Abstract
There provides a liquid crystal panel including a GOA circuit and a driving method thereof, the GOA circuit including a plurality of single-level GOA circuit units that are cascaded, wherein each single-level GOA circuit unit includes a pull-down maintaining unit, the pull-down maintaining unit including a first transistor having a gate connected to a first node, a source connected to a present-level pre-charging node, and a drain connected to a low supply voltage wire; and a second transistor having a gate connected to an upper-level pre-charging node so as to receive a pre-charging signal from the upper-level pre-charging node and a drain connected to the low supply voltage wire, wherein the second transistor is configured to turn off the first transistor in response to an upper level pre-charging signal before the present-level pre-charging node is pre-charged.
