Abstract
The present invention provides a pixel circuit, a display substrate and a display panel. The pixel circuit comprises a power supply terminal; a control thin film transistor; a drive thin film transistor; a storage capacitor; a light-emitting device, the pixel circuit further comprises a voltage division control module and a voltage division capacitor, the voltage division control module is used for charging the storage capacitor in the pre-charging phase of the pixel circuit, so that voltage of the gate of the drive thin film transistor becomes a reference voltage, and the voltage division control module is capable of outputting a low level to the second end of the storage capacitor in the compensation phase of the pixel circuit. A first end of the voltage division capacitor is connected to the first end of the storage capacitor, a second end thereof is connected to the cathode of the light-emitting device.
