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 technical field of display. The shift register unit includes an input module, a maintaining module, an output module, a resetting module, and a pull-down module. After the input module provides an input signal with the potential, the maintaining module can control the potential of a second pull-up node to be the first potential, enables a transistor of the output module to remain an effective start state under the control of the second pull-up node when the potentialof a clock signal outputted by a clock signal end, and timely output the clock signal to the output end as a drive signal. Moreover, because the potential of the second pull-up node at the output stage is more stable, the load of the output end cannot be increased, and the time when the potential of a drive signal outputted by the output module changes to the first potential can be guaranteed tobe shorter, thereby guaranteeing the timely charging of all pixels in a display region, and improving the display quality.

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] The shift register usually includes a plurality of cascaded shift register units, and each shift register unit is used to drive a row of pixel units. The plurality of cascaded shift register units can realize the step-by-step shifting of each row of pixel units in the display panel. Line scan driver to display images. [0003] In related technologies, the input module of the shift register unit can control the potential of the pull-up node under the control of the input signal; the output module can input a clock signal to the output terminal under the control of the pull-up node. Wherein, the output module is usually provided with a capacitor and a driving transistor, the gate of the driving transistor is connected to the pull-up node, and the two ends of the cap...
