Abstract

A pixel circuit and its driving method, as well as a display device, are disclosed. The pixel circuit includes a driving circuit, a first compensation circuit, and a second compensation circuit. The first compensation circuit includes a first storage capacitor, with a first electrode of the first storage capacitor connected to the control terminal of the driving circuit, and a second electrode of the first storage capacitor connected to the first terminal of the driving circuit. The second compensation circuit includes a second storage capacitor and a first switching transistor. A first electrode of the second storage capacitor is connected to the first terminal of the driving circuit, a first electrode of the first switching transistor is connected to the second storage capacitor, and the gate electrode of the first switching transistor is configured to receive a second compensation control signal.
