Abstract
A gate line driving circuit comprises a driving chip comprising first and second output ports, a LCD panel comprising first, second and third gate lines, a first switch and a second switch. Two terminals of the first gate line are respectively connected to the first output port and the control terminal of the first switch. Two terminals of the third gate line are respectively connected to the second output port and the control terminal of the second switch. The input terminal of the first switch electrically connects an operating voltage and the output terminal of the first switch electrically connects to the input terminal of the second switch. The output terminal of the second switch electrically connects a ground point, and one terminal of the second gate line is connected to between the output terminal of the first switch and the input terminal of the second switch.
