ActiveCN109545145AImprove displayAvoid uneven display brightnessStatic indicating devicesEngineeringSignal lines
The invention discloses a pixel circuit, a driving method thereof, and a display device, and belongs to the technical field of display. The pixel circuit includes a compensation sub-circuit, a regulation sub-circuit, and a detection sub-circuit. Since the compensation sub-circuit can output a first power signal to a first node, the adjustment sub-circuit can adjust the potential of a second node according to the potential of the first node. Therefore, a drive current outputted to a light-emitting unit can be enabled to be independent of a threshold voltage of a driving transistor, i.e., achieving the internal compensation of the threshold voltage of the drive transistor. Since the detection sub-circuit can output the potential of the second node to a detection signal line connected to an external compensation circuit, the external compensation circuit can adjust the data signal voltage according to the voltage of the light-emitting unit, i.e., achieving external compensation of the threshold voltage of the driving transistor. The problem that the difference of the driving currents flowing through the respective light-emitting units due to the threshold voltage of the driving transistor causes the non-uniform display brightness of a display device is solved.
