Abstract
A pixel circuit, a driving method and a display device are provided. The pixel circuit includes: a data writing unit, a driving unit, a light emitting unit and an initialization unit. The initialization unit is configured to initialize a second node with an initialization voltage. The data writing unit is configured to set voltage of a first node to the voltage of a data signal and update voltage of the second node. The driving unit is configured to drive the light emitting unit to emit light according to a control signal. Due to the second node being initialized and compensated by the initialization unit, the storage capacitor leakage paths and the electric leakage of the storage capacitor during the light emitting stage are reduced, thus improving the quality of the displayed image.
