1. A pixel drive circuit, configured to drive a light-emitting device to emit light, the pixel drive circuit comprising:
a first reset module respectively connected to a light-emitting control signal terminal, a first initialization signal terminal, and a first terminal of the light-emitting device, wherein the first reset module is configured to be turned on under control of a light-emitting control signal provided at the light-emitting control signal terminal, and to reset the first terminal of the light-emitting device through a first initialization signal provided at the first initialization signal terminal;
a drive module; and
a light-emitting control module respectively connected to the light-emitting control signal terminal, the drive module, and the first terminal of the light-emitting device, wherein the light-emitting control module is configured to be turned on under control of the light-emitting control signal provided at the light-emitting control signal terminal, and to drive the light-emitting device through the drive module to emit light,
wherein one of the first reset module and the light-emitting control module is turned on in a case that the light-emitting control signal is at a high level, and the other of the first reset module and the light-emitting control module is turned on in a case that the light-emitting control signal is at a low level, and
wherein a frequency of the light-emitting control signal is greater than 120 Hertz (Hz).
