1. A display panel, comprising:
a plurality of data signal lines arranged along a first direction and electrically connected to a plurality of pixel circuits,
wherein each of the plurality of pixel circuits comprises:
a driving module configured to generate a light-emitting driving current,
a data voltage writing module configured to transmit a signal transmitted by one of the plurality of data signal lines to an input terminal of the driving module; and
a threshold voltage capturing module,
wherein when the display panel displays one frame of at least one frame of an image, the display panel comprises a first phase and a second phase performed after the first phase, wherein the first phase comprises a data writing phase and a first light-emitting phase performed after the data writing phase, and the second phase comprises at least one adjusting phase and a second light-emitting phase performed after the at least one adjusting phase;
during the data writing phase, the data voltage writing module is turned on, and the one of the plurality of data signal lines is configured to transmit a data voltage to the driving module;
during each of the at least one adjusting phase, the data voltage writing module is turned on, and the one of the plurality of data signal lines is configured to transmit an adjusting voltage to the driving module; and when the display panel displays one frame of the at least one frame of the image, the adjusting voltage transmitted by the one of the plurality of data signal lines during the second phase corresponds to the data voltage transmitted by the one of the plurality of data signal lines during the first phase;
the threshold voltage capturing module is turned off during the at least one adjusting phase; and
the driving module comprises a driving transistor, the adjusting voltage is configured to reduce a difference between a bias state of the driving transistor during the second phase and a bias state of the driving transistor during the first phase.
