The invention provides a pixel driving circuit and a display substrate, and belongs to the technical field of display. The invention provides a pixel driving circuit. The pixel driving circuit comprises a driving sub-circuit, a data writing sub-circuit, a threshold compensation sub-circuit and a storage reset sub-circuit. Wherein the storage reset sub-circuit is connected with a first control signal line, and when a high-frequency signal is written into the first control signal line, the storage reset sub-circuit writes the high-frequency signal written into the first control signal line into the control end of the driving sub-circuit so as to reset the control end of the driving sub-circuit; when a direct current signal is written into the first control signal line, a data voltage signal written into the data writing sub-circuit can be stored. 本公开提供一种像素驱动电路以及显示基板，属于显示技术领域。本公开提供了一种的像素驱动电路，其包括：驱动子电路、数据写入子电路、阈值补偿子电路以及存储复位子电路。其中，存储复位子电路连接第一控制信号线，在第一控制信号线被写入高频信号时，存储复位子电路将第一控制信号线上所写入的高频信号写入驱动子电路的控制端，以对驱动子电路的控制端进行复
