Embodiment Construction

[0039] 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.

[0040]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 first electrod...

Abstract

The embodiment of the invention provides a shifting register unit, a grid driving circuit and driving method and a display device, and relates to the field of displayer manufacturing. The shifting register unit, the grid driving circuit and driving method and the display device can simplify wire connection design between shifting register units, and accordingly narrow frames of products are facilitated. The shifting register unit comprises an input module, an output module and an output control module. The input module is connected with an input end, a first control signal end and a first node. The output module is connected with the first node, a second node, a second control signal end, an output end and a second level end. The output control module is connected with the first node, the second node, the output end, a first level end and the second level end. The shifting register unit, the grid driving circuit and driving method and the display device are used for displayer manufacturing.

Description

technical field [0001] The invention relates to the field of display manufacturing, in particular to a shift register unit, a gate drive circuit, a drive method and a display device. Background technique [0002] In recent years, the development of displays has shown a trend of high integration and low cost. One of the very important technologies is the mass production of GOA (Gate Driver on Array, array substrate row drive). The gate switch circuit is integrated on the array substrate of the display panel by using GOA technology, so that the gate drive integrated circuit part can be saved, so as to reduce the product cost in terms of material cost and manufacturing process. The gate switching circuit integrated on the array substrate using the GOA technology is also called a gate driving circuit. [0003] Wherein, the gate drive circuit includes several shift register units, each shift register unit corresponds to a gate line, and specifically the output end of each shift...
