Abstract
A pixel drive circuit and a drive method thereof, a display panel, and a terminal device, which are applied to the field of terminal technologies. The pixel drive circuit includes a first reset module, a light-emitting control module, and a drive module, and both the first reset module and the light-emitting control module are connected to a light-emitting control signal terminal, where one of the first reset module and the light-emitting control module is turned on when 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 when the light-emitting control signal is at a low level. Therefore, by increasing the frequency of the light-emitting control signal to greater than 120 Hz, a problem of a phenomenon of frequent flickering on an image during low-brightness display may be improved.
