Problems solved by technology

With the continuous development of display devices, people's demand for narrow bezel display devices is also increasing. The key to narrow bezel display devices is how to further reduce the number of transistors used in the GOA circuit. In the design of the existing GOA circuit, due to the shift The limitation of multiple functional modules in the bit register unit, the structure is relatively complex, so it is difficult to further reduce the number of transistors used

Embodiment Construction

[0021] 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. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0022] 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 of the poles is called the first pole, and the other pole is call...

Abstract

The embodiment of the invention provides a shifting register unit, a gate driving circuit and a display device, and relates to the technical field of display. The shifting register unit comprises an input module, a first output module and a second output module. Compared with the prior art, the invention has the advantages that the structure of the shifting register unit can be effectively simplified; and the using quantity of transistors is further decreased. The embodiment of the invention is used for realizing 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] The basic principle of a Thin Film Transistor-Liquid Crystal Display (TFT-LCD) to realize a frame display is to input a square wave of a certain width to each pixel row from top to bottom through the gate (Gate) drive. Strobe, and then drive the source (Source) to output the signal required by each row of pixels from top to bottom in turn. At present, the manufacture of display devices with such a structure is usually to make the gate drive circuit and the source drive circuit on the On the glass panel, but when the resolution is high, the output of the gate drive and the source drive are more, and the length of the drive circuit will also increase, which will not be conducive to the bonding process of the module drive circuit. [0003] In order to overcome the above problems, the m...
