Pixel circuit, driving method thereof and display device

A pixel circuit, comprising:

• a driving circuit, a data writing-in circuit and a reset circuit, wherein
• the data writing-in circuit is respectively coupled to a first scan line, a data line and a second end of the driving circuit, and is configured to control to connect the data line and the second end of the driving circuit under the control of a first scan signal provided by the first scan line;
• the reset circuit is respectively coupled to a third scan line, a reset voltage line and the second end of the driving circuit, and is configured to control to connect the reset voltage line and the second end of the driving circuit under the control of a third scan signal provided by the third scan line;
• or, the reset circuit is coupled to the third scan line, the reset voltage line and a first end of the driving circuit, is configured to control to connect the reset voltage line and the first end of the driving circuit under the control of the third scan signal;
• the driving circuit is configured to control to connect the first end of the driving circuit and the second end of the driving circuit under the control of a potential of a control end of the driving circuit.
