Abstract
Provided are a display panel, a driving method thereof, and a display device. The display panel includes pixel circuits and light-emitting elements. A pixel circuit includes an amplitude modulation circuit and a pulse width modulation circuit. The amplitude modulation circuit includes an amplitude driving sub-module and an amplitude reset sub-module. The amplitude reset sub-module is configured to transmit a first reset signal to a control terminal of the amplitude driving sub-module. The pulse width modulation circuit includes a pulse width driving sub-module and a pulse width reset sub-module. The pulse width reset sub-module is configured to transmit a second reset signal to a control terminal of the pulse width driving sub-module. The voltage value of the first reset signal is Vref1. The voltage value of the second reset signal is Vref2. Vref1≠Vref2.
