Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] The transistors used in all embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain of the transistors used here are symmetrical, there is no difference between the source and the drain. of. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the gate, one pole is called the source, and t...

Abstract

The invention provides a shifting register unit, a gate driving circuit and a display device, and relates to the technical field of display. The coupling capacitance of a thin film transistor can be reduced. Noise of an output signal can be reduced. The shifting register unit comprises an input module, a control module, a restoration module, an upwards-pulling module, a downwards-pulling module and a noise reduction module. The shifting register unit, the gate driving circuit and the display device are used for achieving scanning driving.

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 energy 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 furt...
