GATE DRIVER CIRCUIT OUTPUTTING SUPERIMPOSED PULSES

摘要

Provided is a gate driver circuit. The gate driver circuit includes a plurality of sequentially connected stages, and each of stages includes an input unit including two input transistors forming diode connection, a pull-up unit including a pull-up transistor and a bootstrap capacitor, and first and second pull-down units each including two transistors. According to embodiments, an input capacitor is further included which is connected to a node between the input unit and the pull-up unit. In addition, a carry unit is further included which is connected to an output terminal and formed to transmit an output signal in a high state or a low state to a next stage.

主权项

1. A gate driver circuit comprising a plurality of sequentially connected stages, an Nth (where N is a natural number) stage comprising:
an input unit configured to deliver a first carry signal to a first node in response to the first carry signal delivered from an (N−1)th stage and a first clock signal; and a pull-up unit configured to pull-up an input signal according to a signal level at the first node and to deliver the pulled-up input signal to an output terminal, wherein the pull-up unit comprises a bootstrap capacitor provided between the first node and the output terminal to bootstrap a signal level at the first node to a high level.
