Claim 5:
6. The pixel driving circuit according to claim 1, wherein the data-writing sub-circuit comprises:
a first-data-write-control transistor, wherein a control terminal of the first-data-write-control transistor is coupled to a second scanning line, and an input and an output of the first-data-write-control transistor are coupled to the data voltage terminal and the input of the driving transistor, respectively; and
a second-data-write-control transistor, wherein a control terminal of the second-data-write-control transistor is coupled to the second scanning line, an input of the second-data-write-control transistor is coupled to a first control terminal of the driving transistor, and an output of the second-data-write-control transistor is coupled to the output of the driving transistor; in a writing process of the data voltage, the data voltage is written to the first control terminal of the driving transistor through the first-data-write-control transistor, the driving transistor and the second-data-write-control transistor.
