Pixel circuit and driving method therefor, and display device

A driving method of a pixel circuit, configured to drive the pixel circuit according to claim 14, the driving method comprising:

• time of a frame sequentially including a pre-charge period, a compensation period and a light-emitting period;
• in the pre-charge period, turning on the data writing and compensation sub-circuit under control of the first control signal terminal, and transmitting, by the data writing and compensation sub-circuit, a data signal from the data voltage terminal to the driving sub-circuit, and turning on the light-emitting control sub-circuit under control of the second control signal terminal, and transmitting, by the light-emitting control sub-circuit, a first voltage signal from the first voltage terminal to the driving sub-circuit, to pre-charge the driving sub-circuit;
• in the compensation period, turning on the data writing and compensation sub-circuit under the control of the first control signal terminal, and compensating, by the data writing and compensation sub-circuit, a threshold voltage of the driving sub-circuit;
• and
• in the light-emitting period, turning on the light-emitting control sub-circuit under the control of the second control signal terminal, and transmitting, by the light-emitting control sub-circuit, the first voltage signal from the first voltage terminal and a second voltage signal from the second voltage terminal to the driving sub-circuit, and emitting, by the light-emitting sub-circuit, light under driving of a driving signal output by the driving sub-circuit and a third voltage signal from the third voltage terminal.
