Pixel circuit driving method, pixel circuit and display panel

The embodiment of the invention discloses a pixel circuit driving method, a pixel circuit and a display panel. A data writing stage is divided into a first sub-stage and a second sub-stage, and different voltages are provided for a data voltage input end of the pixel circuit in the first sub-stage and the second sub-stage, so that the gate of the driving transistor can be quickly charged to a first voltage. The first voltage is greater than the difference between the target data voltage and the threshold voltage of the driving transistor, so that the driving transistor can be switched on whenthe gate voltage of the driving transistor is the first voltage, and the driving transistor can be kept in a switched-on state in the second sub-stage; writing of the target data voltage to the gate of the driving transistor is completed in a short time. The gate electrode of the driving transistor is rapidly charged to the first voltage in the first sub-stage, so that the data voltage writing speed is increased, the time
