Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe in detail the embodiments of the present invention in conjunction with the accompanying drawings.

[0047] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics, and the transistors used in the embodiments of the present invention are mainly switching transistors according to their functions in circuits. Since the source and drain of the switching transistor used here are symmetrical, the source and drain are interchangeable. In the embodiment of the present invention, the source is referred to as the first stage, and the drain is referred to as the second stage. According to the form in the accompanying drawings, it is stipulated that the middle terminal of the transistor is the gate, the signal input terminal is the sou...

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...
