Example Embodiment

[0049]In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] 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...

Abstract

The invention discloses a shift register unit, a driving method, a gate drive circuit and a display device, and belongs to the technical field of display. The shift register unit comprises an input module, an output module, a pull-down control module and a pull-down module; the input module is used for inputting an input signal from a signal end into a pull-up node under the control of a first clock signal from a first clock signal end; an output module is used for inputting a second clock signal from a second clock signal end into an output end under the control of the pull-up node; the pull-down module is used for inputting a first clock signal into the pull-down node under the control of the first clock signal and inputting a power signal from a power end into the pull-down node under the control of the pull-up node; the pull-down module is used for inputting the power signal into the output end under the control of the pull-down node. Accordingly, the layout area occupied by the gate drive circuit in the display device is reduced, and narrow bezel is obtained conveniently.

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 gate driver circuit (English: Gate Driver on Array; GOA for short) to scan the pixel unit. The gate driver circuit (also called a shift register) includes multiple cascaded shift registers. A register unit, each shift register unit corresponds to a row of pixel units, and a plurality of shift register units implements row-by-row scan driving of the pixel units of the display device to display images. [0003] However, with the increase in the number of pixel units in the display device, the number of lines scanned by the gate drive circuit in one frame time increases, and the demand for ultra-narrow bezel display devices requires that the layout area of ​​the shift register unit be larger. smaller...
