Claim 21:
22. The driving method according to claim 18, wherein the control circuit comprises:
a first transistor comprising a gate electrically connected to the one first control signal line, a first terminal electrically connected to the first node, and a second terminal electrically connected to the composite signal line; and
a second transistor comprising a gate and a second terminal that are electrically connected to the composite signal line, and a first terminal electrically connected to the first node;
wherein in the preparation period, said transmitting, by the control circuit, the second level provided by the composite signal line to the first node comprises: in the preparation period, providing, by the one first control signal line, the first level; providing, by the composite signal line, the second level; conducting the first transistor under the first level;
and transmitting the second level provided by the composite signal line to the first node through the conducted first transistor; and
in the pull-up period, said transmitting, by the control circuit, the first level provided by the composite signal line to the first node, to pull up the potential of the first node comprises: in the pull-up period, providing, by the one first control signal line, the second level; providing, by the composite signal line, the first level; conducting the second transistor under the first level; and transmitting the first level provided by the composite signal line to the first node via the conducted second transistor, to pull up a potential of the first node with the first level.
