Abstract
A pixel circuit comprises a drive sub-circuit (101), writing sub-circuit (102), reset sub-circuit (103), voltage stabilizing sub-circuit (104), storage sub-circuit (105) and light emitting element. The drive sub-circuit is configured to provide a driving current to the light emitting element under control of signals of a first node (N1) and a second node (N2); the writing sub-circuit is configured to write a signal from a data signal terminal (Data) to N2 under control of signal of a scan signal terminal (Gate); the storage sub-circuit is configured to store a voltage of N1; the voltage stabilizing sub-circuit is configured to stabilize a voltage of an anode terminal of light emitting element through signal of a voltage stabilizing signal terminal (V1); the reset sub-circuit is configured to reset anode terminal of light emitting element under control of signal of Gate and reset N1 under control of signal of a reset control signal terminal (Reset).
