Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 11:
12. A display panel, comprising:
a light-emitting element; and
a pixel drive circuit electrically connected to the light-emitting element,
wherein the pixel drive circuit comprises a drive transistor and a first reset module, the first reset module is connected to a first node and configured to provide a first reset voltage to the first node, and the light-emitting element is connected to the first node;
wherein a working mode of the display panel comprises a first drive mode, a display frame in the first drive mode comprises a valid frame and an invalid frame, and in the first drive mode, a first reset voltage for the valid frame is different from a first reset voltage for the invalid frame;
wherein the pixel drive circuit further comprises a second reset module, wherein the second reset module is connected to a second node and configured to provide a second reset voltage to the second node, and a gate of the drive transistor is connected to the second node; and
wherein the working mode of the display panel further comprises a second drive mode,
wherein a display frame in the second drive mode comprises a valid frame, the valid frame in the second drive mode has a higher frequency than the valid frame in the first drive mode, and a second reset voltage for the valid frame in the first drive mode is lower than a second reset voltage for the valid frame in the second drive mode.
