Patent attributes
A GOA circuit is disclosed. The circuit includes multiple cascaded GOA units, wherein the nth stage GOA unit charges the nth horizontal scanning line, and the nth stage GOA unit includes: a pull-up control circuit, a pull-up circuit, a voltage stabilization circuit, a pull-down circuit, a first pull-down maintaining circuit and a second pull-down maintaining circuit; a pull-up control circuit for outputting a pull-up control signal Q(n); and a pull-up circuit for outputting an nth stage transmission signal ST(n) and the nth stage scan driving signal G(n); the voltage stabilization circuit for maintain the stability of the Q(n) at low voltage level; the pull-down circuit makes the Q(n) and G(n) to be at an off state; the pull-down maintaining circuit and the second pull-down maintaining circuit alternately operate to maintain Q(n) and G(n) at the off state. A liquid crystal display device having the above GOA circuit is also disclosed.
