Abstract
Provided are a display panel, a driving method thereof, and a display device. A pixel circuit in the display panel includes a drive transistor, an initialization transistor, and an initialization signal line. An initialization signal terminal is electrically connected to a first terminal of the initialization transistor and the initialization signal line, a first terminal of the drive transistor is electrically connected to a power signal terminal, a second terminal of the drive transistor is electrically connected to a first terminal of a light-emitting element. The first drive mode corresponds to a first drive frequency F1 and a first initialization signal Vref1, the second drive mode corresponds to a second drive frequency F2 and a second initialization signal Vref2, and the third drive mode corresponds to a third drive frequency F3 and a third initialization signal Vref3, where F1>F2>F3, Vref1≠Vref2≠Vref3, and
