1. A display panel, comprising:
a plurality of sub-pixels each comprising a pixel circuit and a light-emitting element,
wherein the pixel circuit comprises an anode reset module;
wherein the plurality of sub-pixels comprises a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein the anode reset module of the red sub-pixel is configured to reset an anode of the light-emitting element of the red sub-pixel by using a first anode reset voltage, wherein the anode reset module of the blue sub-pixel is configured to reset an anode of the light-emitting element of the blue sub-pixel by using the first anode reset voltage, wherein the anode reset module of the green sub-pixel is configured to reset an anode of the light-emitting element of the green sub-pixel by using a second anode reset voltage; and
wherein the pixel circuit further comprises a driving transistor and a plurality of gate reset circuits, wherein the plurality of gate reset circuits correspond to each pixel of the plurality of sub-pixels, wherein gate reset circuits of the red sub-pixel, the green sub-pixel, and the blue sub-pixel are configured to respectively reset gates of the drive transistors of the red sub-pixel, the green sub-pixel, and the blue sub-pixel by using a same gate reset voltage.
