Claim 13:
14. The method according to claim 13, wherein the display panel further comprises a second scanning driving circuit, wherein the second scanning driving circuit comprises second scanning driving unit groups that are cascaded, wherein each second scanning driving unit group of the second scanning driving unit groups comprises B second scanning driving units that are cascaded; and
in a case where the data writing transistor comprises a P-type transistor, said controlling the on-state current of the data writing transistor in the first pixel driving circuit to be smaller than the on-state current of the data writing transistor in the second pixel driving circuit comprises: controlling an effective level outputted by one of the second scanning driving units that is electrically connected to the first pixel driving circuit to be greater than an effective level outputted by one of the second scanning driving units that is electrically connected to the second pixel driving circuit; or in a case where the data writing transistor comprises an N-type transistor, said controlling the on-state current of the data writing transistor in the first pixel driving circuit to be smaller than the on-state current of the data writing transistor in the second pixel driving circuit comprises: controlling an effective level outputted by one of the second scanning driving units that is electrically connected to the first pixel driving circuit to be smaller than an effective level outputted by one of the second scanning driving units that is electrically connected to the second pixel driving circuit.
