PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL AND DISPLAY DEVICE

WIPO Patent Application WO/2020/248922

A1

A pixel circuit, comprising: a pixel driving circuit (1) connected to a gate line (Gate) and a data line (Data) and configured to generate a driving current (I) based on a data signal provided via the data line (Data) in response to a gate driving signal provided via the gate line (Gate), and output the driving current (I) by means of a current output end (OUT0) of the pixel driving circuit (1); and a shunt circuit (2) connected to the gate line (Gate) and a first control signal line (CL1) and configured to control ON/OFF between a first signal input end (IN1) and a first signal output end (OUT1) of the shunt circuit (2) in response to the gate driving signal provided via the gate line (Gate) and a first control signal provided via the first control signal line (CL1). The current output end (OUT0) of the pixel driving circuit (1) is connected to a first end of a light-emitting device (LED) and the first signal input end (IN1) of the shunt circuit (2), and the first signal output end (OUT1) of the shunt circuit (2) is connected to a pixel circuit to be charged.
