Abstract

The invention proposes a display device and a shift temporary storage circuit therefor. The shift temporary storage circuit comprises a multistage shift temporary storage unit, wherein one shift temporary storage unit at any stage comprises the following modules: an input module, wherein an input stage transmits a signal to a boost node; a coupling pull-up module which generates a first pull-up signal and pulls the level of the voltage signal to a second level from the first level; an output module which performs the coupling and pulling-up of the level of the voltage signal to the third levelfrom the second level according to a clock signal, and outputs a grid scanning signal through an output end, wherein the coupling pull-up module generates a second pull-up signal when the pulse of the clock signal is finished, and the second pull-up signal acts on the boost node in a coupling manner, so as to enable the voltage signal to remain at the second level; a feedback module which receives a feedback signal, and pulls the level of the voltage signal and the level of the grid scanning signal to a preset low level.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display device with an array substrate gate driving circuit and a shift register circuit thereof. Background technique [0002] In recent years, Liquid Crystal Display (LCD) has been widely used due to its clear and precise image, flat display, thin thickness, light weight, no radiation, low energy consumption, and low operating voltage. When a traditional liquid crystal display performs gate driving, it mainly uses a gate driver chip (Gate Driver 1C) to realize. Since the gate driving chip needs to be connected to the display panel (Panel) through a connector, and multiple gate driving chips need to be used in one liquid crystal display, the manufacturing cost of the liquid crystal display is still relatively high. [0003] With the development of new technologies, many liquid crystal display panels have adopted Gate Driver Array (GOA) technology to replace e...
