  • Publication number: 20090073105
    Abstract: An exemplary shift register includes a plurality of shift register units, each of which includes an output circuit, an input circuit, and a logic circuit. The output circuit includes a clock transistor, a voltage stabilizing transistor, and an input circuit for receiving signals output by a previous shift register unit. The logic circuit receives signals output by the input circuit. When the input circuit outputs signals to switch on the clock transistor, the logic circuit outputs a low level voltage signal to shut off the voltage stabilizing transistor. Thus, the output circuit outputs signals via the clock circuit. On the other hand, when the input circuit outputs signals to shut off the clock transistor, the logic circuit outputs a high level voltage signal to turn on the voltage stabilizing transistor, so as to maintain the output circuit to output low level voltage signal.
