Abstract

The invention provides a shift register unit, a driving method, a gate driving circuit and a display device. The shift register unit comprises a sharing module and an output module; the sharing modulecontrols the potential of a pull-up node under the control of a input end, a reset end and a first clock signal input end; the output module is used for controlling grid driving signals output by 2Mgrid driving signal output ends under the control of the pull-up node, a noise-reducing control end and an output control end; wherein M is an integer greater than 2. The charging rate of shift register unit is high, and the narrow frame can be conveniently realized.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] In the existing display device, the driving transistor in the pixel circuit is an ordinary thin film transistor with only one gate, which cannot effectively reduce the voltage value of the high voltage VGH that needs to be provided, resulting in a low charging rate. In addition, the number of shift register units included in the existing gate drive circuit needs to be the same as the number of rows of pixel circuits set on the display panel, and it is not possible to use one-stage shift register units for at least two rows of pixel circuits to be connected to the corresponding gates, respectively. Pole drive signals, so a large number of transistors need to be used, which is not conducive to the realization of narrow borders. Contents of the invention [...
