Abstract
The present disclosure discloses a pixel circuit, an array substrate, a display device and a pixel driving method, the pixel circuit including: a driving transistor, a light emitting device, a reset sub-circuit, a light emitting control sub-circuit, a compensation sub-circuit and a data writing sub-circuit, the compensation sub-circuit acquires a threshold voltage of the driving transistor and a turn-on voltage of the light emitting device in response to control of the second control signal and the third control signal, and writes a control voltage to a gate of the driving transistor in response to the first control signal, the control voltage is equal to a sum of the threshold voltage, the data voltage and the turn-on voltage, so that the driving current outputted by the driving transistor is independent of the threshold voltage of the driving transistor, and is positively correlated with the turn-on voltage of the light emitting device.
