Abstract
A pixel circuit, a driving method thereof and a display device are provided. The pixel circuit includes a drive circuit, a data writing circuit, a compensation-and-reset circuit, and a storage circuit. The drive circuit includes a control terminal, a first terminal and a second terminal, and is configured to control a driving current for driving a light-emitting element to emit light; the data writing circuit is configured to write a data signal to the control terminal of the drive circuit in response to a scanning signal; the compensation-and-reset circuit is configured to apply the reset voltage to the control terminal of the drive circuit in response to a compensation signal; the storage circuit is configured to store the data signal that is wrote and a threshold voltage, and to couple and adjust a voltage of the control terminal of the drive circuit.
