Abstract

The invention discloses a gate drive circuit and a display device. Each stage of the gate drive unit in the gate drive circuit includes: a main circuit, which is used according to the first input signal, second input signal, first clock signal, second The second clock signal and the third clock signal generate the first gate drive signal; and the pull-down circuit is used to generate the first pull-down signal and the second pull-down signal according to the second clock signal and the fourth clock signal, and the main circuit The output end for providing the first gate signal is connected to the output end of the pull-down circuit for providing the first pull-down signal and the second pull-down signal respectively, so that the first pull-down signal and the second pull-down signal The pull-down signal pulls down the first gate driving signal to form the gate driving signal of the gate driving unit of the current stage. The display device provided by the present invention has a stable output and can be applied to a narrow frame design, and has a wider range of applications.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit and a display device. Background technique [0002] A display device generally includes a display panel, a gate driving circuit and a source driving circuit. Wherein, the display panel includes a pixel array formed by a plurality of pixel units, and each pixel unit includes a thin film transistor. In this pixel array, the gates of the thin film transistors in the pixel units in the same row are connected to the gate drive circuit through the same scan line, and the gate drive circuit gates the pixels in each row of the pixel array row by row through multiple scan lines. unit; the source or drain of the thin film transistors in the pixel units in the same column are connected to the source drive circuit through the same data line, and the source drive circuit applies a grayscale voltage to each column of pixel units through multiple data lines, thereby Caus...
