Abstract

The embodiment of the invention provides a shift register unit, a gate drive unit and a display device and relates to the technical field of display so as to prevent that a level of a pull-up control node which should be at a high-level state is mistakenly driven down. The shift register unit includes an input module, an output module, a voltage stabilizing module and a resetting module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a gate drive circuit and a display device. Background technique [0002] Liquid Crystal Display (LCD for short) has the advantages of low radiation, small size and low power consumption, and is widely used in electronic products such as notebook computers, flat-screen TVs or mobile phones. [0003] The liquid crystal display is composed of interlaced pixel matrixes located in the horizontal and vertical directions. When the liquid crystal display is displayed, the data drive circuit can latch the input display data and clock signals in timing order, convert them into analog signals and input them to the liquid crystal panel. The gate drive circuit can convert the input clock signal into a voltage for controlling the on / off of pixels through the shift register, and apply it to the gate line of the liquid crystal panel row by row. [0004] In order to furth...
