Abstract
A shift register includes a plurality of shift register circuits. Each of the shift register circuits includes a first switch, an input circuit, a pull-down circuit and a ripple reduction circuit. The first switch is used to output a scanning signal of the shift register circuit according to voltage levels of a node and a clock signal. The input circuit is used to pull up the voltage level of the node according to a scanning signal of a previous shift register circuit. The pull-down circuit is used to pull down the voltage levels of the node and the scanning signal of the shift register circuit according to a scanning signal of a following shift register circuit. The ripple reduction circuit is used to suppress ripples on the voltage levels of the node and the scanning signal caused by the coupling effect of the clock signal.
