Classification: CPC G | IPC G

Claim 15:
16. 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 data write transistor, wherein the data write transistor is connected to a third node, and a first electrode of the drive transistor is connected to the third node;
at the valid frame, the data write transistor provides a data signal to the third node; and
at the invalid frame, the data write transistor provides an adjusting voltage to the third node; and
wherein the display frame in the first drive mode comprises a plurality of invalid frames, and the plurality of invalid frames comprise a first invalid frame and a second invalid frame, and wherein in a drive sequence, the first invalid frame is located between the valid frame and the second invalid frame, and the first invalid frame has a lower adjusting voltage than the second invalid frame.
