emitting control signal;
wherein a control terminal of the second light emitting control module is connected to a second light emitting control signal line to receive a second light emitting control signal;
wherein a width of the first light emitting control signal line is larger than a width of the second light emitting control signal line; and
wherein a working process of the pixel circuit comprises a light emitting stage and a bias stage, wherein
in the light emitting stage, the first light emitting control module is on, and the second light emitting control module is on; and
in the bias stage, the first light emitting control module is on, and the second light emitting control module is off.
