Shift register unit and driving method thereof, grid electrode drive circuit and display device

Abstract

The invention belongs to the display technical field, and specifically relates to a shift register unit and a driving method thereof, a grid electrode drive circuit and a display device; the shift register unit comprises the following elements: an input module used for outputting a pull-up control signal to a pull-up module according to a first DC voltage signal and a start signal; the pull-up module used for outputting a same level shift register signal through a first output end according to a second DC voltage signal and a clock signal, and used for outputting a start signal of a next level shift register unit through a second output end; a pull-down control module used for outputting a pull-down control signal to a pull-down module according to the second DC voltage signal, a third DC voltage signal and the clock signal; a pull-down module used for outputting a pull-down signal of a first output end, a second output end and a pull-up point to the pull-up module; a reset module used for outputting a reset signal to the pull-up module according to a fourth DC signal and the reset signal. The shift register unit uses DC voltage to serve as input signals of the pull-up module and the pull-down control module, and is stable, and small in power consumption.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a shift register unit, a driving method thereof, a gate driving circuit and a display device. Background technique [0002] The driving method of traditional display devices is to use an external driver chip to drive the pixels on the display panel to display images. In order to reduce the number of components and reduce manufacturing costs, it has become a mainstream technology to directly fabricate the structure of the driving circuit on the display panel in recent years, such as The technology of integrating the gate driving circuit into the liquid crystal panel (Gate On Array, GOA for short) is applied. [0003] At present, the driving circuit is usually driven by an AC signal, which inevitably has a certain signal delay effect, increases the power consumption of the driving circuit, reduces the driving capability, and is difficult to apply to a large-size liquid...
