Abstract
A pixel driving circuit, a driving method thereof, and a display panel are proposed. The pixel driving circuit includes a switching transistor connected between a gate of the driving transistor and the initialization voltage node and between the first electrode of the driving transistor. The active layer of the switching transistor includes an oxide semiconductor with a characteristics of low leakage current. The display quality is improved when the display panel is operated in the low-frequency driving mode for display.
