Abstract

The invention provides a shift register unit, a control method thereof and a gate drive circuit. The invention comprises a first control circuit and an energy storage circuit which are used for directly controlling the potential of a first node, a pull-down control circuit, a second control circuit and a first pull-down circuit which are used for indirectly controlling the potential of a first node, and an output circuit which is used for outputting a first voltage signal provided by a first voltage end to a signal output end under the control of the potential of the first node. According to the shift register unit, the control method thereof and the gate drive circuit, the pulse width of the gate scanning signal can be adjusted, and various display requirements are met.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register, a control method thereof, a gate drive circuit and a display device. Background technique [0002] In the display industry, in order to reduce the production cost of the display panel and realize the narrow frame design of the display panel, more and more gate drive circuits adopt the Gate Driver on Array (GOA) technology, that is, the gate The switch circuit is integrated on the array substrate of the display panel. [0003] In the related art, the display device adopting the GOA technology has the problem that it is difficult to adjust the pulse width of the gate scanning signal. Contents of the invention [0004] Embodiments of the present invention provide a shift register unit, a control method thereof, and a gate driving circuit, so as to solve the problem of difficulty in adjusting the pulse width of a gate scanning signal in a display device ...
