Abstract
A shift register includes a plurality of stages each for outputting k composite pulses each including an A-scan pulse and a B-scan pulse. At least one stage includes k A-sub-stages each for controlling a voltage at an A-set node and a voltage at least one A-reset node in response to an external A-control signal and generating an A-carry pulse based on the voltage at the A-set node, the voltage at the at least one A-reset node and any one A-clock pulse, a B-sub-stage for controlling a voltage at a B-set node and a voltage at least one B-reset node in response to an external B-control signal and generating a B-carry pulse, and a scan output controller for generating k A-scan pulses and k B-scan pulses and outputting one of the A-scan pulses and one of the B-scan pulses corresponding to each other as one composite pulse.
