Abstract

The embodiment of the invention provides a shift register unit, a driving method, a gate driving circuit and a display device, relates to the technical field of display, and can solve a problem that aconventional GOA circuit cannot meet the requirement of the narrow frame of a display device due to the complicated structure. An output unit in the shift register unit includes a first output moduleconnected with a first signal output end, and a second output module connected with a second signal output end. The first signal output end and the second signal output end are used for connecting different gate lines. A pull-down unit comprises a first pull-down module and a second pull-down module. The output unit is connected with a pull-up node, and the pull-down unit is connected with the pull-down node. The pull-up node is used for controlling the first signal output end and the second signal output end to sequentially output a first working signal and a second working signal. The pull-down node is used for controlling the first signal output end and the second signal output end to stop outputting the first working signal and the second working signal.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit and a driving method, a gate driving circuit, and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) are increasingly being used in the field of high-performance displays, and in order to To increase the screen-to-body ratio of the display device, the gate drive circuit in the prior art is usually set as a GOA (Gate Driver on Array, array substrate row drive) circuit. [0003] The shift register unit in the existing GOA circuit includes a detection unit, a display unit, and a connection unit. In this way, the structure of the circuit is very complicated, and it occupies a large area, which cannot meet the requirements of a high-resolution display device for a narrow frame. Summary of the invention [0004] The embodiments of the present invention provide a shift regi...
