Disclosed is a pixel circuit arranged in a display substrate, which comprises a first driving mode and a second driving mode. Content displayed in the display substrate comprises multiple display frames. In the first driving mode and the second driving mode, the display frames comprise refresh frames. A signal of a second scanning line is the same as that of a third scanning line. The time of which the signal of the second scanning line is an active level signal comprises a first refresh time period, a second refresh time period and a third refresh time period, which sequentially occur at intervals. During the second refresh time period, a signal of a first scanning line is an inactive level signal. The voltage of a signal at a reset voltage end is a positive voltage, and the voltage of a signal at a first initial voltage end is a negative voltage.
