Claim 14:
15. The method according to claim 14, wherein
the B second scanning driving units in one second scanning driving unit group of second scanning driving unit groups comprise an m-th stage second scanning driving unit and an n-th stage second scanning driving unit, wherein an output terminal of the m-th stage second scanning driving unit is electrically connected to the data writing control terminal of the first pixel driving circuit, and an output terminal of the n-th stage second scanning driving unit is electrically connected to the data writing control terminal of the second pixel driving circuit, where m and n are both integers, and 1≤m<n≤B;
the B second scanning driving units comprise a clock terminal of the m-th stage second scanning driving unit and a clock terminal of the n-th stage second scanning driving unit, and the display panel further comprises B types of clock signal lines, wherein the B types of clock signal lines comprise an m-th type clock signal line and an n-th type clock signal line, wherein the m-th type clock signal line is electrically connected to the clock terminal of the m-th stage second scanning driving unit, and the n-th type clock signal line is electrically connected to the clock terminal of the n-th stage second scanning driving unit; and
in the case where the data writing transistor comprises the P-type transistor, said controlling the effective level outputted by the one of the second scanning driving units that is electrically connected to the first pixel driving circuit to be greater than the effective level outputted by the one of the second scanning driving units that is electrically connected to the second pixel driving circuit comprises: controlling an effective level transmitted by the m-th type clock signal line to be greater than an effective level transmitted by the n-th type clock signal line; and
in the case where the data writing transistor comprises the N-type transistor, controlling the effective level outputted by the one of the second scanning driving units that is electrically connected to the first pixel driving circuit to be smaller than the effective level outputted by the one of the second scanning driving units that is electrically connected to the second pixel driving circuit comprises: controlling an effective level transmitted by the m-th type clock signal line to be smaller than tan effective level transmitted by the n-th type clock signal line.
