Abstract
The present application provides a pixel driving circuit, a control method thereof, and a display device, which relates to the technical field of display. The pixel driving circuit is configured to drive a light emitting diode to emit light at different refresh rates, and includes: a first control module, a second control module, a compensation module, a refresh module, a first reset module, a first light emitting control module, a driving module, and a second light emitting control module. By holding potentials of a first node and a second node, the pixel driving circuit according to the present application may operate at different refresh rates, and the problem of insufficient Vth capture time is effectively solved.
