ABSTRACT:
A shift register unit includes a plurality of register units electrically coupled in cascade. Each register unit outputs an output pulse according to a first clock signal, a second clock signal and an output pulse of a previous register unit. Each register unit includes a first switch unit, a second switch unit, a third switch unit, a fourth switch unit, and a driving unit. The first switch unit is used for conducting the input pulse to a first node when the first switch is turned on. The second switch unit is used for conducting the output pulse of the register unit according to the first clock signal to an output end when the second switch unit is turned on in response to the input pulse. The third switch unit electrically coupled to a supply end is used for conducting a supply voltage to the output end when the second switch unit is turned off. The fourth switch unit electrically coupled to the supply end is used for conducting the supply voltage to the first node when the fourth switch unit is turned on in response to a driving pulse. The driving unit is used for providing the driving pulse according to the first clock signal, the second clock signal, and the input pulse.
