Summary:The invention relates to a pixel driving circuit voltage compensation method, a voltage compensation circuit and a display panel. The method comprises the steps of when resetting of a pixel driving circuit is completed, acquiring gate voltage and source voltage of a corresponding driving TFT on the pixel driving circuit and collecting the voltage difference between the two ends of a resistor connected to a sensing line of the pixel driving circuit; obtaining a compensation voltage according to the grid voltage, the source voltage, the voltage difference, the resistance value of the resistor, the threshold voltage of the driving TFT and the initial mobility of the pixel driving circuit; and writing the compensation voltage into a corresponding data line on the pixel driving circuit. The voltage difference between the two ends of the resistor connected to the sensing line is collected, and the compensation voltage of the pixel driving circuit is obtained based on the voltage difference,so that the accuracy of t
