摘要
Provided is a pixel circuit. The pixel circuit comprises a driving transistor and a light-emitting element both coupled in series between a first level end and a second level end, and comprises a second transistor, a third transistor, a fourth transistor, a first capacitor and a second capacitor. The second capacitor is coupled between a control electrode of the driving transistor and a second end of the light-emitting element. A threshold voltage is stored by the first capacitor, so that threshold voltage compensation for the driving transistor and the light-emitting element is implemented, and therefore the non-uniformity of the display of the pixel circuit is compensated. Also provided is a display device, wherein a first control line and a light-emitting control line are both global lines. Also disclosed is a pixel circuit driving method.
