ABSTRACT:
A shift register comprises a plurality of stages, {Sn}, n=1, 2, . . . , N, N being a positive integer. In one embodiment, each stage Snincludes a pull-up circuit having an input for receiving one of a first clock signal, CK1,and a second clock signal, XCK1,an output for responsively outputting an output signal, On, and an input node Qn, a pull-up control circuit electrically coupled to the input node Qnand configured such that when receiving a first input signal, the pull-up control circuit responsively generates a signal that is provided to the input node Qnto turn on the pull-up circuit, a pull-down circuit electrically coupled to the input node Qnand configured to provide a first voltage to one of the input node Qnand the output of the pull-up circuit, and a pull-down control circuit configured to receive one of a third clock signal, CK2,and a fourth clock signal, XCK2,and responsively generate the first voltage to turn on the pull-down circuit of the stage Snand the pull-down circuit of one of the stage Sn−1and the stage Sn+1.
