Embodiment Construction

[0060] 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.

[0061] 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 th...

Abstract

The invention discloses a shift register unit and a driving method thereof, a gate drive circuit and a display device, and belongs to the technical field of display. The shift register unit comprises a shift module, an initialization module and an output control module. The shift module can output a driving signal to a first control node. The initialization module can output an initialization signal to a second control node. The output control module is used for outputting the signal of the control node of which the potential is effective potential in the first control node and the second control node to an output end. Therefore, the shift register unit can normally scan and drive a display panel and can also output the initialization signal to the display panel under the control of the initialization module. The switching transistor in the pixel unit can be initialized by the initialization signal so that the switching transistor is enabled to discharge and the influence of the residual charge on the charging effect can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, a gate driving circuit and a display device. Background technique [0002] When displaying an image, the display device needs to use a shift register (ie, a gate driving circuit) to scan pixel units. [0003] The shift register in the related art includes multiple cascaded shift register units, each shift register unit corresponds to a row of pixel units, and when the shift register unit outputs a driving signal, the corresponding row of pixel units can be turned on. By the multiple cascaded shift register units, the row-by-row scan driving of each row of pixel units in the display device can be realized to display images. [0004] However, the working mode of the shift register unit in the related art is relatively simple, and the flexibility in driving is relatively low. Contents of the invention [0005] In order to solve t...
