1. A display panel comprising:
pixel circuits;
light-emitting elements; and
signal lines; wherein
for one of the pixel circuits:
the one of the pixel circuits is electrically connected to at least one of the light-emitting elements;
the one of the pixel circuits comprises a drive device, a first light-emitting control device and a second light-emitting control device;
the drive device is configured to drive the light-emitting element to emit light; and
the first light-emitting control device and the second light-emitting control device are configured to jointly control a light-emitting duration of the light-emitting element;
the signal lines comprise a first light-emitting control signal line and a second light-emitting control signal line, wherein the first light-emitting control signal line extends in a first direction parallel to a plane where the display panel is located, and the first light-emitting control signal line is connected with a first plurality of pixel circuits arranged along the first direction and is connected to the first light-emitting control devices in the first plurality of pixel circuits; the second light-emitting control signal line extends in a second direction parallel to the plane where the display panel is located, and the second light-emitting control signal line is connected with a second plurality of pixel circuits arranged along the second direction and is connected to the second light-emitting control devices in the second plurality of pixel circuits, wherein the first direction intersects with the second direction.
