Abstract
A pixel circuit includes a light emitting element, a first driving circuit, a second driving circuit, a first control circuit, a setting circuit, a first energy storage circuit, a second control circuit and a control data voltage writing-in circuit. The first control circuit controls to connect or disconnect the control end of the first driving circuit and the control end of the second driving circuit under the control of the potential of the first node. The second control circuit provides the second setting voltage to the control end of the first driving circuit, and connects or disconnects the control end of the first driving circuit and the connection node under the control of the control signal provided by the charging control end; the control data voltage writing-in circuit writes the control data voltage into the first node under the control of the first writing-in control signal.
