Abstract

The invention discloses a shifting register unit, a driving method, a gate electrode driving circuit and a display device, which belong to the field of display technologies. The shifting register unit comprises a charging module, a resetting module, a pull-up module, a pull-down module, a denoising module and a pre-resetting module, wherein the pre-resetting module is connected with a frame switching-on signal end, a third power supply signal end, a pull-up node and an output end, and is used for resetting the pull-up node and the output end under the control of a frame switching-on signal. Therefore, the shifting register unit which is switched on by mistake can be switched off timely by means of the pre-resetting module, so as to prevent the occurrence of tail end white line defect of a display panel caused by the mistaken switching-on of the last stage shifting register unit, and effectively improve the output stability of a shift register.

Description

Technical field

[0001] The present 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 needs to use a shift register (that is, a gate drive circuit) to scan the pixel unit. The shift register includes multiple shift register units. Each shift register unit corresponds to a row of pixel units. The shift register unit realizes the progressive scanning drive of each row of pixel units in the display panel to display images.

[0003] There is a shift register unit in the related art, and the shift register unit mainly includes a charging module, a reset module, a pull-up module, and a noise reduction module. Among them, the charging module is used to charge the pull-up node, the pull-up module is used to pull up the level of the output terminal to a high level under the control of the pull-up node, and the ...
