Gate driving circuit and display apparatus including the same

摘要

A gate driving circuit includes N stages (where N is a natural number greater than or equal to 2). The N stages are cascaded, and each of the N stages has a gate line connected thereto. A first stage group includes k stages of the N stages (where k is a natural number less than N), and the first stage group outputs a first output signal in response to a start signal. A second stage group (including N−k stages) generates a second output signal in response to the first output signal and outputs the second output signal to a corresponding gate line. The first stage group includes a first buffer and a second buffer, each of which receives the start signal. A size of the first buffer is smaller than a size of the second buffer.

1. A gate driving circuit comprising:
N stages, where N is a natural number greater than or equal to 3, the N stages are cascaded, and each of the N stages has a respective gate line connected and corresponding thereto; a first stage group including k stages of the N stages, where k is a natural number less than N, and which outputs first output signals in response to a same start signal; and a second stage group including N-k stages, and which generates second output signals in response to the corresponding first output signals from the first stage group and outputs the second output signal to a corresponding gate line, wherein the first stage group comprises first buffers which receive the start signal and the second stage group comprises second buffers which receive the first output signals, and a size of the first buffer is smaller than a size of the second buffer, wherein respective first buffers are diode-connected to respective first terminals of the k stages which receive the same start signal, and respective second buffers are diode-connected to respective second terminals of the N-k stages which receive the first output signals.
