Abstract
A pixel driving circuit, a driving method thereof and a display panel are provided. The pixel driving circuit includes a driving transistor, a capacitor having two terminals connected to a first power terminal and a gate electrode of the driving transistor, and a light emitting device. The pixel driving circuit includes: a reset module; a data writing module; a threshold compensation module including a compensation transistor configured to electrically connect second and gate electrodes of the driving transistor together in the data writing phase; a light emitting control module including a first gating transistor configured to electrically connect the second electrode of the driving transistor and the light emitting device in the reset phase and disconnect the second electrode from the light emitting device in the data writing phase. The compensation transistor and the first gating transistor are oxide transistors, and the driving transistor is a low-temperature polysilicon transistor.
