Abstract
A pixel circuit, a driving method and a display, comprising: a compensation circuit () being electrically connected to a driving circuit () via a first node (N1); an external power supply (ELVDD), the driving circuit () and a light-emitting diode (EL4) being connected in series; a capacitor (C3) being located between the first node (N1) and the external power supply (ELVDD), wherein the compensation circuit () is used for setting the voltage of the first node (N1) to a first voltage (V+V) by means of a compensation transistor; the capacitor (C3) is used for maintaining the voltage of the first node (N1) as the first voltage (V+V); the driving circuit () externally connects a first control signal (En) to generate a driving current (IEL4) to drive the light-emitting diode (EL4) to emit light; and a driving transistor in the driving circuit () and the compensation transistor are common-gate transistors.
