Abstract
A pixel circuit, a method of driving a pixel circuit and a display panel. The pixel circuit includes: a drive circuit, a data writing circuit, a compensation circuit, and a light emitting element. The drive circuit includes a control terminal, a first terminal and a second terminal, and is configured to control a drive current flowing through the first terminal and the second terminal for driving the light emitting element to emit light. The data writing circuit is configured to write a data signal to a first terminal of the drive circuit in response to a first scanning signal. The compensation circuit stores a data signal written by the data writing circuit and compensates the drive circuit in response to a second scanning signal. A first terminal of the light emitting element receives a drive current, and a second terminal thereof is connected to a second voltage terminal.
