Abstract:
A pixel circuit, a driving method and a display device having the pixel circuit are disclosed, wherein the pixel circuit comprises a compensation unit, a driving unit, a light emitting unit, a capacitor, an initialization unit and an external power supply and the driving method comprises a first initialization stage, a second initialization stage, a data writing stage and a light emitting stage.

Claim (Index 7):
A method for driving a pixel circuit, the steps of the method comprising:\n a first initialization stage including: turning on a second initialization transistor, configured to initialize a light emitting unit with an initialization voltage, by a third scanning signal; turning off a compensation unit by a first scanning signal; turning off a driving unit by a first control signal; and turning off a first initialization transistor by a second scanning signal; a second initialization stage including: turning on the first initialization transistor, configured to initialize the light emitting unit with the initialization voltage, by the second scanning signal; turning off the compensation unit by the first scanning signal; turning off the driving unit by the first control signal; and turning off the second initialization transistor by a third scanning signal; a data writing stage including: turning on the compensation unit, configured to set a voltage on a first node at a first voltage, by the first scanning signal; turning off the driving unit by the first control signal such that the light emitting unit does not emit light; turning off the first initialization transistor by the second scanning signal; and holding the voltage on the first node at the first voltage by a capacitor in a charging state, wherein the first voltage includes a voltage having a compensation voltage, generated by a compensation transistor in a compensation unit, and the voltage of the data signal; and a light emitting stage including: turning off the compensation unit by the first scanning signal; turning off the first initialization transistor by the second scanning signal; turning off the second initialization transistor by the third scanning signal; and turning on the driving unit, configured to generate a driving current which corresponds to the first voltage, an external power supply and a threshold voltage of a driving transistor in the driving unit, to drive the light emitting unit to emit light, by the first control signal, wherein the capacitor is configured to be in a holding state.
