  • Publication number: 20130335392
    Abstract: A gate drive circuit in which multiple stages are connected together one after each other. An n-th stage includes a pull-up part, a carry part, a pull-down part, a switching part, a first maintaining part and a second maintaining part. The pull-up part outputs a high voltage of a first clock signal. The carry part outputs a high voltage of the first clock signal. The pull-down part pulls-down the n-th gate signal into a first low voltage. The switching part outputs a first signal synchronized with the first clock signal during an interval other than a high voltage output interval of the n-th carry signal. The first maintaining part maintains the n-th gate signal at the first low voltage in response to the first signal. The second maintaining part maintains the n-th gate signal at the first low voltage in response to a second signal.

  • Publication number: 20120139883
    Abstract: A gate drive circuit includes a shift register in which plural stages are cascade-connected to each other. In an n-th stage, a pull-up part outputs a high voltage of a clock signal to an output node as a high voltage of an n-th gate signal in response to a high voltage on a first node. A pull-down part pulls the high voltage of the n-th gate signal down to a first low voltage in response to an (n+1)th carry signal. A discharging part discharges the first node to a second low voltage level lower than the first low voltage level in response to the (n+1)th carry signal. A carry part outputs the high voltage of the clock signal as an n-th carry signal (mirroring the n-th gate signal) in response to a high voltage on the first node.
