Pixel Circuit and Driving Method Thereof, and Display Device

A driving method of a pixel circuit, the pixel circuit comprising:

• a light emitting element comprising an anode and a cathode that is electrically connected to a first voltage terminal;
• a control circuit electrically connected to the anode of the light emitting element and configured to be turned on or off in response to a control signal from a control line;
• a first switching circuit configured to be in a conductive state, in response to a first scan signal from a first scan line, to transmit a voltage from a data line;
• a driving circuit configured to drive the light emitting element to emit light under control of the voltage transmitted from the first switching circuit, the driving circuit comprising:
• a first transistor, of which a control terminal is electrically connected to the first switching circuit, a first terminal is electrically connected to a second voltage terminal, and a second terminal is electrically connected to the control circuit, and
• a capacitor, of which a first terminal is electrically connected to the second voltage terminal, and a second terminal is electrically connected to the first switching circuit;
• and
• a second switching circuit electrically connected to the data line, the second terminal of the first transistor and the control circuit, and configured to be in a conductive state, in response to a second scan signal from a second scan line, to stabilize a potential of the data line at a first fixed potential or a second fixed potential;
• wherein the driving method comprises:
• stabilizing, in a first stage, the potential of the data line at the first fixed potential that makes the light emitting element emit light;
• stabilizing, in a second stage, the potential of the data line at the second fixed potential that makes the first transistor be turned off;
