Abstract
Disclosed are a pixel circuit and a driving method thereof, an array substrate and a display device. The pixel circuit includes: a driving circuit, including a control terminal, a first terminal and a second terminal, and configured to control a driving current flowing through the first terminal and the second terminal for driving a light-emitting element to emit light; and input circuit, configured to transmit a reset voltage and a data signal in response to a first scan signal; a reset circuit, configured to apply the reset voltage to the control terminal in response to a second scan signal; a compensation circuit, configured to store the data signal and to electrically connect the control terminal with the second terminal in response to a third scan signal; and a data writing circuit, configured to apply the data signal to the compensation circuit in response to the third scan signal.
