Provided are a display panel, a driving method thereof, and a display device. The display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes an amplitude modulation subcircuit and a pulse width modulation subcircuit. The amplitude modulation subcircuit is connected to a first data signal line. The pulse width modulation subcircuit is connected to a second data signal line. At least one of the first data signal line or the second data signal line is used to transmit a data signal and a bias adjustment signal.
