Abstract
A pixel circuit, a driving method, and a display device are provided. The pixel circuit includes: a signal input subcircuit, a threshold compensation subcircuit, a light-emitting control subcircuit, a drive transistor, a light-emitting device. The signal input subcircuit writes a voltage at a data signal end, a voltage at a reference voltage signal end, and a threshold voltage of the drive transistor into a gate thereof according to signals of first, second, and third control signal ends. The threshold compensation subcircuit turns on a gate of the drive transistor and a drain thereof under the control of a signal of a reset signal end. The light-emitting control subcircuit turns on a first power supply end and the drive transistor, and turns on the drive transistor and the light-emitting device under the control of a signal of a first light-emitting control end and a signal of a second light-emitting control end.
