Abstract
A pixel circuit and a driving method thereof, and a display device are disclosed. The pixel circuit includes: an initialization sub-circuit, configured to initialize a drive sub-circuit; a data write and compensation sub-circuit, configured to perform threshold voltage compensation on the drive sub-circuit; the drive sub-circuit, configured to output a signal of a second voltage terminal to a light-emitting sub-circuit; the light-emitting sub-circuit, configured to under control of the enable signal terminal input a signal of a first voltage terminal to the drive sub-circuit to control the drive sub-circuit to be turned on, and emit light under control of the enable signal terminal and a third voltage terminal; a leakage-current eliminating sub-circuit, configured to under the control of the enable signal terminal cause the initialization sub-circuit to output no signal to an initial voltage terminal when the initialization sub-circuit is in a turn-off state.
