GATE DRIVING CIRCUIT, IN WHICH PULL-UP PART IS COMPOSED OF A PLURALITY OF SWITCHING DEVICES

摘要

PURPOSE: A gate driving circuit is provided to improve the output characteristics of the gate driving circuit by increasing the overall size of the pull-up unit. CONSTITUTION: A gate driving circuit is connected a plurality of stages, each outputs the output signals subsequently. Each of the stages includes a pull-up unit(351), a pull-down unit(352), a pull-up driving unit(353) and a pull-down driving unit(354). The pull-up unit is composed of a plurality of switching device connected in parallel to supply a first clock or a second clock having an inverted phase to the first clock. The pull-down unit supplies the ground voltage to the output terminal. The pull-up driving unit is connected to the input node of the pull-up unit to turn on the pull-up unit in response to the output signal of the previous stage and to turn off the pull-up unit in response to the output signal of the following stage. And, the pull-down driving unit is connected to the input node of the pull-down unit to turn off the pull-down unit in response to the input signal and to turn on the pull-down unit in response to the output signal of the following stage.
