    摘要： A gate driving circuit and a display device having the same, a pull-up unit pulls up a current gate signal by using a first clock signal during a first period of one frame. A pull-up driver coupled to the pull-up unit receives a carry signal from one of the previous stages to turn on the pull-up unit. A pull-up unit receives a gate signal from one of the next stages, discharges the current gate signal to an off voltage level, and turns off the pull-up unit. A holder holds the current gate signal at the voltage level. An inverter turns on/off the holder in response to a first clock signal. A ripple preventer has a source and a gate coupled in common to an output terminal of the pull-up unit and a drain coupled to an input terminal of the inverter, and includes a ripple preventing diode for preventing a ripple from being applied to the inverter.

    摘要： A gate driver comprises a shift register that has a plurality of stages connected together and outputs a gate signal comprising a first pulse and a second pulse to a gate line. A stage includes a holding part, a pre-charging part, a pull-up part, and a pull-down part. The holding part discharges an output terminal to an off-voltage in response to a first clock signal. The pre-charging part turns off the holding part and outputs the first clock signal as the first pulse to the output terminal in response to an output signal of a previous stage. The pull-up part outputs a second clock signal as the second pulse to the output terminal in response to the output signal of the previous stage. The pull-down part discharges the first output terminal to the off-voltage in response to an output signal of a next stage.

    摘要： A gate driving circuit includes stages connected in series. In a stage, a pull-up part pulls up a present gate signal to a level of a first clock signal, and a pull-down part receives a next gate signal from a next stage to discharge the present gate signal to an off-voltage. A pull-up driving part turns on or turns off the pull-up part and the carry part. A holding part holds the present gate signal at the off-voltage and a present inverter turns on or turns off the holding part in response to the first clock signal. A ripple preventing capacitor is connected between a present node and an output terminal of a previous stage's inverter to prevent a ripple at the present Q-node in response to an output signal from the previous inverter.

    摘要： In an array substrate and a display apparatus, a gate line receives a gate pulse during a present 1H period and a data line receives a pixel voltage having a polarity inverted at every frame. When a thin film transistor is turned on in response to the gate pulse during the present 1H period, a pixel electrode receives the pixel voltage through the thin film transistor during the present 1H period. A pre-charging part pre-charges the pixel electrode to a common voltage that is a reference voltage of the pixel voltage in response to a previous gate pulse during a previous 1H period.
