Abstract: The invention provides scan signal generating circuits and scan signal generating methods thereof. The scan signal generating circuit comprises a first, a second and a third switch and a capacitor, and generates a scan signal driving a pixel. The first switch is turned on to couple an input signal to a first node when a first clock signal is high. The second switch, controlled according to the voltage level at the first node, is turned on to couple a second clock signal that has an inverse phase of the first clock signal to an output terminal of the scan signal generating circuit when the voltage level at the first node is high. When the first clock signal is high, the third switch is turned on to couple the output terminal to a first voltage source. The first node is coupled to ground by the capacitor.

Abstract: A display device is provided. The display device includes at least a substrate having a display region and a periphery region, a first ESD circuit and a pad disposed on the periphery region respectively. The pad has a first end near the display region and a second end near an edge of the substrate. A first connection line extended from the first end is electrically connected with a second connection line extended from the ESD circuit.
