GOA circuit and a liquid crystal display
Abstract:
The invention disclosure a GOA circuit and a liquid crystal display. The GOA circuit including an electrical potential pull-down controlling circuit and a plurality of GOA sub circuits in cascade connection, the electrical potential pull-down controlling circuit comprising a first voltage limited transistor, a second filter transistor and a third transistor. The first voltage limited transistor, and the second filter transistor a reconnected in series and between the output terminal of the initial scanning signal, STV signal and the control terminal of the third transistor, the control terminal of the first voltage limited transistor and the first terminal of the third transistor is connected to the first power terminal and the second terminal of the third transistor is connected to the GOA sub circuit. By this design, the damage from the large static electricity to the GOA sub circuit can be avoided.
