Abstract
A pixel circuit and a driving method thereof and a display device are disclosed. The pixel circuit includes a switch circuit, a driver circuit, a compensation circuit, a reset circuit and a light emitting element. The driver circuit includes a control terminal, a first terminal and a second terminal and is configured to control a driving current, which runs through the first terminal and the second terminal; the switch circuit is configured to write a data signal to the control terminal in response to a scan signal; the compensation circuit is configured to store the data signal that is written in and electrically connect the control terminal and the second terminal in response to the scan signal; the reset circuit is configured to apply a reset voltage to the compensation circuit in response to a reset signal and electrically connect the control terminal and the first terminal.
