Abstract

An embodiment of the invention provides a gate drive circuit, and includes a plurality of gate drive units cascaded along a first direction, the at least one gate drive unit includes a first scanning signal input end, a second scanning signal input end, a first clock signal input end, a second clock signal input end, a reset signal input end, a first input end, a second input end and an output end, the output end of the gate drive unit of a previous stage arranged along the first direction is electrically connected with the first input end of the gate drive unit of a next stage, and the second input end of the gate drive unit of the previous stage arranged along the first direction is electrically connected with the output end of the gate drive unit of the next stage; the first input end of the first-stage gate drive unit arranged along the first direction and the second input end of the last-stage gate drive unit are mutually electrically connected and are connected to a trigger signal end; and the rest signal input ends of the gate drive units are mutually electrically connected and are connected to a reset signal end.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit in a display drive circuit, a driving method thereof, and a display device including the gate drive circuit. Background technique [0002] In recent years, with the development of display technology, the application of display panels has become more and more extensive. In the prior art, a display panel includes a plurality of scanning lines (gate lines), a plurality of signal lines (data lines), a scanning line (gate line) driving circuit and a signal line (data line) driving circuit. Each driving circuit is located in a non-display area of ​​the display device and is composed of a plurality of elements. When the display panel is working, the gate driving circuit in the display panel needs to generate scanning signals to drive each gate line in the array substrate one by one, so that the data signal can be transmitted to each pixel unit in the array...
