A pixel circuit and a driving method therefor, a display panel, and a display device, for use in increasing the service life of the pixel circuit. The pixel circuit comprises: a charger sub-circuit (1), a capacitor (CST), a first driver sub-circuit (2), and a second driver sub-circuit (3). A first terminal of the capacitor (CST) is connected to first terminals of the first driver sub-circuit (2) and of the second driver sub-circuit (3). A second terminal of the capacitor (CST) is connected to the charger sub-circuit (1). A second terminal of the first driver sub-circuit (2) is connected to a first light-emitting component (D1). A second terminal of the second driver sub-circuit (3) is connected to a second light-emitting component (D2). A driving current (I1) of the first driver sub-circuit (2) that flows into the first light-emitting component (D1) and a driving current (I2) of the second driver sub-circuit (3) that flows into the second light-emitting component (D2) are opposite in direction. The charger sub-circuit (1) is used for charging the capacitor (CST). When the capacitor (CST) is discharging, either the first driver sub-circuit (2) is allowed to drive the first light-emitting component (D1) into emitting a light, or the second driver sub-circuit (3) is allowed to drive the second light-emitting component (D2) into emitting a light. |
