  • Patent number: 7446748
    Abstract: A driving circuit for a flat panel display device includes first and second generation units generating m-phase circulation enable control clocks and n-phase circulation form generation clocks; and a plurality of shift register stages generating output signals by using the m-phase circulation enable control clocks and the n-phase circulation form generation clocks. Each shift register stage includes an input terminal receiving the m-phase circulation enable control clocks; first and second nodes outputting first and second signals, respectively, using the m-phase circulation enable control clocks; a first transistor connected to the first node and receiving the n-phase circulation form generation clocks; a second transistor connected to the second node and the first transistor; and an output terminal between the first and second transistors and outputting one of the output signals.
