1. A display panel, comprising: a light-emitting element and a pixel circuit electrically connected to the light-emitting element, wherein
the pixel circuit comprises a drive transistor and an initialization transistor, wherein a first terminal of the initialization transistor is electrically connected to an initialization signal terminal, a second terminal of the initialization transistor is electrically connected to a gate of the drive transistor, a first terminal of the drive transistor is electrically connected to a power signal terminal, and a second terminal of the drive transistor is electrically connected to a first terminal of the light-emitting element;
the display panel further comprises an initialization signal line, wherein the initialization signal line is electrically connected to the initialization signal terminal and configured to transmit an initialization signal to the initialization signal terminal; and
drive modes of the display panel comprise at least a first drive mode, a second drive mode, and a third drive mode, wherein 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, wherein F1>F2>F3, Vref1≠Vref2≠Vref3, and
