发明名称 Gate driver and display apparatus having the same
摘要 <p>A gate driver (200) 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 (242), a pre-charging part (300), a pull-up part (210), and a pull-down part (220). The holding part (242) discharges an output terminal to an off-voltage in response to a first clock signal. The pre-charging part (300) turns off the holding part (242) 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 (210) 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 (220) discharges the first output terminal to the off-voltage in response to an output signal of a next stage.</p>
