Abstract: The present disclosure relates to the OLED display technology. There are provided a pixel circuit, a driving circuit, an array substrate and a display device, which are supplied with the voltage by the light emitting operation voltage when the pixel circuit enters the light emitting stage, by inputting an inverse signal synchronized with the pre-charging control voltage at the input terminal of the light emitting operation voltage to ensure a stable output of the current by the circuit at the light emitting stage. Also, it does not require an arrangement of an external voltage input terminal which will affect the aperture ratio, thereby increasing the aperture ratio of the OLED employing the current-driven pixel circuit while ensuring the stable output of the current by the current-driven circuit, and thus increasing the lifetime of the OLED employing the current-driven pixel circuit.
