Abstract
A pixel circuit and a driving method thereof, and a display panel. The pixel circuit includes a reset circuit, a data writing circuit, a compensation circuit, and a driving circuit. The reset circuit is configured to apply a reset voltage to the first terminal of the light-emitting element to reset the first terminal of the light-emitting element; the data writing circuit is configured to write a data signal to the first terminal of the driving circuit; the compensation circuit is configured to write the reset voltage into the control terminal of the driving circuit when the reset circuit applies the reset voltage, and to write a compensation signal based on the data signal into the control terminal of the driving circuit when the data writing circuit writes the data signal; and the driving circuit is configured to control a driving current for driving the light-emitting element to emit light.
