Abstract
Disclosed are a pixel drive circuit, a driving method, and a display panel. The pixel drive circuit includes a light-emitting element; a power supply line, including a high-potential power supply and a low-potential power supply, connected to the light-emitting element; a pulse amplitude modulation unit, including a first drive transistor connected to the light-emitting element and the power supply line; wherein a driving current with different amplitudes is provided to the light-emitting element according to a voltage applied to a gate of the first drive transistor; and a pulse width modulation unit, including a second drive transistor connected to the light-emitting element and the pulse amplitude modulation unit; wherein a duration of the driving current of the light-emitting element is controlled according to a voltage applied to a gate of the second drive transistor.
