Shift register unit, driving method, gate driving circuit and display device

Abstract

The invention discloses a shift register unit, a driving method, a gate driving circuit and a display device, and belongs to the field of display technology. The shift register unit comprises a control module, an output module and an angle cutting module; the control module is separately connected with an input signal end, a reset signal end, a control signal end, a first clock signal end, a pull-up node and an output end, and is used for controlling the potentials of the pull-up node and the output end; the output module is separately connected with a second clock signal end, the pull-up node and the output end, and is used for outputting a second clock signal from the second clock signal end to the output end; the angle cutting module is separately connected with the output end and a third clock signal end, and is used for outputting a third clock signal to the output end, in order to pull down the potential of signals output by the output end of the shift register unit at the second output phase, so as to retard the amplitude of gate voltage changes and avoid the phenomena of flicker, ghosts and the like appearing on pictures. The invention is used for displaying images.

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 cascaded shift register units, and each shift register unit corresponds to a row of pixel units, and can Scanning pulse signals are output to the gates of the thin film transistors in the row of pixel units, and the pixel units of the display device are driven by a plurality of shift register units to scan and drive row by row to display images. [0003] In the related art, there is a shift register unit, which usually controls the potential level of the output signal at the output terminal through a plurality of transistors and capacitors. However, there is usually a parasitic capacitance betwe...
