Abstract
A pixel circuit and a driving method thereof, and a display panel including the same. The pixel circuit includes, a first module and a second driving circuit, the first driving circuit drives the light emitting circuit to emit light during a first period under control of a first scanning signal at the first scanning control terminal, and the second driving circuit drives the light emitting circuit to emit light during a second period under control of a second scanning signal at the second scanning control terminal, the first and the second period not overlapping with each other. A light emitting device is alternately driven to emit light by using two driving circuits, so that one driving circuit enters a recovery stage while the other driving circuit drives the light emitting device to emit light, and thus threshold voltage drift of driving transistor can be reduced, while lifespan thereof can be prolonged.
