Abstract: Disclosed are a gate driving circuit and a driving method thereof, and a display device using the driving circuit. In the gate driving circuit, a Qn node in a nth-stage circuit is precharged when a Qn−1 node output signal in a previous-stage driving circuit and a Qn+1 node output signal in a next-stage driving circuit are both at high levels, and thus stability of a Gn output end in the nth-stage circuit can be greatly improved. Meanwhile, a first transistor and a second transistor are connected in series, and a third transistor and a fourth transistor are connected in series.

Abstract: A display panel includes a plurality of scan lines and connection lines. The plurality of scan lines are spaced from each other. The connection lines are connected to end portions of the plurality of scan lines. The connection lines are formed of intrinsic silicon. By having the connection lines that are formed of intrinsic silicon connected with the end portions of all the scan lines, due to intrinsic silicon being almost electrically non-conductive, this does not affect stage by stage activation of the scan lines and provides a way of power consumption by large resistivity of intrinsic silicon for preventing static electricity on end portions of the scan lines thereby overcoming the issue of static electricity being easily caused on the end portions of the scan lines and thus enhancing product quality.
