Abstract
A shift register includes a signal generating circuit, a driving circuit, a reset circuit, and a control switch. The signal generating circuit includes a first switch for generating a first output signal according to a clock signal while the first switch is turned on, and a second switch coupled to an output end of the shift register for generating and transmitting a second output signal to the output end of the shift register according to the clock signal while the second switch is turned on. The driving circuit is for controlling the first and second switches according to an input signal received from an input end of the shift register. The reset circuit is for turning off the first and second switches and resetting the output signal outputted by the output end. The control switch is for resetting the output signal outputted by the output end.
