A shifting register unit, a driving method, a gate drive circuit and a display device

Abstract

The invention provides a shifting register unit, a driving method, a gate drive circuit and a display device and belongs to the technical field of display. The shifting register unit comprises an input module, a resetting module, a pull-up module, a pull-down module and a noise reduction module. The input module is used for outputting a first power source signal to an pull-up node; the resetting module is used for outputting a second power source signal to the pull-up node; the pull-up module, under the control of the pull-up node, outputs a first clock signal to an output end; the pull-down module, under the control of a second clock signal and the pull-up node, outputs a third power source signal or the second clock signal to a pull-down node; the noise reduction module is used for outputting the third power source signal to the pull-up node and the output end separately under the control of the pull-down node. The shifting register unit is simple in circuit structure and control process and solves the problem of complicated circuit structure of shifting register units in the prior art.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] When the display device displays an image, it is necessary to use a shift register (gate drive circuit) to scan the pixel units. The shift register includes a plurality of shift register units, and each shift register unit corresponds to a row of pixel units. The bit register unit implements row-by-row scan driving of each row of pixel units of the display device to display images. [0003] In order to improve the display flexibility of the display device, there is a shift register capable of bidirectional scanning in the related art, and the shift register can realize forward scanning and reverse scanning of each row of pixel units of the display device. Each shift register unit usually controls the potential level of the output signal through a plurality of tran...
