Abstract
The present disclosure provides a GOA device and a gate drive circuit. The GOA device includes at least two GOA units in cascade. The present disclosure connects the input terminal of the pull-up control circuit to the start signal of the n−7-th stage, the control node (Qn) of the n-th GOA unit is thus pulled up to the first high potential and the bootstrap capacitor is charged. The control node (Qn) is charged 7 stages in advance, which resolves the technical problem of insufficient charging of the high-resolution high-refresh rate display panel in the related art.
