Abstract
Embodiments of the present disclosure provide a pixel circuitry, a drive method thereof, an array substrate and a display panel. The pixel circuitry includes circuits designated: drive CD, data write CDW, initialization CI, first light emission control CLEC1, first storage CS1, second storage CS2 and second light emission control CLEC2. CD connects to first through third nodes N1-N3 and provides drive current to a light emitting device. CDW connects to N1 and provides a data signal to CD according to a drive signal. CI provides an initialization signal to N2 according to a reset signal. CLEC1 provides a first voltage signal to N3 according to a first light emission control signal. CS1 and CS2 store a voltage difference between the first voltage signal terminal and N2, and N1 and N2, respectively. CLEC2 controls the drive current to the light emitting device according to a second light emission control signal.
