Abstract

The invention discloses a shifting register unit, a driving method, a gate driving circuit and a display device, and belongs to the technical field of displays. The shifting register unit includes aninput sub-circuit, an output sub-circuit, a discharging sub-circuit and a noise reduction sub-circuit , wherein the discharging sub-circuit is respectively connected with the input signal terminal, the first power terminal and the pull-down node for outputting the first power signal to the pull-down node under the control of the input signal. In the shift register unit provided by the present invention, the discharging sub-circuit can control a potential of the pull-down node to be an inactive potential during an input phase, so as to prevent the noise reduction sub-circuit from affecting thepotentials of a pull-up node and an output terminal under the control of the pull-down node, and ensure the normal output of the shifting register unit.

Description

Technical field

[0001] The present invention relates to the field of display technology, and in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technology

[0002] The shift register usually includes a plurality of cascaded shift register units, each shift register unit is used to drive a row of pixel units, and the multiple cascaded shift register units realize row-by-row switching of each row of pixel units in the display device. Scan driver to display images.

[0003] In the related art, there is a shift register unit, which mainly includes an input sub-circuit, an output sub-circuit, a pull-down control sub-circuit and a noise reduction sub-circuit. Among them, the input subcircuit is used to charge the pull-up node according to the driving signal output by the upper-level shift register unit in the input stage, and the output subcircuit is used to output to the output terminal in the output stage under the ...
