    Abstract: 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.

    Abstract: An audio/video (A/V) device having a volume control function for external audio reproduction units by using volume control buttons of a remote controller is provided. The A/V device includes speakers, an audio output port for externally outputting an audio signal, an audio signal processing unit for reproducing and amplifying the audio signal and applying the amplified audio signal to the speakers or the audio output port, a memory unit for storing volume control values, and a control unit for applying to the audio signal processing unit any of the volume control values stored in the memory based on whether the external audio reproduction unit is plugged in the audio output port. The control unit controls the audio signal processing unit to adjust the volume control values for the audio output port by the volume control buttons when the external audio reproduction unit is plugged in the audio output port.

    Abstract: 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.

    Abstract: A gate drive circuit includes plural stages connected together one after each other. Each of the plural stages includes a circuit transistor, a capacitor part, a first connection part and a second connection part. The circuit transistor outputs the gate signal through a source electrode in response to a control signal applied through a gate electrode. The capacitor part includes a first electrode, a second electrode formed on the first electrode, and a third electrode formed on the second electrode. The first connection part electrically connects the gate electrode of the circuit transistor and the second electrode of the capacitor part. The second connection part electrically connects the source electrode of the circuit transistor and the first electrode of the capacitor part. Thus, an integrated size of a gate drive circuit may be decreased, and a reliability of a gate drive circuit may be enhanced.

    Abstract: In a gate drive circuit including stages which are cascaded and which output gate signals each of the stages includes a first node, an output part, a first holding part and a second holding part. A voltage of the first node is converted to a high voltage in response to one of a vertical start signal and a carry signal of one of previous stages. The output part outputs a first clock signal as a gate signal through an output terminal in response to the high voltage of the first node. The first holding part applies a first low voltage to the output terminal, in response to a gate signal output from at least one of following stages. The second holding part applies a second low voltage, which is less than the first low voltage, to the first node in response to a gate signal output from at least one stage among following stages.
