Abstract:
The present disclosure provides a pixel driving circuit including a driving transistor, a capacitor and a light emitting device, and further includes: a first reset module; a data writing module; a threshold compensation module including a compensation transistor; a light emitting control module configured to disconnect the first power terminal from the first electrode of the driving transistor and disconnect the second electrode of the driving transistor from the light emitting device in the data writing phase and the reset phase; and to enable the first power terminal and the first electrode of the driving transistor to be electrically connected to each other and enable the second electrode of the driving transistor and the light emitting device to be electrically connected to each other in a light emitting phase; the compensation transistor is an oxide transistor, and the driving transistor is a low temperature poly-silicon transistor.
