Abstract

The present disclosure provides a pixel circuit, including: a pixel driving circuit coupled to a gate line and a data line and configured to generate a driving current based on a data signal provided by the data line in response to a gate driving signal provided by the gate line and output the driving current through a current output terminal; and a shunt circuit coupled to the gate line and a first control signal line, and configured to control connection/disconnection between a first signal input terminal and a first signal output terminal in response to the gate driving signal and a first control signal provided by the first control signal line. The current output terminal is coupled to a first terminal of a light emitting device and the first signal input terminal, and the first signal output terminal is coupled to a to-be-charged pixel circuit.
