Abstract
A 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, and the amplitude modulation subcircuit and the pulse width modulation subcircuit each includes a drive transistor. A working process of at least one of the amplitude modulation subcircuit or the pulse width modulation subcircuit includes a bias stage. A bias adjustment signal is provided to the drive transistor during the bias stage, and the bias adjustment signal is configured to adjust the bias state of the drive transistor.
