Embodiment Construction

[0067] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0068] 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. According to the function in the circuit, the transistors used in the embodiments of the present invention are mainly switching transistors. 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, in order to distinguish the two poles of the transistor other than the gate, the source is called the first pole and the drain is called the second pole. Therefore, the gate of the transistor may also be called the third pole. According to the form in the figure,...

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 ...
