    摘要: 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.

    摘要: A gate drive circuit includes a plurality of driving stages. An n-th (‘n’ is a natural number) driving stage includes a pull-up part, a carry part, a first pull-down part, a first pull-up/down control part and a second pull-up/down control part. The first pull-up/down control part applies a first power signal of an ON voltage to a control terminal of the pull-up part in a forward direction mode, and applies the first power signal of a second OFF voltage to a control terminal of the pull-up part in a reverse direction mode. The second pull-up/down control part applies a second power signal of the second OFF voltage to the control terminal of the pull-up part in the forward direction mode, and applies the second power signal of the ON voltage to the control terminal of the pull-up part in the reverse direction mode.

    摘要: A gate driving circuit includes a plurality of stages connected to each other. An m-th stage (‘m’ is a natural number) of the stages includes a pull-up part, a pull-down part, a first holding part and a second holding part. The pull-up part outputs a high voltage of a clock signal as a high voltage of an m-th gate signal in response to a high voltage applied to a first output control part. The pull-down part pulls down the high voltage of the m-th gate signal to a first low voltage in response to a high voltage of an (m+1)-th gate signal. The first holding part holds a voltage applied to the first output control part as a second low voltage having a level lower than the first low voltage. The second holding part holds a low voltage of the m-th gate signal to the first low voltage.
