Abstract
A pixel driving circuit and a display panel are provided, and adopt a pixel driving circuit of 5T1C structure to effectively compensate the threshold voltage of the driving transistor in each pf the pixels. The pixel driving circuit can effectively reduce leakage power consumption of a pixel driving circuit when extracting a threshold voltage, thereby improving compensation accuracy of the pixel driving circuit.
